The short answerLet AI do the heavy lifting, but keep the science yours. Ask Claude or ChatGPT to pull the main finding, key numbers and methods from your paper and rewrite them as 400–600 words of poster text; make data figures from your real data in Python or R; build the layout in PowerPoint, Canva or as an HTML poster; check every number; export an exact-size PDF (A0 is 841 × 1189 mm, body text 32–40 pt); upload the PDF to GitHub Pages and put a QR code to it on the poster; then print on paper or fabric and archive the final PDF with a DOI.

Want to use AI for your whole research workflow?My course Using AI Tools in Scientific Writing covers literature search, reading papers, writing, citations, figures and presentations with AI, responsibly and step by step.Explore the course → The night before my first international conference, I was still moving text boxes around in PowerPoint at 2 a.m. The poster had 1,800 words, tiny figures copied from the paper and a title nobody could read from more than one step away. Visitors walked past in seconds. The research was good; the poster was not. Today, students ask me how to avoid that night. The answer is a clear process and the right AI tools. In my recent videos I made six different posters from one paper, my Nature Communications article, with Claude inside PowerPoint, in portrait and landscape (see four of them below), in a fraction of the time it used to take. But AI is only half the job: you still need the right size, readable fonts, honest figures, a print-ready PDF and a way for people to take your poster home. Whether you need a research poster for a PhD seminar, an academic poster for an international conference or an e-poster for a virtual meeting, this guide gives you the full A–Z process: prompts you can copy, a free, tested A0 research poster template, Python scripts for figures and QR codes, and step-by-step instructions to host your poster for free on GitHub Pages.

Section 1What makes a great conference poster? Quick answerA great conference poster states its main finding in a large title or banner that people can read from a few metres, tells the story with figures more than text (about 300–800 words), follows a clear reading order, uses fonts large enough to read from 1.5–2 metres, and makes it easy to follow up with a QR code and contact details. It is an advertisement for your research and a starting point for a conversation, not a paper on a wall. Think about how people actually move through a poster session. Most visitors give each poster a few seconds while walking past. Some stop for half a minute. Only a few read everything. The classic paper Ten Simple Rules for a Good Poster Presentation (PLOS Computational Biology) makes the same point: a poster is read in passing, so it has to work at a glance. Design for all three:

3 secondsThe headlineA title that states the finding and a big main-finding banner. This alone should tell the story. 30 secondsThe figuresOne or two clear figures with large labels and a key number, plus three conclusion bullets. 3 minutesThe detailsBackground, methods, extra results, references and a QR code to the full PDF.

Typical posterTitle: "Effects of different organic amendments on selected parameters of wheat". 1,800 words, paper figures pasted at small size, 20-pt text, no contact details. Great posterTitle: "Biochar and compost increase wheat yield by 42% on degraded soils". 500 words, two large figures, 40-pt text, a QR code to the PDF and your email.

The anatomy of a research poster

Title band: a finding-style title, authors, affiliations, logos Main-finding banner: one sentence with the key result in large type Background and question: why this matters, in two or three sentences Methods: a small diagram or flow chart beats a paragraph Results: the biggest area on the poster, mostly figures Conclusions: three bullets and one "why it matters" line Footer: two or three references, funding, contact and a QR code

Quick answerAlways follow the conference instructions first: they give the board size, orientation and sometimes a template. The most common format is A0 portrait (841 × 1189 mm). In North America, 48 × 36 inches landscape or 36 × 48 inches portrait is common. Choose a three-column layout for portrait, four columns for landscape, and leave about 2–3 cm of margin on every side.

Your checklist before you design anything

Board size and orientation from the conference website (portrait or landscape matters). Deadlines: some conferences also want a PDF or e-poster uploaded in advance. Template or branding rules from the conference or your university. AI policy of the conference and your institution: what is allowed and whether you must disclose it. Printing: will you print at home, at your university, online, or at the venue? Audience: specialists in your field, or a mixed audience? This decides how much background you need.

