ChatSlide vs Gamma (2026): which should you pick?

Pick ChatSlide if

• Fits if you want a first draft of a deck from a document
• Works for people who want a deck turned into a narrated video

Look elsewhere if

• Tight if you make many decks, because Plus gives 500 credits a month and Pro 2,500
• Watch out: HIPAA compliance is on request for Ultimate only, and Keynote export and private projects are plan features
• Pricey if you want unlimited credits, as Ultimate is $33.25 a month yearly or $59.90 monthly
• Skip it if you want a desktop or phone app, as none is listed

Pick Gamma if

• Fits if you have notes or an old file and want a first-draft deck out of them
• Works for asking "make slide 4 shorter" rather than dragging boxes around

Look elsewhere if

• Tight if you're never paying, because the 400 free credits don't come back
• Skip it if you want clean exports for free, as PDF and PowerPoint files carry a Gamma badge
• Not for you if you edit on your phone outside the US and Canada, where the apps aren't offered yet
• Watch out: Plus, Pro and Ultra prices aren't on record, and Business is $40 a member a month billed annually
• Pricey if you need the API, viewer analytics, passwords or custom domains, as all start at Pro

• The pricing page also has a Lifetime tab labeled -70%, but its prices were not readable, so it is not recorded.
• Credits are monthly; the page lists 500 on Plus and 2,500 on Pro, and Ultimate is unlimited.
• Keynote export, private projects and HIPAA compliance appear in the feature list; HIPAA is on request for Ultimate only.
• The vendor shows a 14-day refund note and a 40% education discount.

Gamma

• Plus, Pro and Ultra prices are shown only on Gamma's pricing page; its help center gives the Business price, $40 per member per month billed annually.
• Free-plan AI credits do not refresh: accounts start with 400 and earn 200 more per referral. Paid plans get monthly credits, from 1,000 on Plus to 20,000 on Ultra.
• API keys, detailed viewer analytics, password protection and custom domains start at the Pro plan, and Ultra is sold on monthly billing only.
• The mobile apps are in early access, limited to the US and Canada, and edit only through the agent, with no manual editing.
