What we tested
We gave each tool the same prompt — 'Create a 10-slide pitch deck for a sustainable coffee subscription startup' — then judged speed to first draft, slide design quality, editability, and whether the export actually opened cleanly in Microsoft PowerPoint.
1. Gamma — Best overall free AI deck builder
Gamma generates a full, well-designed deck in under a minute from a single prompt. Layouts adapt to content (no awkward giant title slides), images are auto-sourced, and the PPTX export opens cleanly in PowerPoint and Keynote. Free plan gives you 400 AI credits, enough for 5-10 decks.
2. Canva — Best if you already use Canva
Canva's Magic Design for Presentations turns a prompt into a 10-slide deck using its template library. Slides look polished out of the box and the brand kit keeps fonts and colours consistent. Free plan covers most needs; PPTX export works on the free tier.
3. Beautiful.ai — Best for design-first decks
Beautiful.ai's 'DesignerBot' generates decks that look like a real designer touched them. The free 14-day trial is enough to ship 1-2 important decks. Best pick when slide aesthetics matter more than speed.
4. Tome — Best for narrative-style decks
Tome produces narrative, scroll-friendly presentations more than traditional bullet decks. Great for portfolios, product walkthroughs, and pitches that don't need to look like a McKinsey slide. Free plan is generous.
5. ChatGPT + a free PowerPoint template — Most flexible
Ask ChatGPT (or Gemini) to outline a 10-slide deck with speaker notes, then paste each slide into a free PowerPoint template from Microsoft Create or SlidesCarnival. Slowest but you keep 100% control and zero credit limits.
Our pick
For most people in 2026: Gamma. Fastest from prompt to polished, editable PowerPoint. Use Canva if you already pay for Canva Pro; use ChatGPT + template if you want full control with no credits to worry about.
Frequently asked questions
Is there a free AI tool that exports to .pptx?
Yes — Gamma, Canva, and Beautiful.ai all export to .pptx on their free or trial tiers, and the files open cleanly in Microsoft PowerPoint and Keynote.
Can ChatGPT create a PowerPoint directly?
Not natively as a .pptx file. It can generate slide content, outlines, and speaker notes — you then paste them into a template, or use a GPT in the ChatGPT store that wraps the output in a PPTX file.
What's the best free AI tool for pitch decks?
Gamma for speed and polish, Beautiful.ai for design quality, Tome for narrative-style decks. All three offer free plans large enough for a real pitch deck.
Will AI-generated slides look generic?
Less than you'd think in 2026 — but always swap stock images for your own, rewrite the headlines in your voice, and tweak one or two layouts so it doesn't look like the default template.