Two layout styles: the classic layout uses columns for Background, Methods, Results and Conclusions. The #BetterPoster style, popularised by Mike Morrison in How to create a better research poster in less time, puts one very large main finding in the centre and moves details to the sides. For crowded sessions, the big-finding style attracts more visitors; the template in this guide combines both with a large main-finding banner. Key takeawaysConference rules beat any template.A0 portrait and 48 × 36 in landscape are the common sizes.Body text 32–40 pt on A0. ↑ Back to topNext: Step 2–3: poster text with AI → Section 4Step 2–3: how do you turn your paper into poster text with Claude or ChatGPT? Quick answerUpload your paper PDF to Claude or ChatGPT and ask for the single main finding, three to five key results with their exact numbers and sources, the question, methods and conclusions. Then ask it to rewrite these as 400–600 words of poster text with word limits per section and a list of every number used with its source. Check each number against your paper yourself before you design anything. The secret is to work in two steps. First, ask the AI to extract the story and show you where every number comes from. Only then ask it to write. This keeps the text faithful to your paper and makes checking easy. Copy these prompts and replace the parts in brackets (my prompt engineering guide explains why this structure works): Prompt 1: extract the story from your paperCopy templateYou are helping me turn my research paper into a conference poster. Read the attached paper (PDF) and give me:

1. The ONE main finding in a single sentence of at most 20 words, written for a scientist from a neighbouring field (this becomes the poster headline). 2. Three to five key results, each with the exact number from the paper and the table or figure it comes from (for example "Table 2"). 3. The research question in one sentence. 4. The methods in at most five short bullet points. 5. Two or three conclusions and one "why it matters" sentence. 6. Which one or two figures from the paper best support the main finding, and why.

Rules: use only information from the paper. If something is not in the paper, write "NOT IN PAPER". Do not round or change any number. Prompt 2: write the poster text with word limitsCopy templateNow write the poster text from your summary. Constraints: - Poster size: A0 portrait, three columns. Total text: 400-600 words. - Sections: Title (max 15 words, states the finding), Main finding (max 25 words), Background (max 60 words), Question (1 sentence), Methods (max 70 words), Results (max 100 words plus figure captions), Conclusions (3 bullets), Why it matters (1 sentence), References (max 3). - Short sentences, active voice, no abbreviations without explanation. - Every number must match the paper exactly. After the text, list each number you used with its source (table/figure/page) so I can check it. Check before you design

Every number matches the paper, with the same units and decimal places The title states the finding in plain words (no unexplained abbreviations) No claim is stronger than your results (for example "causes" instead of "is associated with") References and author names are correct; AI sometimes invents citations The text sounds like you: read it aloud and edit anything that does not

Key takeawaysExtract first, write second.Ask the AI to cite the source of every number.You check every number and reference yourself. ↑ Back to topNext: Step 4: figures → Section 5Step 4: how do you make figures that work on a poster? Quick answerMake data figures from your real data, not with AI image tools. Re-draw figures for the poster instead of pasting them from the paper: use large fonts (about 28 pt in the figure file), simple charts, direct labels, colour-blind-safe colours, and export as SVG (vector) or as PNG at 300 DPI. Use Excalidraw or draw.io for methods diagrams, and AI image generation only for illustrations such as a graphical abstract. Paper figures are designed for an A4 page you hold in your hand. On a poster they need bigger text, fewer panels and stronger colours. Ask Claude or ChatGPT to write the plotting code for you, then run it on your real data: Prompt 3: generate a poster-ready figure scriptCopy templateWrite a Python script with matplotlib that makes a poster-ready figure from this data: [paste a small table or describe the CSV columns]. Requirements: figure size 12 x 8.5 inches, base font size 28, colour-blind-safe colours (Okabe-Ito), no top/right axis lines, values written on the bars, error bars if I give standard errors, and save as both SVG and 300-DPI PNG. Here is the script I used for the example poster in this guide. It creates two figures as SVG and 300-DPI PNG files with the Okabe-Ito palette, which stays readable for people with colour vision deficiency: make_figure.pyCopy# make_figure.py: poster-ready figures (large fonts, colour-blind-safe colours, vector output) # pip install matplotlib import matplotlib.pyplot as plt import numpy as np

# Example data: replace with your own results treatments = ["Control", "Biochar\n5 t/ha", "Biochar\n10 t/ha", "Biochar\n+ compost"] season1 = [3.0, 3.5, 3.9, 4.3] season2 = [3.2, 3.7, 4.1, 4.5] mean = [(a + b) / 2 for a, b in zip(season1, season2)] error = [0.20, 0.25, 0.22, 0.27] colours = ["#9AA0B8", "#56B4E9", "#0072B2", "#009E73"] # Okabe-Ito palette, safe for colour blindness

plt.rcParams.update({"font.size": 28, "font.family": "DejaVu Sans", "axes.spines.top": False, "axes.spines.right": False})

