Gamma alternatives

Gamma alternatives, judged on what you get back.

Every AI deck tool makes slides in under a minute. They differ enormously in what exists afterwards, and that is the only comparison worth making.

Before you compare anything

Why people look for something else

Generation speed is rarely the complaint. These three are.

The output is the tool's format, not yours

Gamma's cards work well as a web document and awkwardly as a deck someone else has to edit in PowerPoint. If the file has to survive being handed to a colleague, check the export before you check anything else.

Editing means re-prompting

In several of these tools, changing a layout means asking the AI again rather than dragging the thing you want to move. That is fine for a first draft and frustrating on the fourth revision, when you already know what you want.

It generates the deck but not the meeting

AI deck tools stop at the artifact. If the presentation is going to a live audience who should be doing something other than watching, none of them help with that part.

What each one hands back

Every tool here turns a prompt into a complete-looking deck, so that is not where they differ. These rows are about what exists afterwards, which is what you live with.

yesyes, and growingpartialno. “Partial” means a version of this exists rather than none. Cards you can restyle but not restructure, or a template that reflows on its own terms.

What Gamma is genuinely good at

Worth knowing before you compare, because one of these may be exactly what you need.

Its AI does not stop at slides. The same prompt box produces documents, web pages and social posts, so if you want one tool covering several output formats, that breadth is the reason to pick it. Decka is narrower on purpose and only makes presentations.
Prompt to complete deck, quickly and coherently. The first draft is usable rather than a scaffold.
Publishing to the web is a first-class path rather than an export afterthought, and a Gamma link reads well for someone who was never in the room.
Consistent visual output without design work. The themes hold together across a whole deck without intervention.

The shortlist, and what each one hands you

The Gamma competitors below are grouped by what exists when the AI has finished. A deck in a tool's own format, a real presentation file, or something you present live.

Decka

that's us

A generated deck you can actually redesign, then present live

What it does well: One prompt produces a complete presentation into a freeform editor, where every slide is real editable objects on a canvas rather than a card the tool owns. Move one element without regenerating the slide around it. Restyle a single object when the theme should not apply. Collaborate on it in real time. The same deck then runs 16 kinds of live audience activity from its own slides, and the PowerPoint add-in and Google Slides extension bring them into a deck you already keep in those tools: 15 of them inside PowerPoint and Google Slides, with Bingo in Decka's own editor.
The trade-off: It is the newest tool here, so the template library is smaller than Canva's. Decka also only makes presentations, so if you want one prompt box that writes documents and web pages too, this is the narrower choice. The live-audience half earns you nothing if the deck is only ever a document you send.
How it is priced: Free to build in. The free tier caps audience size per live session, and paid plans are per presenter.

See the AI presentation maker

Beautiful.ai

Slides that fix their own layout as you edit

What it does well: Smart templates reflow automatically when content changes, so a deck stays visually consistent without anyone nudging boxes. Strong for teams where not everyone is a designer.
The trade-off: That automation is also the constraint. When you want a layout the template does not want to make, the tool works against you.
How it is priced: Paid per user, with a free trial rather than a free tier.

Canva

When the deck is one of six things you need

What it does well: An enormous asset and template library, and the same file becomes a social post, a poster and a document. AI generation is built in, and most organisations already have it.
The trade-off: It is a general design tool. Presentation-specific work such as speaker notes, complex builds and a serious PowerPoint round-trip is not where its strength lies.
How it is priced: Free tier with a large template library. Paid per user for brand and premium assets.

Chronicle

Decks that have to survive a serious audience

What it does well: Turns raw notes, an outline or an existing deck into slides aimed squarely at business use, from sales to leadership to consulting, rather than at looking good in a demo.
The trade-off: Narrower than the general-purpose tools by design, and the free route is a trial rather than a standing free tier.
How it is priced: Free trial, paid plans, and an enterprise tier.

Pitch

Sales decks a team maintains together

What it does well: Built around collaboration and brand consistency across many decks, with templates, shared components, and analytics on how a sent deck was read.
The trade-off: AI generation is a feature rather than the product. If you want prompt-to-deck as the main event, Gamma is ahead.
How it is priced: Free tier, with paid plans per user for team features.

Presentations.ai

Corporate decks that must obey a template

What it does well: Oriented around brand and template compliance, which is the actual requirement in large organisations where decks get reviewed before they are sent.
The trade-off: Less creative range, and the compliance orientation is overhead if nobody is going to review your deck.
How it is priced: Free tier, with paid plans per user.

Plus AI

Keeping everything in Google Slides or PowerPoint

What it does well: Runs as an add-on inside the tools you already use, so the AI writes into a native file. Nothing to export, and no new format for a colleague to learn.
The trade-off: Bounded by what its host application can do, so the output is more conventional than a purpose-built AI tool's.
How it is priced: Paid per user, with a free trial.

Microsoft Copilot in PowerPoint

When the deliverable is a .pptx from the first minute

What it does well: Generates directly into PowerPoint with access to your organisation's own documents, and adds no vendor to the security review.
The trade-off: Requires the right Microsoft licence, and the design output is plainer than the specialist tools'.
How it is priced: An add-on to an existing Microsoft 365 licence.

