Gamma vs Plus AI
Gamma scores 25 to Plus AI's 15 on public evidence for slides & presentations, and they rank #2 and #3 there. Only Gamma has a free tier. Numbers below are the same public signals the ranking uses, recomputed nightly — nothing here is sponsored.
Gamma
Generates presentations, documents and web pages from a prompt or outline with a card-based layout engine.
+ The best-looking AI-generated decks with the least fiddling, and it exports to PowerPoint and PDF.
− Exports lose some formatting, and the free tier watermarks and limits AI credits.
Plus AI
An add-on that generates and edits slides directly inside Google Slides and PowerPoint.
+ Decks are native Google Slides or PowerPoint files from the start, so there is nothing to export or convert.
− Only a free trial, and the generated layouts are plainer than Gamma's.
