Gamma review: an AI presentation tool that takes you from outline to a solid proposal draft

Gamma is an AI service for creating presentations, documents and web pages. You start from one of three points: a short prompt ("sales proposal for marketing a mid-market residential complex, 12 slides"), pasted text (notes, an outline, a chunk of strategy) or an imported file – an existing presentation or document the service will reformat. Gamma then proposes a section-by-section plan, you edit it, pick a visual theme – and get a formatted draft with text and images.

The key difference from PowerPoint is the "card" format instead of fixed-size slides. A card stretches to fit its content: add a paragraph or a chart and the layout rebuilds itself, nothing shifts out of place. For drafts and working materials this removes the main pain of manual formatting. Editing works on two layers: you can change text and blocks by hand, Notion-style, or ask the AI – "shorten this section", "turn this list into a table", "pick a different image".

In late 2025 the service shipped a major update, Gamma 3.0. The headline feature is Gamma Agent: a conversational mode where you edit the whole presentation with requests like "make the tone more formal and add a slide with project milestones". The agent can search the web for supporting facts and pull them into slides – convenient, but it needs checking: the facts in your proposal are still your responsibility. The update also added an API for generating presentations from your own systems and integrations – available on Pro and above.

Export: PPTX, PDF, PNG and Google Slides – you can hand a file to a client who lives in PowerPoint. Or skip exporting entirely and publish the material as a web page, then send a link: on paid plans you get view analytics – who opened the proposal and how far they read.

Gamma pays off most where presentations are a recurring process, not a one-off event. The typical workflows that fit the service best:

• Sales proposals. Keep your proposal structure as a text template (client's problem → approach → scope → timeline → price), drop in the specifics of a given client – Gamma assembles a formatted version. The path from brief to send shrinks from half a day to an hour, proofreading included.
• Client reports. You prepare the analytics numbers and conclusions yourself; Gamma turns them into a clean, consistently styled document. The agency's monthly routine stops eating an account manager's evening.
• Media plan or budget defense. A spreadsheet plus an explanatory note becomes a meeting-ready deck – the "goals → channels → budget → forecast → risks" structure generates from pasted text with almost no layout fixes.
• Project deck. For a new residential complex or product – a draft for internal alignment between sales and contractors in a single pass. Not a showcase piece, but a working document that otherwise would never get made at all.
• Placeholder landing page. The web page format covers "we need a page for this hypothesis by tomorrow" – no front-end developer, no CMS.

At Matveo we file Gamma under the layer of narrow tools that get plugged into a specific process – in this case, the pipeline of client-facing materials. I wrote about the base setup this kind of pipeline grows out of in my article on AI tools for marketers: first one strong LLM plus processes, then specialized services.

Personalization is a scenario of its own. If you have three audience segments, one master proposal structure easily becomes three versions with different emphasis: yield for the investor, infrastructure for the family, partnership terms for the agent. It is the same logic as in AI-driven microtargeting, applied to sales materials instead of ads.

Gamma's internal currency is credits: they are spent on card generation, images, Agent requests and API calls. Spend scales with volume – a long presentation with lots of images costs more than a short text-only one. Plans as of publication (August 2026):

The price ranges are there because the final number depends on how you pay: annual billing is noticeably cheaper than monthly. Unused credits roll over, but not indefinitely – up to twice your plan's monthly allowance. On the free plan the 400 starting credits do not refill: they cover a few presentations, after which you either invite colleagues through the referral program (200 credits per person) or pay.

First and foremost – the generic AI design shows. Gamma produces clean but recognizable output: similar grids, characteristic gradients, the stock feel of generated illustrations. A trained eye spots such a presentation in seconds. For a working proposal or a report that is fine. For an investor pitch, a tender presentation or a board meeting it is not: there the material has to look custom-made, and you cannot get around a designer. Gamma's honest role in those projects is a fast structural draft that a designer then rebuilds.

Second – the substance comes from a human. The service will beautifully format whatever you feed it, weak offers and made-up numbers included. What makes a proposal convincing is benefits, proof and calculations – Gamma will not invent those, and the Agent's web search means checking every fact before it goes to a client. Garbage in – beautifully formatted garbage out.

• PPTX export is imperfect. Flexible card layouts sometimes need manual touch-up after conversion to the rigid slide format – check the file before sending, especially tables and non-standard blocks.
• Complex data is not a strength. Charts and tables come out basic; serious analytics visualization is still easier to build in specialized tools and paste in as an image.
• The credit economy takes getting used to. An iterative style of working – "regenerate this ten more times" – burns credits faster than you expect. It is cheaper to finalize the outline and text first, then generate.
• Your data goes to the cloud. If a proposal contains sensitive commercial information, clear the use of an external service with your company's policy and the client's.

A quick look at the neighbors – one line each, with no claim to a full review of any of them:

• PowerPoint + Copilot – the logical choice if your company lives in Microsoft 365 and corporate templates: weaker generation, but the format and approval flows are native.
• Pitch – built for team collaboration on presentations and startup pitches; stronger at co-editing, weaker at generating from scratch.
• Beautiful.ai – smart templates that will not let you break the layout; good for consistency across a team, but less flexible in formats – documents and web pages are not its territory.

My verdict: Gamma is worth adopting for a regular flow of routine materials – proposals, reports, budget defenses, internal decks. There it genuinely gives you back hours every week. Start with the free 400 credits on a real task – rebuild the last proposal you sent, for instance, and compare it with the original on time and quality. If the difference is tangible, a paid plan pays for itself quickly. And leave the "impress them with design" jobs to a designer – this is not that tool, and the service does not pretend otherwise.
