Gamma
Gamma turns a rough outline or prompt into a formatted slide deck, document, or webpage. For a solopreneur who needs a client pitch deck by tomorrow and doesn't have time to fight with PowerPoint alignment, it's a genuine time saver.
Gamma generates presentations, documents, and websites from the same AI engine and editor (shown above). Most competitors specialize in a single format, so you'd normally need separate tools for a deck versus a landing page.

- Free — 400 AI credits, granted once at signup, do not refresh; enough for roughly 10 full presentations depending on complexity
- Plus — $8/month billed annually ($10/month monthly)
- Pro — $15/month billed annually ($20/month monthly); 4,000 monthly credits
- Ultra — around $90/month; 20,000 monthly credits
The credit math isn't fixed
Credit cost varies by the model and task involved, so a stated credit allowance isn't a guaranteed number of finished decks — a text-heavy deck costs less than one full of AI-generated images. If you're testing on the free plan, know that those 400 credits are a one-time grant, not a monthly reset, which changes how you should budget your first month of use.
Pros
- Fastest way to go from bullet points to a presentable deck on this list
- Output also works as a one-page website or document, not just slides
- Plus tier is cheap enough to justify for occasional use
Cons
- Free credits never refresh — a real trap if you plan to trial it over a few months
- Heavy image generation burns credits fast and unpredictably
- Design customization is more limited than building from scratch in a real slide tool
