Gamma vs Decktopus (2026): AI decks from a prompt or branded decks with practice mode?
Gamma turns a prompt or a document into a polished deck, website or document, with a free tier that gives 400 one-time AI credits. Decktopus also builds decks from a prompt, with auto-branding and a Loop practice mode for rehearsing your delivery.
| Gamma | Decktopus | |
|---|---|---|
| Free tier | Free plan with 400 one-time signup credits; up to 10 cards per prompt; exports to PDF, PPTX and PNG | First deck free, but it cannot be exported and carries a Decktopus watermark |
| Paid tier | Paid plans from around $10 a month; check current pricing | Pro from around $10-$15 a month depending on billing; check current pricing |
| Best for | Quick decks, websites and documents from a single prompt | Sales and pitch decks with consistent branding and rehearsal |
| Standout strength | A genuinely usable free tier with exports included, and decks that also work as web pages | Auto-branding plus a practice mode that times and coaches your delivery |
| Watch out for | The 400 free credits do not refill, so heavy users hit the paywall fast | The free deck is a trial only — no export means no finished deliverable without paying |
Gamma wins for most people: the free tier actually lets you finish and export a deck, and the same prompt can become a deck, a document or a web page. Decktopus wins when the deck is a sales tool — its auto-branding keeps every slide on brand, and the Loop practice mode is the kind of feature you only miss when you are about to present.
Start with Gamma's free credits and see how far they take you. If you present to clients every week and want branding plus rehearsal built in, Decktopus is worth the paid plan — just do not expect its free deck to be a finished deliverable.
