The free AI PPT maker that turns any prompt into a stunning presentation
SlideGen is the AI presentation generator professionals use to ship decks 20× faster. Prompt to PPT, text to slides, PDF to PowerPoint — all online, all free to start, all without watermarks.
Prompt to PPT in seconds
Describe any topic in a single line and SlideGen returns a finished, multi-slide presentation — cover, sections, bullets, charts and a strong closing slide.
Text-to-slides, PDF-to-PPT
Paste an article, drop in a PDF, or convert a Word document. The AI extracts the structure and rebuilds it as a clean, slide-ready deck.
Exports to PowerPoint, Keynote, Google Slides
No vendor lock-in. Download a PowerPoint-compatible file and edit it in PPT, Keynote or Google Slides. Speaker notes included.
AI pitch deck generator
Generate an investor-ready 12-slide pitch deck — problem, solution, market, traction, business model and the ask — from a single paragraph.
Beautiful, modern templates
Every deck uses a consistent design system: clean typography, balanced layouts, AI-picked colours and icons. Looks like a senior designer made it.
Free, no watermark
Most "free" AI presentation makers add watermarks or lock exports. SlideGen's free plan is meant to be used — no credit card, no watermark on your decks.
One AI presentation maker, every use case
SlideGen is the same engine for an MBA case study, a Series A pitch deck, a teacher's lesson plan, a sales QBR or a YC demo day talk. Calibrated to your audience and your stage.
How to make a PPT using AI in 3 steps
- 1
Describe your topic
Type your topic, paste an outline or drop your text. Even a single sentence works — "a 10-slide deck on quantum computing for high schoolers."
- 2
AI builds the deck
SlideGen writes the slide copy, picks layouts, builds charts and applies a clean design system. Speaker notes for every slide are included.
- 3
Edit, download, present
Preview live, download as PPT/HTML, open in PowerPoint, Keynote or Google Slides and present anywhere.
A faster Gamma, Tome and SlidesAI alternative
SlideGen is built for traditional 16:9 decks you present in PowerPoint, Google Slides or Keynote — with a generous free plan, a one-time Lifetime payment option and a Pro subscription for power users.
AI PPT maker — frequently asked questions
How do I make a PPT using AI for free?+
Open SlideGen, type your topic or paste text, click generate. Within seconds the AI builds a multi-slide deck you can preview, edit and download — no signup needed to try.
Can AI create a presentation from a prompt?+
Yes. SlideGen's prompt-to-PPT engine generates a complete deck — cover, sections, bullet points, optional charts and a closing slide — from a single sentence.
How do I generate 10 slides in 1 minute using AI?+
Specify the number in your prompt: "generate 10 slides on …". SlideGen targets that length and finishes in under a minute.
Can I export to PowerPoint, Google Slides or Keynote?+
Yes. Decks export as PPT/HTML and open natively in PowerPoint, Google Slides or Keynote, with speaker notes preserved.
Is SlideGen really a free AI PPT maker?+
Yes. The free plan has no watermark and gives you multiple presentations per month. Upgrade only if you need more decks or premium templates.
How does SlideGen compare to Gamma AI, Tome and SlidesAI?+
SlideGen is faster, free without watermark, and PowerPoint-first. It's the right alternative when you need a real PPT to present anywhere — not a browser-hosted narrative.

Does it work for students and teachers?+
