What it is
PPTAI (pptai.pro) is a free AI presentation maker: you give a topic, slide count and style, and it generates a downloadable, editable PowerPoint (.pptx). It's ad-supported and available in several languages (e.g., English and Korean versions).
Key features
- Topic-to-deck with chosen slide count and style.
- Editable .pptx download for PowerPoint or Google Slides.
- No subscription or sign-up (per the site and a third-party test).
- Generation typically under two minutes.
How to use it
- Open pptai.pro (choose your language).
- Enter topic, number of slides and style.
- Generate, review, download the .pptx and edit in PowerPoint.
Pricing
Free; the site advertises no subscription fees or hidden costs and shows ads. (No pricing page; /pricing returns 404.)
Use cases
- Class presentations: generate 8–12 slides on a topic, then add your own sources and images.
- Quick internal updates: a structured draft to paste into your company template.
- Non-English decks: the site is offered in several languages (e.g., Korean).
What to check before presenting
AI-generated slides can contain generic or outdated statements. Verify facts and numbers, replace stock imagery where needed, and adjust fonts and colours to your template after opening the .pptx in PowerPoint or Google Slides.
How to write a better prompt
Give PPTAI the topic, audience, number of slides and the key points you need covered — for example, "10 slides for first-year students on renewable energy, include one slide on costs and one on careers." The more specific the brief, the less generic the outline. Generate, review the outline and regenerate sections that miss the mark before polishing in PowerPoint.
Pros & cons
Pros
- Free with no account.
- Standard .pptx output.
Cons
- Topic-only input — no document or URL import found.
- Ads on the site; limited information about the operator and data handling.
- Fewer editing tools than paid generators.
Best for
Students and anyone needing a quick free first draft of slides.
Alternatives
| Tool | Choose it instead if… |
|---|---|
| Smallppt | You need to build slides from PDFs, Word files or URLs (paid for unlimited). |
| Claude | You want a stronger outline and speaker notes. |
| Gemini | You use Google Slides and want AI help inside Google's ecosystem. |
| Beautiful.ai (not on AI Jet) | You want auto-formatting design rules for business decks. |
| Gamma (not on AI Jet) | You present on the web rather than in PowerPoint. |
| Canva (not on AI Jet) | Visual design and templates matter more than AI writing. |
Verdict
Good for a free, fast first draft; for document-based decks or polished design, use a paid tool.
