Plus AI vs SlidesAI
Someone stuck making slides inside Google Slides or PowerPoint wants an AI add-in without switching tools, and is deciding between one built for teams already on those platforms and one aimed at fast first drafts inside Google Workspace specifically.
The difference that matters
Plus AI has no free tier at all, only a 7-day trial requiring a card, starting at $10/user/month billed annually ($15/month billed monthly), built for teams stuck on Slides or PowerPoint who want AI without leaving the file format, though it works inside your existing template so an ugly deck stays ugly, just faster. SlidesAI keeps a real free tier (12 AI-generated presentations/year, 1,000-character input per presentation, 120 AI credits/year) and its Pro tier is the same $10/month (or $120/year, $8.33/mo effective), built specifically for Google Slides users, teachers, and students wanting a fast first-draft deck without leaving Google Workspace, though it's the wrong choice for polished agency-grade visual design or anyone outside Google Slides.
Side by side
| Plus AI | SlidesAI | |
|---|---|---|
| Free tier | None (7-day trial, card required) | Yes: 12 AI-generated presentations per year, 1,000-character input per presentation, 120 AI credits/year |
| Entry paid plan | $10/user/mo (billed annually), $15 billed monthly | $10/mo billed monthly, or $120/yr ($8.33/mo effective) |
Choose Plus AI if
You work across both PowerPoint and Google Slides and want a paid add-in without a free tier limiting you first.
Choose SlidesAI if
You're specifically in Google Slides, want a genuine free tier to test with first, and mainly need fast first drafts, not polished design.
Our verdict
Plus AI wins for teams that need PowerPoint support alongside Slides. SlidesAI wins for Google Slides-only users who want to try free first, and it matches or undercuts Plus AI's price at every billing cycle ($10/mo, or $8.33/mo effective annually, versus Plus AI's $15/mo or $10/mo annual).
What to watch out for
Plus AI's $10/user/mo (annual) / $15/mo (monthly) pricing with no free tier (7-day trial only) is confirmed on its own pricing page. SlidesAI's free tier (12 presentations/year, 1,000-character input, 120 AI credits/year) and $10/mo ($120/yr) Pro tier are confirmed via a direct fetch of its pricing page.