# Figure 1: mean yield per treatment fig, ax = plt.subplots(figsize=(12, 8.5)) bars = ax.bar(treatments, mean, yerr=error, capsize=10, color=colours, width=0.65) ax.bar_label(bars, labels=[f"{v:.1f}" for v in mean], padding=12, fontsize=28, fontweight="bold") ax.set_ylabel("Grain yield (t/ha)") ax.set_ylim(0, 5.3) ax.tick_params(axis="x", labelsize=24) fig.tight_layout() fig.savefig("fig1.svg") # vector for the poster fig.savefig("fig1.png", dpi=300) # 300 DPI raster for PowerPoint or Canva

# Figure 2: the same pattern in both seasons fig, ax = plt.subplots(figsize=(12, 8.5)) x = np.arange(len(treatments)) ax.bar(x - 0.2, season1, 0.38, label="Season 1", color="#56B4E9") ax.bar(x + 0.2, season2, 0.38, label="Season 2", color="#E69F00") ax.set_xticks(x, treatments, fontsize=24) ax.set_ylabel("Grain yield (t/ha)") ax.set_ylim(0, 5.3) ax.legend(frameon=False, loc="upper left") fig.tight_layout() fig.savefig("fig2.svg") fig.savefig("fig2.png", dpi=300) print("Saved fig1 and fig2 as SVG and 300-DPI PNG") TerminalCopypip install matplotlib python make_figure.py Result: four files: fig1.svg, fig1.png, fig2.svg and fig2.png. Use the SVG files in HTML or Canva, and the PNG files in PowerPoint if SVG import gives you trouble. Graphical abstracts and illustrations with AI AI image generators are useful for a visual summary, icons, or a simple background. Keep data out of them, and keep text to a minimum because image models still make spelling mistakes. Prompt 4: a graphical abstract with ChatGPT or GeminiCopy templateCreate a clean, flat-style graphical abstract (landscape 16:9, white background) showing this story from left to right: [problem] -> [what we did] -> [main result]. Use simple icons, no more than 15 words of text in total, and a colour-blind-safe palette. Do not draw any chart or numbers: I will add real figures myself.

Never use AI to create or "improve" results: charts, microscopy, gels, blots or photos of experiments must come from your real data. Generated or altered result images are research misconduct, and many journals and conferences screen for them.

Key takeawaysRe-draw figures for the poster with big labels.SVG for sharpness, 300-DPI PNG as a backup.AI images for illustrations, never for data. ↑ Back to topNext: Step 5: design the layout → Section 6Step 5: how do you design the poster layout with AI? Quick answerChoose one of three routes. PowerPoint with Claude (or Copilot) is the most familiar: set a custom slide size such as 84.1 × 118.9 cm and let Claude build and refine the layout. Canva offers ready-made poster templates and AI design features. Or ask Claude to generate the poster as a single HTML file with exact A0 page size, which you can edit like a web page and print to PDF from Chrome. Route A: PowerPoint with Claude

Set the slide size: Design → Slide Size → Custom: width 84.1 cm, height 118.9 cm for A0 portrait. PowerPoint allows up to 142.24 cm (56 inches) per side, so 48 × 36 in also fits (see Microsoft's guide to changing slide size). Give Claude your poster text and figures and ask for a three-column layout with a title band, a main-finding banner and a footer with a QR code space. Ask for variations: portrait and landscape, different colour themes. Pick one and refine it. Replace placeholder images with your real figures and logos, then check alignment with the guides.

Short · 0:25Create Posters using Claude code for conference from your published papers or results. A quick look at making posters with Claude Code and PowerPoint. Example: four posters from one paper with Claude Code in PowerPoint To show what this route can do, I gave Claude Code my own published paper and asked it to design posters with the Claude add-in for PowerPoint. In one session it produced four very different designs from the same results: a classic layout, a big-number #BetterPoster layout, a methods workflow and a condition comparison. All four use the real numbers from the paper and editable PowerPoint charts, so I could check and change every value. The source paperTufail, M. A. et al.

