How to make a presentation with AI

Short answer: choose a tool that matches where the deck will live (Gamma for decks shared online, Plus AI for Google Slides and PowerPoint, Canva on a budget), give it your source document or a detailed outline, then edit the story first, the design second and the numbers last.

Step 1: pick the right tool for where the deck ends up

• Shared as a link: Gamma makes fast, modern decks designed to be read online. It has a free plan with 400 one-time credits.
• Must end up in PowerPoint or Google Slides: Plus AI works inside the tools you already use.
• Strict brand rules: Beautiful.ai keeps every slide on-brand with smart templates.
• Tight budget: Canva has a free plan with AI credits, and covers social graphics and documents too.
• Your company runs on Microsoft 365: Microsoft 365 Copilot turns Word documents and PDFs into draft decks.

Step 2: start from content, not a one-line prompt

"Make a deck about our Q3 results" gives you generic slides. The best decks start from something real: a report, a memo, meeting notes or a rough outline. Most tools let you paste or upload a document and build slides from it.

If you start from a prompt, include the audience, the goal, the number of slides and the key points:

Step 3: fix the story before the design

AI drafts often have too many slides and too many words. Before touching colors, read only the slide titles in order. They should tell the whole story on their own. Merge repeated slides, cut filler, and make each title a sentence that states the point, such as "No-shows cost a typical restaurant two tables a night", not "The problem".

Step 4: check every number and claim

AI can invent figures that look plausible. Replace every statistic with one you can source, and check names, dates and prices. For data-heavy professional decks, think-cell is the specialist for accurate, editable charts.

Step 5: polish the design

• Apply your brand colors and fonts once, through the theme, rather than slide by slide.
• Keep one idea per slide and aim for a few words per line.
• Replace stock-looking images with your own product screenshots or photos where you can.
• Make sure text is readable from the back of the room.

Step 6: rehearse with speaker notes

Ask the tool to draft speaker notes for each slide, then rewrite them in your own words. Presenting from notes you understand is what makes an AI-made deck sound like you.

Mistakes to avoid

• Presenting the first draft without editing it.
• Trusting AI-generated statistics.
• Choosing a web-first tool when your company requires PowerPoint files.
• Paying before you test the export format you need.
