Gamma

Gamma turns a written prompt or an outline into a presentation, document, or simple webpage, generating both the content structure and a matching visual layout in one step rather than requiring a separate design pass after the text is written. That combination (content generation plus layout) is the main thing that separates it from pairing a chat assistant with a traditional slide tool, since the layout and the wording are produced together and stay in sync as either one changes.

The free tier grants 400 AI credits at signup, and those credits do not refill on a schedule; once they're used, the only ways to get more are referring other users (200 credits per referral, capped) or upgrading to a paid plan. That structure makes the free tier a fixed trial allotment rather than an ongoing free tier in the way a monthly-refresh free plan works, which matters when estimating how many decks or documents can actually be produced before a subscription becomes necessary.

Plus, at $8/month billed annually (or $10/month billed monthly), removes Gamma's own branding from generated output and adds unlimited AI generation along with access to more advanced image models, which is the point where the free tier's credit ceiling stops being a constraint. Pro, at $15/month billed annually (or $20/month billed monthly), adds premium AI models, custom branding, usage analytics, API access, and up to ten custom domains, aimed more at teams publishing Gamma-built pages or decks as a recurring, branded output rather than at one-off internal presentations. Ultra raises the credit ceiling further (20,000 monthly credits), supports larger generations (up to 75 cards per prompt), and adds early access to newer text, image, and video model updates.

For someone deciding between tiers, the practical signal is usage pattern rather than feature checklist: a single user putting together an occasional pitch deck rarely needs more than the free credit allotment or, at most, Plus. A team publishing decks or web pages regularly, where unremovable Gamma branding or a hard credit ceiling would actually block real output, is the segment Pro and Ultra are priced for.

For teams comparing Gamma against a conventional slide editor (manually building each slide) or against a general chat assistant asked to draft an outline, the specific advantage shows up in iteration speed: editing the outline regenerates the layout automatically instead of requiring the layout to be rebuilt slide by slide after every content change, which matters most for decks that go through several rounds of revision before a final version, where rebuilding a slide deck by hand after each edit would otherwise eat most of the time saved by generating it in the first place.

Team and Business plans move to custom, sales-quoted pricing, which is typical for the point where an organization needs centralized billing and shared workspace access rather than one more individual seat.

Refunds are only available within the first three days of a subscription, and only below a small per-plan credit-usage threshold, which is worth checking before committing to an annual plan rather than assuming a standard trial-cancellation window applies.
