Gamma review
AI-native deck generator built around a scrollable card canvas, with the fastest prompt-to-deck workflow of the four tools in this guide and the worst Trustpilot score
Unpaid review. We currently earn nothing if you sign up for Gamma — links here go straight to the vendor. We review it anyway because it's the honest answer, and scores never depend on commissions — how we test.
ToolsGavel verdict
Gamma is the most AI-native tool in this guide: feed it a prompt or a document and it builds the whole deck, with real-time multiplayer editing and a permanent, no-card free plan on top. That's a genuine strength, and it's also where two specific risks sit that any buyer needs to weigh before signing up. Its Trustpilot score, 1.6 out of 5 from 129 directly confirmed reviews, is the worst of any tool checked for this guide, driven almost entirely by billing and refund complaints rather than product-quality gripes. And its native scrollable-card format doesn't convert cleanly to PowerPoint's fixed slide grid, a recurring, well-documented complaint for anyone who needs to deliver a .pptx file rather than share a live Gamma link. If your audience is fine viewing the deck as a web link and you've read the billing terms closely, Gamma's speed is real. If a clean PowerPoint handoff is non-negotiable, test the export before you commit.

Best for: Teams that want the fastest AI-native deck generation and a genuine no-card free plan, and who don't need a clean PowerPoint export
What we liked
- The most AI-native workflow of the four tools in this guide, generating a full deck from either a text prompt or an uploaded document, with no template-browsing step in between (gamma.app)
- Real-time multiplayer co-editing with live cursors and commenting on every paid plan, a stronger built-in collaboration story than Prezi's unverified tier-gating (gamma.app/pricing)
- A permanent free plan with no credit card required, the easiest zero-cost entry point among the three dedicated presentation tools in this guide, since Prezi's free tier is hidden and Canva's AI access on Free is more limited (gamma.app/pricing)
- A modern, visually distinct card-based output that multiple independent reviewers single out as requiring little manual design effort to look finished (G2)
What to watch
- The worst Trustpilot score of any tool in this guide by a wide margin: 1.6 out of 5 from 129 reviews, directly confirmed, with 75% of those reviews one-star and billing or refund complaints as the dominant theme (Trustpilot)
- PPTX export is the single most-repeated technical complaint in Gamma's reviews: converting the native scrollable-card format into PowerPoint's fixed 16:9 slides can break layouts, flatten animations and embeds, and resize images, a real problem for anyone who has to hand a client or a boss a working .pptx file (Trustpilot / independent reviews)
- G2 and Capterra samples are thin, 27 to 39 reviews on G2 and just 4 on Capterra, so those favorable scores are directional rather than statistically solid, unlike Canva's or Prezi's much larger samples (G2 / Capterra)
- AI output can read as generic or repetitive across slides, and several independent reviewers describe it ignoring specific edit instructions without saying so (G2)

Gamma builds a full slide deck, or more precisely a scrollable card-based deck, from a text prompt or an uploaded document, aimed at anyone who wants the fastest route from an idea to a shareable presentation. Pricing runs free forever on a 400-credit entry tier, then $12 to $100 per seat a month across three paid plans ($9 to $90 billed annually), with a monthly AI-credit allowance on top. Gamma’s own Trustpilot page, fetched directly for this review, shows 1.6 out of 5 from 129 reviews, the lowest score of any tool in this guide, while its G2 listing runs closer to 4.0 from a much smaller sample, as of October 2026.
What Gamma is for
Prompt-to-deck generation is the whole product: type a topic or paste a document, and Gamma writes the outline, picks the visuals, and lays out a full deck without a template library to browse first. The output lands on a native card-based canvas, a scrollable format rather than fixed 16:9 slides, which can also be published as a live interactive link instead of a downloaded file. Real-time multiplayer editing, live cursors, autosave and commenting ship on every paid plan, useful for a team iterating on a deck together rather than passing a file back and forth by email.
Export covers PPTX, PDF, PNG and Google Slides on every plan; paid tiers just drop the “Made with Gamma” watermark that Free leaves on every download. The PPTX option is where the native-format tradeoff shows up directly: PowerPoint expects fixed 16:9 slides, Gamma’s canvas doesn’t work that way by default, and the conversion between the two is the single most-repeated technical complaint in Gamma’s reviews, covered in full below.
What you get on each plan
| Plan | Monthly billing | Annual billing (per month) | AI credits/mo | Key gates |
|---|---|---|---|---|
| Free | $0 | $0 | 400 at signup, no refill | Watermarked exports, 10 slides/generation, standard AI model |
| Plus | $12/seat | $9/seat ($108/yr) | 1,500 | No watermark, 100 slides/prompt, advanced AI model |
| Pro | $25/seat | $18/seat ($216/yr) | 4,000 | Unlimited slides/prompt, up to 10 custom domains, premium AI model, shared team brand kit |
| Ultra | $100/seat | $90/seat ($1,080/yr) | 20,000 | Up to 100 custom domains, most advanced AI model |
Credits meter every AI action, not slides directly, and the cost per action shifts with which AI model you’re using and how complex the request is, so a single “generate” click doesn’t burn a fixed number of credits every time. Annual billing cuts the per-seat price by 25% to 28%. Prices come from the vendor pricing page, checked in browser 2026-11-08.
The PPTX export problem
This is the one technical limitation in this review worth slowing down for. Gamma’s native format is a scrollable card canvas, closer to a long webpage than a slide deck, and exporting that to PowerPoint’s fixed-dimension slide grid is a genuine conversion, not a simple file-type swap. Independent reviews describe layouts breaking, animated or embedded content flattening into static images, and images resizing unpredictably once the deck lands in PowerPoint. One Trustpilot reviewer put the core complaint bluntly: Gamma “does not even know how to confine within a PowerPoint slide, overflows.”
None of that makes Gamma a weak tool for every use case; decks meant to be viewed as a live Gamma link, not downloaded, sidestep the whole problem. But anyone who has already committed to delivering a .pptx file to a client, a boss or a conference organizer should generate a real deck and test the export before relying on Gamma for that specific job, not after.
What users say in reviews
Gamma’s review scores split more sharply by platform than any other tool checked for this guide. 
G2 puts it around 3.9 to 4.1 out of 5, but from a thin sample, 27 to 39 reviews depending on which search pass you trust, so treat that number as directionally useful rather than statistically solid. 
Capterra’s 3.8 out of 5 rests on just 4 reviews, too small a sample to be meaningful on its own.
Trustpilot is where the real risk shows up. A direct fetch of Gamma’s Trustpilot page for this review confirmed 1.6 out of 5 from 129 reviews, 75% of them one-star, the worst score of any tool in this guide. The dominant complaint theme is billing: unexpected or automatic renewal charges, and refund requests met with automated replies inside the standard 7-day window rather than a human response. A second, separate theme covers AI quality directly, with reviewers describing the assistant as ignoring specific edit instructions while reporting that it made the requested change.
Who should skip it
Skip Gamma if a working .pptx handoff is non-negotiable; test the export on a real deck first, or compare Canva, whose PPTX export doesn’t carry the same native-format conversion problem. Skip it too if Gamma’s Trustpilot score gives you pause about the billing relationship, in which case Beautiful.ai’s template-driven approach trades away prompt-to-deck speed for a more conventional subscription. For a non-linear visual format instead of either slides or cards, see the Prezi review.