Google Slides with Gemini

Organisations that live in Workspace

What it does well: Generation and image creation inside the editor everyone already has, with sharing and permissions that need no explanation.
The trade-off: The weakest generation of the group, and it inherits Google Slides' limits on typography and layout.
How it is priced: Included with the relevant Google Workspace plan.

Prezi

Talks that are not a sequence of rectangles

What it does well: Zooming, non-linear movement across one canvas, which suits a talk with a spatial structure and is memorable when it fits.
The trade-off: When it does not fit it is a distraction, and it is the least conventional artifact here to hand to someone else.
How it is priced: Free tier with public projects. Paid per user.

Every entry above carries a trade-off, including ours. Prices are described by their model rather than by a figure, because a number copied from a competitor's pricing page goes stale without warning and a stale number is worse than none.

The case for Decka, stated plainly

The AI deck tools stop at the artifact. Decka generates the deck and then the deck does something, because underneath the generator is a full presentation editor with an audience layer built into it.

Presentations, and nothing else

Gamma's prompt box also writes documents and web pages, and that breadth is a real reason to choose it. Decka does one thing. Everything in the editor is there because a presentation needed it, which is why the generated deck opens as a designable canvas rather than a format borrowed from a document tool.

Generation you are not locked into

Cards and smart templates hold their shape by design, which is what makes them fast and what fights you on revision four. Decka generates onto a freeform canvas, so the slides come back as real objects and the second draft is just dragging the thing you want to move.

A real editor, free to build in, collaborative

Layers, frames, charts, media, themes, 3D tilt and presenter notes, with two people able to work in the same deck at once. The editor costs nothing to use. Paid plans are about audience size rather than about being allowed to make a presentation.

And then it holds a room

16 kinds of live audience activity run from the same slides, and the full list is below. None of the other tools on this page do any of it, and several of these activities have no equivalent in the audience-response tools either.

All 16 activity types, in full

Not a highlights reel. This is the complete list, and each one is a slide your audience joins from a phone browser with the same code. 15 of the 16 run inside PowerPoint and Google Slides; Bingo is built in Decka's own editor, because its content is bound to specific slides.

AI tools like Gamma, by what you need at the end

“Gamma alternative”, “Gamma AI alternative” and “Gamma app alternative” are one phrase covering four different requirements. The right answer changes completely between them.

A file that opens in PowerPoint

Microsoft Copilot in PowerPoint or Plus AI, both of which write into a native file rather than exporting to one. Test the export with a real deck before committing, because export fidelity is where this category most often disappoints.

Something prettier with less effort

Beautiful.ai if consistency matters most, Canva if you need the assets and the other formats too.

A free one

Decka is free to build in, and Canva and Google Slides with Gemini both attach AI to a product you may already have. Most purpose-built AI deck tools offer a time-limited trial rather than a standing free tier.

A deck that does something when you present it

This is the gap none of the AI deck tools fill, Gamma included. Decka is on this list because it generates the deck and then runs the audience participation from the same slides.

Judge these tools on the second draft, not the first

Every tool in this category can turn a sentence into a complete-looking deck, and demos are built to show exactly that. It is not where they differ, and evaluating on it tells you almost nothing.

The difference appears about twenty minutes later, on the second pass, when you know what you want to change. Ask three things of any candidate. Can I move this specific element without regenerating the slide around it? If I export to .pptx and open it in PowerPoint, does it survive? And when someone else opens this in six months to update one number, do they need an account for a tool they have never heard of?

Those three answers vary far more across this list than generation quality does, and they are what you live with for the rest of the deck's life.

FAQ

Gamma alternatives, answered

Gamma vs Beautiful.ai, what is the real difference?

Gamma generates faster and produces a card-based document that works well as a web link, and its AI also covers documents and web pages rather than only slides. Beautiful.ai is built around templates that reflow to keep a deck visually consistent as you edit it. Gamma is the better starting point. Beautiful.ai is the better maintenance tool for a deck a team keeps changing.

Is there a free Gamma alternative?

Decka's editor is free to build in, and Canva and Google Slides with Gemini both attach AI to a product you may already have. Most purpose-built AI presentation tools offer a time-limited trial rather than a standing free tier, so free in this category usually means free for the first few decks. Check which kind you are being offered before committing a deck to one.

Which AI presentation tool exports properly to PowerPoint?

Tools that write into a native file, such as Microsoft Copilot in PowerPoint or Plus AI, avoid the problem entirely because there is no conversion step. Everything else exports, with fidelity that varies by deck. Test it with one of your real presentations rather than a sample, because the failures show up in the specific things you do, like custom fonts, layered images and charts.

Can an AI-generated deck be edited freely afterwards?

This is the question most worth asking, and the answers differ more than the marketing suggests. Some tools hand back a card or block you can restyle but not restructure. Others hand back real slide objects on a canvas. Decka is in the second group, so moving one image does not require regenerating the slide.

What can generate a pitch deck and then present it live?

Generation and live presentation are usually two products. Decka does both from one deck. It generates the presentation from a prompt, and the same slides can run polls, quizzes and audience questions during the meeting, with people joining from a phone browser using a short code.