Click a poster to open it at full size. These are 9:16 previews; for printing, set the slide to your conference size (for example A0) before you ask Claude for the layout. Try it with your own paper: open PowerPoint with the Claude add-in, attach your paper PDF and ask: “Design four conference posters from this paper in different styles (classic sections, one big headline number, a methods workflow and a condition comparison). Use only numbers from the paper, build the charts as editable PowerPoint charts and put the full citation and DOI in the footer.” Then check every number against the paper, as in Section 4. Route B: Canva Search for "research poster" templates, set the custom size (for example 841 × 1189 mm), and use the AI features to rewrite or resize text. Upload figures as SVG or 300-DPI PNG. When you download, choose PDF Print, not PDF Standard, for the best quality. Route C: an HTML poster made by Claude (the template in this guide) Watch this route in action in my live session on making posters and slides with Claude Code. This route gives you full control, exact sizes and a file you can version on GitHub. Ask Claude for the poster with this prompt, or start from my tested template below: Prompt 5: generate an A0 poster as an HTML fileCopy templateCreate a print-ready conference poster as a single HTML file. - Page size: A0 portrait. Use CSS @page { size: 841mm 1189mm; margin: 0 } and set the body to exactly 841mm x 1189mm. - Layout: a coloured title band (title, authors, affiliations, a logo box), a full-width "main finding" banner, three columns of sections, and a footer with references on the left and a QR code ( ) on the right. - Font sizes in pt: title 90-100, section headings 55-60, body 36-40, captions 24-28.

Main finding: biochar + compost raised grain yield from 3.1 to 4.4 t/ha in a two-season field trial.

Background Degraded soils limit wheat yields for millions of farmers.

Biochar improves water and nutrient retention, but field evidence is mixed.

Question Does biochar, alone or with compost, increase wheat yield under farmer conditions?

Methods 16 field plots, loam soil ▼ 4 treatments × 4 replicates ▼ 2 seasons (2024–2026) ▼ Yield + soil tests Design: randomised complete blocks.

Statistics: one-way ANOVA with Tukey test (p &lt; 0.05).

Results Fig. 1. Grain yield (mean ± SE, n = 4). +42% biochar + compost +29% biochar 10 t/ha +16% biochar 5 t/ha 2 / 2 seasons with the same ranking All yield gains are relative to the control (3.1 t/ha). Every biochar treatment differed from the control (p &lt; 0.05).

Conclusions Combining biochar with compost gave the highest yield. The effect was consistent across both seasons. Next: cost-benefit analysis and on-farm trials. Fig. 2. Yield in each season (n = 4 per treatment). Why it matters A low-cost way to restore degraded farmland and raise food production.

Quick answerCreate a public GitHub repository (for example conference-poster), upload poster.pdf and an index.html page, and turn on GitHub Pages in Settings → Pages (deploy from the main branch, root folder). Your PDF is then online at https://your-username.github.io/conference-poster/poster.pdf. Make a static QR code for that address with high error correction, put it on the poster at least 10 cm wide, and test it. Because the address never changes, you can update the PDF later without reprinting. Why GitHub Pages instead of a file-sharing link? The address is short, permanent and yours. You can replace the PDF with a corrected version and the printed QR code still works. It is free for public repositories, and it doubles as a mini website for your poster with your contact details. Option 1: in the browser (no coding)

Create a free account on github.com if you do not have one. Create a new repository: click New, name it conference-poster, choose Public, tick Add a README, and create it. Upload your files: Add file → Upload files, then drag in poster.pdf, index.html and poster-preview.png. Click Commit changes. (The browser upload limit is 25 MB per file.) Turn on Pages: Settings → Pages, under Build and deployment choose Deploy from a branch, select main and / (root), and click Save. Wait a few minutes, then open https://your-username.github.io/conference-poster/. The PDF is at .../conference-poster/poster.pdf.

