Verdict
Gamma builds a full deck from a short description, with layouts and pictures, and Tom's Guide found the slides could be edited or redone one at a time. Free accounts get 400 credits that never refill, and Trustpilot reviews (1.6 from 125) are dominated by billing and refund complaints. individual reviewers say decks start to look alike and PowerPoint exports can break.

Ratings
What people say
People like how fast it produces a decent first draft, but heavy users in user reviews say the output gets samey, exports to PowerPoint break and charts can be wrong. Trustpilot (1.6) is far below Google Play (4.75), with most complaints about renewals and refused refunds.
“Gamma is faster when the input is an outline and you need a coherent, web-style deck without touching every box.”
