Ranked by evidence — GitHub stars, Hacker News mentions, release activity and how much you can use for free. Recomputed nightly. How the score works.
+ Works inside the Office apps you already use, drafting Outlook replies, summarizing Teams meetings and turning Word docs into PowerPoint decks.
− Results inside Excel and PowerPoint are often shallow compared with the standalone chat, which makes the $30 business seat hard to justify.
+ 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.
+ 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.
+ Generates a full deck or social campaign and then lets you edit every element in the familiar Canva editor.
− AI output leans on Canva's template look, and the most useful Magic features need a Pro subscription.
+ Smart slides enforce design rules so a non-designer cannot make an ugly slide.
− Those same constraints frustrate people who want pixel-level control, and there is no free plan.