Option 2: with git on your computer TerminalCopygit clone https://github.com/your-username/conference-poster.git cd conference-poster cp ~/Desktop/poster.pdf ~/Desktop/poster-preview.png ~/Desktop/index.html . git add . git commit -m "Add conference poster PDF" git push # then enable Settings → Pages once, as in Option 1 The landing page is a small HTML file that shows a preview, a download button and your email, so people who scan the code see something friendly on their phone: index.htmlCopy Poster: Biochar and compost increase wheat yield body { font-family: system-ui, sans-serif; max-width: 760px; margin: 0 auto; padding: 24px 16px; line-height: 1.6; color: #14182B; } a.btn { display: inline-block; background: #0072B2; color: #fff; padding: 12px 20px; border-radius: 999px; text-decoration: none; font-weight: 700; } img { width: 100%; height: auto; border: 1px solid #ddd; border-radius: 8px; margin: 16px 0; } Biochar and compost increase wheat yield by 42% on degraded soils Your Name, Co-Author Name · Poster presented at Conference Name 2027, City

Make the QR code Free online generators work, but many "dynamic" QR services redirect through their own servers and may expire or ask for payment later. A static QR code that you make yourself points straight to your GitHub Pages address and works forever: make_qr.pyCopy# make_qr.py: create a print-ready QR code that points to your poster PDF # pip install "qrcode[pil]" import sys

import qrcode import qrcode.image.svg

URL = sys.argv[1] if len(sys.argv) > 1 else "https://your-username.github.io/conference-poster/poster.pdf"

def make(url: str, name: str = "qr") -> None: qr = qrcode.QRCode( error_correction=qrcode.constants.ERROR_CORRECT_H, # still scans if up to ~30% is damaged box_size=20, # pixels per module in the PNG border=4, # the white "quiet zone" (4 modules is the standard) ) qr.add_data(url) qr.make(fit=True) qr.make_image(fill_color="black", back_color="white").save(f"{name}.png") # for PowerPoint/Canva qr.make_image(image_factory=qrcode.image.svg.SvgPathImage).save(f"{name}.svg") # vector: sharp at any size print(f"Saved {name}.png and {name}.svg for {url} (version {qr.version}, {qr.modules_count}x{qr.modules_count} modules)")

if __name__ == "__main__": make(URL) TerminalCopypip install "qrcode[pil]" python make_qr.py "https://your-username.github.io/conference-poster/poster.pdf" Result: qr.png for PowerPoint or Canva and qr.svg, a vector file that stays sharp at any print size. For the example address, the code is a version 7 QR code (45 × 45 modules), and a decoder read it correctly both from the file and from the full poster image. QR code rules for posters

Size: at least 10 cm wide on A0, ideally 12–15 cm. A common rule is scanning distance ÷ 10, so 1.5 m needs about 15 cm Quiet zone: keep the white border (four modules, as in the QR code standard from DENSO WAVE); do not place it on a busy background Contrast: dark code on a light background; do not invert the colours Label it: "Scan for the PDF" or "Scan for data and code" so people know what they get Test it: scan the screen, then an A4 test print, with two different phones (iPhone and Android) Link to something useful: the PDF, your paper, a dataset, your GitHub code, or your profile page

Privacy: a public GitHub repository is visible to everyone. Only upload the poster if the results are ready to be public; for unpublished data, check with your supervisor, or link to a page that only shows the abstract and your email. Key takeawaysGitHub Pages gives a free, permanent address for your PDF.Same file name = updated PDF, same QR code.Make static QR codes at level H and test them on two phones. ↑ Back to topNext: Step 7: print-ready PDF → Section 8Step 7: how do you export a print-ready PDF? Quick answerExport one PDF page at the exact poster size, with fonts embedded and images at 150–300 DPI at final size. From PowerPoint use File → Export → PDF with the best (print) quality; from Canva use PDF Print; from an HTML poster use Chrome's print to PDF with margins set to none, or the headless command below. Then check the page size, zoom to 100% to inspect sharpness, and print an A4 test copy at 25%. For the HTML template, Chrome reads the @page size and creates an exact A0 PDF. You can use the print dialog (Destination: Save as PDF, Margins: None, tick Background graphics) or one command: Terminal (macOS; on Windows use the path to chrome.exe)Copy# print-ready PDF at the exact @page size "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" --headless=new \ --no-pdf-header-footer --print-to-pdf=poster.pdf "file://$PWD/poster.html"

# PNG preview for your landing page, LinkedIn or the conference app "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" --headless=new \ --hide-scrollbars --window-size=3179,4494 --screenshot=poster-preview.png "file://$PWD/poster.html" Result: a one-page PDF of 841 × 1189 mm (2384 × 3370 points), which is exactly A0. The window size 3179 × 4494 pixels is A0 at the browser's 96 pixels per inch, so the screenshot shows the whole poster. Print-ready checklist

