Free AI PPT Maker — No Login, No Watermark
The truly free AI PPT maker. Generate professional presentations from any prompt without signup, without watermark and without a trial paywall.

Unlike most "free trial" tools that lock exports behind a paywall, SlideGen lets you generate, preview and download presentations on the free plan — no signup needed to try, no watermark on free decks, no credit card. Use it as a free Gamma AI alternative, a free SlidesAI alternative or a free Tome alternative. Power users can unlock unlimited presentations forever with a single $5 Lifetime license — no subscription, ever.
Why SlideGen
What you get on the Free plan
The free plan is built to be useful, not a teaser. It gives you 5 free AI presentations to actually finish real work — homework, side projects, internal updates, lightning talks — with full export and AI design.
- 5 AI presentations to start
- Full PPT / HTML export
- Professional templates
- AI-written speaker notes
- No watermark on free decks
- Works on web, mobile, tablet — no app install
When should I upgrade?
Most users never need to. If you do, there's only one upgrade — and it's $5. The Lifetime license is a single one-time payment that unlocks unlimited AI presentations forever. No subscription, no renewals, no upsells.
- Lifetime: $5 one-time payment
- Unlimited AI presentations, forever
- All premium templates + priority queue
How is this different from Gamma AI free / SlidesAI free?
Most competitors offer a 'free trial' rather than a real free plan — exports are blocked, watermarks are added, or generations are capped at 1 or 2. SlideGen's free plan is meant to be used. You only run into limits if you create at high volume.
