The free AI PPT maker that's actually free.
No login. No watermark. No subscription, ever. Unlimited AI presentations, completely free — while everyone else charges $20/month and slaps a logo on your slides.
Prompt to PPT, text to slides, PDF to PowerPoint — supported by a few discreet ads so the tool stays $0 for you, forever.
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.
The honest Gamma, Tome and SlidesAI alternative
They all promise "free", then watermark your decks and push a $20/month subscription. SlideGen does what they pretend to do: a real free plan, no watermark, unlimited decks — funded by a few discreet ads instead of your wallet.

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 — completely. There is no subscription, no credit card, no watermark and no per-deck cap. SlideGen is supported by a few discreet ads so it stays free for everyone, forever.
How does SlideGen stay free if everyone else charges $20/month?+
It runs on advertising revenue (AdSense). You'll see a few unobtrusive ads between sections and, occasionally, a short rewarded ad that unlocks 24 hours of unrestricted use. Your decks themselves never contain ads or watermarks.
Do I need an account?+
No account is required to try most tools. A free sign-in is only needed when you want to save decks to your library, share them publicly via /d/[id] links, or sync usage across devices.
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.
Can the AI build an investor pitch deck?+
Yes. SlideGen has a dedicated AI pitch deck generator that builds the YC/Sequoia-style 10–14 slide deck from a single paragraph.
Does it work for students and teachers?+
Yes. SlideGen calibrates tone and density to your education level — middle school, high school, college and graduate.