One page, exact size and orientation (check in your PDF viewer's document properties) Fonts embedded (PowerPoint and Chrome do this by default; avoid unusual fonts) Figures sharp at 100% zoom; no blurry screenshots or pixelated logos No important content within 2 cm of the edge; add 3–5 mm bleed only if your printer asks for it Colours: bright screen colours may print duller; ask for a proof if colour matters File size: usually under 50 MB; very large files slow down printing and uploads A4 test print at 25% scale (A4 is exactly a quarter of the width of A0): if the body text is readable, the poster is readable

Keep three files: poster.pdf (print and QR link), poster-preview.png (social media, landing page, e-poster systems) and your source file (.pptx, Canva link or poster.html). You will need all three after the conference. Key takeawaysOne page, exact size, fonts embedded.Check at 100% zoom and with an A4 test print at 25%.Keep the PDF, a PNG preview and the source file. ↑ Back to topNext: Step 8: print and archive → Section 9Step 8: how do you print your poster and save every version? Quick answerPrint on matte or satin paper for the sharpest result, or on fabric if you are flying because it folds into a suitcase without creasing. Order at least one week before travel from your university print shop, a local printer or an online service, and check a proof. After the conference, archive the final PDF with a free DOI on Zenodo, keep the source files and a photo of the printed poster in your GitHub repository, and add the poster to your CV and profiles.

OptionProsCons

Matte or satin paperSharp, cheap, no glare under lightsNeeds a poster tube; creases easily Glossy paperVivid colours and photosReflections under conference lights FabricFolds into luggage, light, reusableCosts more; colours slightly softer Print at the venueNothing to carryHigher price, little time to fix mistakes

Printing checklist

Ask for quotes from two printers with the exact size, material and finish; prices vary a lot by city and service. Send the PDF, not the PowerPoint file, so nothing moves or changes font. Check the proof: size, colours, QR code position and spelling of names. Pack it well: a hard tube for paper, a folder or bag for fabric, plus pins or tape, and a digital copy on your phone. Print extras: 10–20 A4 handouts of the poster or business cards with the same QR code.

Save the printed version: your poster archive

Final PDF with a DOI: upload to Zenodo (free; choose the resource type "Poster", see the Zenodo upload guide), Figshare or OSF, and cite it as a conference poster GitHub repository: keep poster.pdf, poster-preview.png, the source file, the figure scripts and a README.md with the citation Photo of you with the printed poster: great for LinkedIn, your website and reports to your funder Version names: keep poster.pdf as the live file the QR code opens, and save dated copies such as poster-2027-05-printed.pdf Profiles and CV: add the poster with its DOI to your CV, Google Scholar, ResearchGate and LinkedIn

Posters count on applications for PhD positions, postdocs and scholarships.

Key takeawaysPaper for sharpness, fabric for travel.Order a week early and check a proof.Archive the final PDF with a DOI and keep the sources on GitHub. ↑ Back to topNext: Step 9: present your poster → Section 10Step 9: how do you present your poster, and what are the AI rules? Quick answerPrepare a 30-second pitch and a 2-minute walkthrough that start with your main finding, point to your figures while you talk, ask visitors about their own work, and offer the QR code or an A4 copy. Use AI to practise likely questions, but present only what you can explain yourself. Follow the conference and institutional AI policies, verify every claim, keep data and result images real, and disclose AI assistance when asked. Prompt 7: your pitch and likely questionsCopy templateUsing my poster text, write (1) a 30-second "elevator pitch" and (2) a 2-minute walkthrough I can say at the poster, in simple spoken English. Then list five questions visitors or judges are likely to ask, with a short honest answer for each based only on my results. At the poster

Stand beside the poster, not in front of it, and greet people who stop Start with the finding: "We found that ..." rather than "So, the background is ..." Ask "What do you work on?" to tailor your explanation Point to the QR code: "You can scan this for the full PDF and my email" Collect contacts: a notebook or LinkedIn QR code for follow-ups Send a short follow-up email after the conference with the poster link

Ethics and AI checklist

DoDo not

Use AI to shorten, structure and polish textLet AI invent results, numbers or references Use AI to write plotting code you run on real dataGenerate or edit result images with AI Use AI images for icons and illustrationsUse images you have no right to use Check your institution's rules before uploading unpublished data to AI toolsUpload confidential or patient data to public AI services Disclose AI assistance when the conference asksPresent claims you cannot explain yourself
