Gamma

Gamma is the fastest way to go from idea to a polished, shareable deck — and by fast, we mean under 30 seconds for a complete multi-slide presentation with real layout, imagery and typography choices made for you. Paste in a rough outline or a wall of notes and Gamma structures them into slides that genuinely look like a designer touched them. No template-picking, no alignment wrestling, no font pairing decisions. The output works best as a shareable web link — the analytics show you who opened it and how far they got — though it exports cleanly to PowerPoint and PDF when you need to present in a traditional context. Gamma also generates web pages and docs in the same workflow, which is an underrated use case for landing pages and one-pagers.

What most reviews don't mention is how well Gamma handles iteration. Retype your prompt with a different angle, regenerate a single slide, swap the colour theme — the editing loop is fast enough that you can get to a final result in 20 minutes even if the first generation misses the mark. The catch is control: if you have a very specific vision for how individual slides should look, you'll hit friction, because Gamma's layouts aren't as granularly customisable as PowerPoint or Canva. The free tier's 400 AI credits are front-loaded generosity — heavy users will exhaust them in a few sessions and step up to Plus at $10/month.
