Gamma Review 2026: I Recommended It Without Qualification. I'm Canceling.

Rewritten September 3, 2026. The original version of this review recommended Gamma without qualification. That recommendation no longer stands, and I have left the reasoning intact below so you can see exactly what changed and judge it yourself.

I upgraded to Gamma’s paid tier and wrote in July that it had become my go-to presentation tool, hands down. I meant it. My first LinkedIn carousel in Gamma took about ten minutes, after a frustrating struggle building one in PowerPoint the week before, and that reclaimed time went straight into posting more often.

I cancel at renewal. Gamma changed its create flow, and the thing I paid for stopped working the way it worked when I paid for it.

What Changed

Gamma’s create flow now routes to generation by default. You describe what you want, and Gamma writes the content.

That path exists to produce copy from a brief, and it does that well. The problem arrives when you already have the copy.

I supply finished text. My LinkedIn posts get written, edited, and reviewed before any deck exists, and the carousel is a rendering of that text rather than a first draft of it. I also supply a prompt setting format rules: aspect ratio, card count, word ceilings per card, order preservation, and a fixed call to action.

Gamma now rewrites the content and disregards the rules. Not occasionally. As the documented behavior of the path it puts in front of you.

That is a regression back to the exact problem that made me leave PowerPoint. I did not switch tools because PowerPoint could not write my slides. I switched because assembling slides by hand ate time I would rather spend writing. A tool that rewrites my words and ignores my formatting instructions returns me to manual assembly, which is where I started.

The Workaround, and What It Costs

I looked for one. The AI generation path disregarded the prompt, changing formatting, font, and slide count regardless of what the instructions specified. Gamma also offers a Paste in text option with a Preserve mode meant to retain your wording, but the careful workflow through that path takes far longer.

A workaround that slow cancels the reason I bought the tool. It returns me to the manual effort I left PowerPoint to escape, through a tool I pay for specifically so I would not have to spend that time.

That path runs about thirty minutes against the thirty seconds the old flow took. The product sells on speed, and the interface offers no route back to it.

Worth knowing before you rely on Preserve at all: Gamma’s own documentation describes it as retaining your text “sometimes structuring it where it makes sense to do so,” which is not a guarantee.

The Fix Is Real, and It Is Behind a Paywall

Gamma’s API exposes exactly what the interface took away. A textMode parameter accepts preserve explicitly. You set it programmatically, so nothing silently resets it between sessions. Format, dimensions, image sourcing, and additional instructions all pass as parameters. It scripts, which means the thirty minutes collapses to one command.

API access requires the Pro tier.

So the sequence for a paying subscriber runs: the workflow you bought degrades, the interface workaround stretches thirty seconds into thirty minutes, and the clean fix costs more money.

That is the part I cannot get past. Charging for the repair of a regression is a decision somebody made.

What I Tested, and What I Did Not

The rewriting described above comes from working with the product rather than from reading about it. The AI generation path rewrote content I supplied and overrode formatting, font, and slide-count instructions given in the prompt.

What I did not test is the API, because API access requires the Pro tier and I declined to pay more to repair a workflow that already worked. The textMode: preserve parameter appears in Gamma’s documentation and may well behave exactly as described.

That gap does not soften the finding. A fix that costs an upgrade is not a fix for the subscriber whose tool regressed.

What Gamma Still Does Well

Generating a deck from a brief remains genuinely good. Describe a narrative in a paragraph and Gamma produces a coherent structure with sensible layout and typography in under a minute. The output tells a story rather than dumping bullets onto slides, and the default themes avoid the AI-made-this look that afflicts most competitors.

If you want a tool to write your presentation, Gamma writes a good one. That use case is intact and I would still recommend it for exactly that.

The failure is narrower and, for me, disqualifying: Gamma became a poor tool for rendering content you already wrote.

What I Replaced It With

An HTML template and a twenty-line script.

Cards are plain text separated by a divider. A script reads them, applies a stylesheet carrying my palette and typography, and renders a 1080x1350 PDF through headless Chromium. One command. No model in the loop, so nothing rewrites anything, and the output is byte-identical across runs.

It took an afternoon to build and it produces exactly what I ask for every time.

That is the uncomfortable comparison. A subscription product lost to a stylesheet and a script, not because the script is clever but because it does the one thing I needed and does not argue.

Anyone who wants design variety, image generation, or genuine layout intelligence still has a real reason to pay for a tool. Anyone who supplies finished text and wants it rendered faithfully should look hard at whether they need one at all.

Who Should Still Use Gamma

Use it if you want AI to draft your content, you value speed to a first draft over control of the words, and you work in a format where Gamma’s defaults suit you.

Look elsewhere if you arrive with finished copy, you enforce formatting or brand rules that must hold, or you produce the same artifact repeatedly and need it to come out the same way each time.

Alternatives worth a look: Beautiful.ai for structured, brand-consistent decks. Canva if you are already inside its ecosystem. And for repeatable, rule-bound output, an HTML template you control, which costs nothing per document and never changes underneath you.

Pricing

Plus runs $10/month, the tier I paid for. Gamma’s developer documentation lists API key access on the Pro, Ultra, Teams, and Business plans. Check Gamma’s pricing page for current rates on those tiers.

The Bottom Line

In July I wrote that tools earn the go-to label when they change my workflow, and that Gamma had changed mine. That was true when I wrote it.

Gamma changed my workflow a second time, in the other direction. The default path now rewrites what I give it, the fix through the interface turns thirty seconds into thirty minutes, and the clean fix costs more money.

I cancel at renewal. My recommendation comes down with it. I would rather publish that than leave a July endorsement standing over a September product.

A tool that stops respecting your input has stopped being a tool and started being a collaborator you did not ask for.
