Gamma vs SlidesAI
Gamma (free 400 one-time credits; Plus $9/person/month annual; Pro $18/month annual, Oct 2026 official figures) is web card-style presentations, strong on shareable online links and presentation display, with PPTX export as an add-on; SlidesAI is a native Google Slides/PowerPoint plugin, strong in landing the final file in your familiar editor. Online sharing with good-looking links pick Gamma; must deliver editable PPTX files to clients or teachers pick SlidesAI. Gamma's free credits don't renew; SlidesAI's free Basic gives 12 decks per year.
| Decision point | Gamma | SlidesAI |
|---|---|---|
| Best suited to | Structuring a first presentation draft from source notes, then revising the story and exporting a file for review. | Turning an outline or notes into a first slide structure, then refining the result in Google Slides and downloading a deck. |
| Plans and cost | Free starts with 400 credits that do not refresh or expire, and the pricing page lists up to 10 cards per prompt. Paid Plus, Pro and Ultra tiers offer monthly and annual billing; a current paid amount is not confirmed here. Check the billing period, currency and total charge on the plan you choose. | The pricing page lists Basic at $0 with 12 presentations/year, Pro at $10/month billed $120/year, and Premium at $20.83/month billed $250/year. It also displays plan-specific presentation, character, and AI-credit limits. Prices use $ without an explicit currency code; verify the current allowance and billing total on the plan page. |
| Limitations | Free use has a one-time credit pool and watermarked exports; a live Gamma link is not the same deliverable as a PowerPoint file. | The free tier caps annual presentations and text length; AI editing uses a separate credit allowance, and export is a file step rather than a share link. |
