Kinsy vs Gamma: Which AI Presentation Maker Should You Use?

By the Kinsy team · Published 10 July 2026

Gamma is the tool that made "AI deck maker" a category, and it remains the name most people try first. We build Kinsy, its direct competitor, so we'll be precise about where Gamma is genuinely better — and exact about the one architectural choice that decides this comparison for most professional users.

The short version

What Gamma gets right

Credit first. Gamma's generation is fast and its web output is polished. The card format — slides that flow and scroll like a modern webpage — is genuinely pleasant to consume on a laptop or phone, and analytics on shared links are useful for sales teams. The product is mature, the free tier is generous, and paid plans (a Plus tier around $10/month at the time of writing, using a credit system much like ours) are fairly priced.

If the deliverable is a URL, we'd struggle to tell you Kinsy is obviously better. That's not where we aimed.

The card problem

Gamma's defining choice is that a "slide" is a web card: variable height, reflowing, responsive. That choice makes the web experience great and the PowerPoint experience structurally hard, because PPTX slides are fixed-geometry canvases. Converting one into the other means making lossy decisions — where to cut a flowing card, how to freeze responsive spacing, what to do with web-only elements. In our testing, exports commonly arrive with shifted spacing, rasterised elements you can no longer edit as text, and layouts that read "converted" rather than "designed".

None of this is a bug in Gamma. It's the honest cost of being web-first. But it means the moment your workflow includes PowerPoint — and for most consultants, founders, bankers, academics and students it eventually does — you're maintaining two versions of the truth: the pretty one in the browser and the approximate one in the file.

How Kinsy approaches the same problem

Kinsy made the opposite bet: the .pptx you download is the deliverable, and everything else in the product exists to serve it. Open a Kinsy export in PowerPoint and every headline, bullet and label is an editable object, positioned exactly where the preview showed it, in the typeface it was designed in — on any machine, with no missing-font fallbacks. Keeping that true on every single deck is the hardest thing we've built.

We wrote a full technical explainer on this: why AI deck tools break on export, and how Kinsy doesn't.

Intelligence: filler vs argument

The second real difference is what the AI is asked to do. Both tools turn a prompt into slides. Kinsy additionally:

• Plans the narrative before designing — a storyline with a claim, support and a close, not eight cards of adjacent content.
• Researches live with citations when the topic is time-sensitive, filtering for recent sources and grounding every claim in a numbered source list.
• Runs a fact-check pass that extracts every checkable claim in the draft and rewrites anything the sources don't support — before you ever see the deck.
• Writes real speaker notes for every slide: bridges, emphasis, and what to say when someone asks about slide four.

Gamma has web-lookup features, but in our testing it doesn't enforce grounding — fluent, wrong sentences survive to the final deck, which is precisely the failure mode that embarrasses you in a meeting. On evergreen topics both tools do fine; on anything recent or factual, verification is the difference between a draft you check and a draft you present.

Editing and iteration

Both products let you refine with natural language, and both do it well. Kinsy's edits are metered per action (a slide edit costs 5 credits, a deck-wide pass 2 per slide), keeps full version history with one-click restore, and — because output is native PPTX — always leaves you the escape hatch professionals actually use: open the file and nudge it yourself in PowerPoint. With Gamma, hand-finishing means either working in their editor or accepting the exported approximation as your new baseline.

Pricing

Pricing as of July 2026, as published by each vendor — check current pages before buying. We build Kinsy, so verify every row yourself.

Gamma is cheaper at the entry point; Kinsy's grant is larger and each credit buys a heavier pipeline (research, verification, notes, native rendering). If price is the deciding factor and export isn't, Gamma wins this row.

Head to head

The highlighted column is our claim about our own product — we build Kinsy, so verify every row yourself; both free tiers make that a twenty-minute job. Pricing above as of July 2026.

The bottom line

Gamma is an excellent web-publishing tool that can approximate a PowerPoint. Kinsy is a deck author that produces the PowerPoint. Decide where your deck will actually be presented, and the choice makes itself. And as always: run your own brief through both, export both, and open the two files side by side — the comparison takes twenty minutes and settles the question better than we can.
