Gamma review

Gamma review cover graphic

Gamma is an AI tool for generating presentations and similar content from a prompt. You describe what you want, Gamma produces a set of cards (its word for slides), and you edit the result by hand or with further AI help. Over the past year the more interesting story has been its pricing, which moved from unlimited AI generation to a credit system in October 2025.

This review explains what Gamma is, how credits and plans work according to its own help centre, what the free plan does and does not include, how refunds work, and what we could not confirm. Because credit rules drive the real cost, we spend most of our time there.

How we researched this: we did not run hands-on tests for this article. It is based on the vendor’s own documentation and public sources, checked on 11 November 2026. Features and prices change, so confirm details on the vendor’s site before you buy.

Key takeaways

  • Gamma moved from unlimited AI generation to a hybrid model in October 2025: a subscription plus credits for advanced AI. Longer or more complex generations use more credits.
  • The help centre lists monthly credits of 1,500 on Plus, 4,000 on Pro and 20,000 on Ultra. New Free users get 400 credits once, and those do not refresh.
  • Manual edits such as typing, rearranging and choosing a theme are free. Failed AI actions and clarifying questions are not charged.
  • Refunds are available only in the first 3 days, and only if credit use stays under a plan-specific threshold.
  • Gamma’s own pages disagree on some plan limits, so confirm card limits and token limits on the live pricing page before you rely on them.

What it is

Gamma’s documentation describes content built from cards, with a limit on how many cards a single prompt can generate. The free plan description on its pricing page mentions unlimited gammas and users, import and export to PPT and PDF, and a website builder that was labelled as beta when we looked. Gamma also publishes an API and an MCP server, and its developer documentation says connectors exist for ChatGPT, Claude and Slack.

The most useful thing to understand is what an AI action means in Gamma. The help centre says AI actions include Create with AI or with the Agent, editing with the Agent, adding cards with AI, trying new layouts, and generating or editing AI images. These consume credits. Doing the same work by hand does not.

A change in pricing model

Gamma announced on 30 September 2025 that it was evolving its pricing, with the new model starting in October 2025. The company said advanced AI models are expensive to run, that unlimited usage made offering the top models unfeasible, and that it wanted to support more powerful models and large-scale automation without raising subscription prices for everyone. It said more than 90% of users would not notice a difference. That is the company’s own claim, and we cannot verify it.

Who it is for

Gamma’s plans are built per seat. Individuals use Free, Plus, Pro or Ultra. Team and Business plans exist for workspaces, and the help centre says Business credits are shared at workspace level and that Enterprise workspaces get credits through their account team. The developer documentation indicates API keys are available on all plans, including Free, with credits applying on every plan, so developers can try it without paying first.

In practice, someone who makes decks occasionally and edits them by hand may live comfortably inside a small credit allowance. Someone who generates many long decks with AI images could use credits quickly. Use the live credit counter when you test, not a guess.

Key features (documented)

The table brings together limits stated on Gamma’s help centre and developer documentation. Where Gamma’s own pages disagree, we note it.

Plan Monthly credits (help centre) Extras the help centre lists
Free 400 on sign-up, no refresh Up to 10 slides per prompt, basic image models, 50k input tokens for initial generation
Plus 1,500 Removes the Gamma badge; basic and advanced image models; up to 100 slides per prompt; 100k input tokens
Pro 4,000 API access, 10 custom domains, detailed analytics, headers and footers, password protection, premium image models
Ultra 20,000 API access, 100 custom domains, custom fonts, Ultra image models, early access to new features
Business Not covered in the article we read See Gamma’s separate Business article

Where Gamma’s pages disagree

The pricing page snapshot we could read described Free as 20,000 AI token inputs and Plus as up to 20 cards, while the help centre article on upgrading says Free has 50k input tokens and Plus allows up to 100 slides per prompt. The developer documentation says cards per gamma are up to 10 on Free and up to 100 on Plus and above, which matches the help centre. One of these pages may be out of date. When limits matter to you, check the live pricing page and ask support to confirm.

API and agent features

The developer documentation says standard generations are priced per card and per image. Cards cost 1 to 3 credits each depending on the text model Gamma selects. Images cost 2 to 15 credits for Standard, 20 to 33 for Advanced, 34 to 75 for Premium and 30 to 125 for Ultra, per image. Agent generations and edits are priced by the work the agent does, using a quality preset, and the same prompt can cost different amounts across runs. The agent quality “max” requires Pro or higher, and analytics endpoints are not available on Free. Gamma notes that credit rates and billable actions are subject to change.

Pricing model

Gamma sells per-seat subscriptions with a monthly credit allowance, and lets paid users buy more credits. We could not read dollar prices for each plan from an official page, so we do not quote them. The one price we can quote from Gamma’s help centre is for extra credits.

Rule What the help centre says
Credit refill Plan credits refill monthly on your billing date
Rollover Plan credits roll over up to double your plan size; on Plus that is 3,000
Buying credits Paid plans only; purchases start at $6 for 1,500 credits at a flat rate; up to 2,000,000 credits in one purchase
Purchased credits Used after plan credits, do not count toward the rollover cap, and do not expire while your plan is active
Auto-recharge Off by default; admins set the amount and a trigger balance, which defaults to 500
Annual billing Same monthly credits as monthly plans, at a 28% discount
Seats Per user; two users on Pro are billed double
Ultra Currently monthly only
Free trial None; new accounts start on Free with 400 credits

If you cancel

The help centre says cancelling keeps your plan active until the end of the billing period, then returns you to Free. Plan credits reset to the Free allotment of 400, and purchased credits are kept for one year after your plan ends. Referrals can earn Free users extra credits: 200 credits per referral, up to 2,000 held at once.