Pricing note: Gamma's free plan is permanent and needs no credit card: 400 AI credits at signup that don't refill, up to 10 slides per generation, a 'Made with Gamma' watermark on every export, and the standard AI model only. Plus runs $12/seat per month billed monthly or $9/seat per month billed annually ($108/yr). Plus removes the watermark, raises the prompt limit to 100 slides, unlocks the advanced AI model, and gives 1,500 credits a month. Pro runs $25/seat per month monthly or $18 annually ($216/yr), with 4,000 credits, unlimited slides per prompt, up to 10 custom domains, the premium AI model, and a team workspace with a shared brand kit. Ultra runs $100/seat per month monthly or $90 annually ($1,080/yr), with 20,000 credits, up to 100 custom domains, and the most advanced AI model Gamma offers. Annual billing saves 25% to 28% depending on the plan. Credits are consumed per action, and the cost per action varies by AI model and complexity, so one credit doesn't map to one slide at a fixed rate.

Frequently asked questions
Is Gamma free to use?
Yes, permanently, not just as a trial. Free gives you 400 AI credits at signup that don't refill, up to 10 slides per generation, and the standard AI model, with a 'Made with Gamma' watermark on every export and no credit card required to start.
How much does Gamma cost?
Billed monthly, Plus runs $12 per seat, Pro $25 and Ultra $100. Billed annually, Plus is $9 a month ($108 a year), Pro $18 ($216) and Ultra $90 ($1,080), so a year upfront saves roughly 25% to 28%. Higher tiers add more AI credits and fewer export restrictions. Source: vendor pricing page, checked in browser 2026-11-08.
Does Gamma export cleanly to PowerPoint?
Not always. Gamma's native format is a scrollable card canvas, not a fixed slide grid, and converting that to PPTX is the single most-repeated technical complaint in its reviews: layouts can break, animations and embeds flatten, and images resize unpredictably. PDF, PNG and Google Slides exports are also available, and the watermark disappears once you're on a paid plan, but anyone who must hand off a working .pptx file should test the export on a real deck before relying on it.
Why is Gamma's Trustpilot score so much lower than its G2 score?
The two platforms measure different things from different audiences. Gamma's G2 score sits around 3.9 to 4.1 out of 5, but from a thin sample, 27 to 39 reviews, likely power users who sought out G2 specifically to leave feedback. Trustpilot's 1.6 out of 5 comes from 129 directly confirmed reviews, 75% of them one-star, and the dominant complaint there is billing and refund handling, not the product itself. Report both rather than averaging them or quoting only the flattering one.
What makes Gamma different from Canva or Prezi?
Gamma's deck isn't built from fixed slides by default; it's a scrollable card-based canvas that can also publish as a live interactive web page. That's a real differentiator from Canva's and Prezi's slide-based (or, for Prezi, zoom-canvas) formats, but it's also the root cause of the PPTX export friction covered above.
Bottom line
Gamma is the most AI-native tool in this guide: feed it a prompt or a document and it builds the whole deck, with real-time multiplayer editing and a permanent, no-card free plan on top. That's a genuine strength, and it's also where two specific risks sit that any buyer needs to weigh before signing up. Its Trustpilot score, 1.6 out of 5 from 129 directly confirmed reviews, is the worst of any tool checked for this guide, driven almost entirely by billing and refund complaints rather than product-quality gripes. And its native scrollable-card format doesn't convert cleanly to PowerPoint's fixed slide grid, a recurring, well-documented complaint for anyone who needs to deliver a .pptx file rather than share a live Gamma link. If your audience is fine viewing the deck as a web link and you've read the billing terms closely, Gamma's speed is real. If a clean PowerPoint handoff is non-negotiable, test the export before you commit.
