Gamma review

What it is

Gamma generates presentations, documents and simple websites from a prompt or a pasted document. Instead of slides with fixed dimensions it uses cards that expand to fit content, which removes the most tedious part of deck building.

Where it shines

Speed to a presentable draft. Paste a three-page strategy memo, choose a theme, and ninety seconds later you have a fifteen-card deck with sensible section breaks, reasonable hierarchy and images. For internal updates, workshop material and sales decks, that draft is often ninety percent of the job.

The card model is genuinely clever. Content never overflows, spacing never breaks, and reordering sections does not destroy the layout — the failure modes that make PowerPoint editing miserable simply do not occur.

Editing after generation is also good: nested cards, embedded video, live charts and tables behave like a modern web document rather than a slide.

Where it falls short

Everything looks like Gamma. The default themes are attractive and instantly recognisable, and in a market where every startup is using the same tool, that similarity works against you in a pitch.

Control has a ceiling. If you need a specific element at a specific position in brand colours with exact typography, you will fight the tool, and eventually export to PowerPoint and finish there. Heavily branded corporate templates do not import.

Pricing in plain English

Free with 400 starting credits and Gamma branding on exports. $10 a month for Plus, which removes branding and unlocks unlimited AI generation. $20 for Pro with advanced models, analytics and custom domains.

Who should use it

Founders, consultants, marketers and managers who make decks regularly and are not designers. Anyone whose deck must look bespoke should treat it as a drafting tool only.

A note on getting better output

Gamma is far better at restructuring than at inventing. Give it a written document with real content — a memo, a report, notes from a call — rather than a one-line topic, and the deck it produces will have substance instead of generic filler. Then delete a third of the cards. The generated version is always longer than the version anyone wants to sit through.