Refunds

Refunds are available only within the first 3 days of subscribing, and you must contact support in that window. Cancelling does not trigger an automatic refund. Your credit use must stay below a plan-specific threshold: fewer than 300 credits on Plus, 600 on Pro, 900 on Team, 1,000 on Business and 2,000 on Ultra. After three days, refunds are not issued except where applicable law requires one. The help centre says double billing is likely to be from additional workspace members, who are billed per member.

These rules are worth reading closely, and our guide to reading an AI tool’s pricing page explains why credit systems, rollover caps and refund thresholds deserve as much attention as the headline price.

Strengths

  • Manual editing is free. Typing, rearranging, and choosing themes, fonts and colours do not use credits, and you can keep editing by hand after you run out.
  • Fair handling of failures. You are not charged when an AI action fails, shows an error or asks a clarifying question.
  • Detailed credit documentation. The help centre explains buckets, ordering, rollover and expiry, and the developer docs list per-card and per-image costs.
  • A way to try the API. API keys, the MCP server and connectors are available on all plans, including Free.
  • Rollover. Unused plan credits carry over up to twice the monthly amount.

Limits and cautions

  • Credits are hard to forecast. Longer or more complex generations and more advanced models use more credits, so the same prompt can cost differently across runs.
  • The free allowance is one-off. The 400 credits do not refresh, and Free users cannot buy more.
  • Strict refund window. Three days, with credit thresholds, and no free trial to test first.
  • Per-seat billing adds up. Each workspace member is billed, and multi-member individual workspaces can only use auto-recharge for extra credits.
  • Inconsistent published limits. Different Gamma pages give different numbers for some plan limits.
  • Output still needs checking. AI-generated slides can contain errors, so read our guides on how to check AI output for mistakes and AI hallucinations before you present.

Privacy and data

We could not open Gamma’s privacy policy, security page or terms during this research, and the developer documentation we read says nothing on data privacy or retention. We therefore cannot report where data is stored, whether prompts or content are used to train models, or what certifications apply. We also do not know which third-party AI model providers Gamma uses for each action, beyond the fact that its pricing documents refer to text models and image model tiers that Gamma selects.

Privacy question Status in our research
Use of content for AI training We could not confirm
Data location and retention We could not confirm
Security certifications We could not confirm
Password protection for shared content Listed as a Pro feature in the help centre

If your decks contain client or company data, ask Gamma for its data processing terms first, and review how to protect company data when using AI tools.

Alternatives

We did not research specific competitors for this review, so we do not compare named products. The general alternatives are other AI presentation generators, the AI features built into office suites you may already pay for, and building slides by hand using a template. A useful comparison will focus on how each handles credits or usage limits, export quality, and data terms. Our guide on how to compare AI tools side by side fairly gives a method, and how to choose an AI tool covers the first questions to ask.

Option What to compare
Other AI presentation tools Usage limits, export formats, pricing per seat, data terms
Office suite AI features What your existing subscription already includes
Manual templates Time cost versus subscription cost

Who should and should not use it

Best for these people, if these conditions apply

  • You make presentations or documents regularly and want AI to draft the first version.
  • You are happy to edit by hand, which does not use credits.
  • You can monitor credit use, and your usage fits inside a monthly allowance with rollover.

Look elsewhere, or test carefully, if these apply

  • You need predictable monthly costs and generate many long decks with AI images.
  • You need confirmed data protection terms and have not yet seen them in writing.
  • You want a free trial. Gamma documents none, though the Free plan lets you try the basics.

Questions to ask before buying

  1. How many credits does one of my typical decks use, including images?
  2. Which plan has the card limit, token limit and features I need, given the pages disagree?
  3. How many seats do I need, and what will they cost per month?
  4. What are Gamma’s data, training and retention terms for my content?
  5. Would I use the API or agent, and at what quality setting?
  6. Can I finish my test inside the 3-day refund window and the credit threshold?

Use the Free plan to estimate credit use, and follow the checklist in how to test an AI tool before you pay for it.

Frequently asked questions

Is Gamma free?

There is a Free plan. New Free users receive 400 credits when they sign up, and Gamma says these do not refresh. Free credits can be topped up through referrals, at 200 per referral up to 2,000 held at once.

How many credits do paid plans include?

Gamma’s help centre lists 1,500 monthly credits for Plus, 4,000 for Pro and 20,000 for Ultra. Check the live pricing page for current numbers.

Do unused credits roll over?

Plan credits roll over up to double your plan size, according to the help centre. On Plus, that is 3,000.

Can I get a refund?

Only within the first 3 days of subscribing, by contacting support, and only if your credit use stays below the plan threshold, such as fewer than 300 credits on Plus.

Does Gamma have an API?

Yes. The developer documentation says API keys are available on all plans, including Free, and that credits apply on every plan.

Are manual edits charged?

No. The help centre says typing, rearranging and choosing a theme, font or colour are free, and that you can still edit by hand after running out of credits.

Conclusion

Gamma’s documentation is strongest on credits: what uses them, how they roll over, how extra credits work and what refunds require. The main cautions are cost forecasting, a one-off free allowance, a short refund window and some inconsistent published limits. We could not confirm its privacy terms, so get those before you upload sensitive material.

Try one real deck on the Free plan, record the credits used, and then decide whether a paid tier or a different tool makes sense, using how to choose an AI tool as your guide.
