| 3.6GPAGammaExcellent | 2.6GPAPlus AIGood | |
|---|---|---|
| Value for money | BOur listing can't state what Plus, Pro or Ultra cost, because Gamma shows those only on its pricing page. The one figure on record is Business at $40 a member a month, billed annually. Annual billing is 28% off, and Ultra is monthly only. | BBasic is $10 a user a month billed annually, or $15 monthly. That's right in the middle for this category, and it covers both add-ons with 1,500 AI credits a month. Turning an uploaded document into slides needs Pro at $20, mind. |
| Free plan and trial | BFree with no time limit and no card. But it's 400 AI credits that don't refresh, 10 slides a prompt and basic image models, and PDF and PowerPoint exports carry a Gamma badge. Each referral earns 200 more credits. | DNo free plan. You get a 7-day trial of any paid plan with 1,000 AI credits, but you have to hand over a credit card to start it. |
| Features | AStart from a topic, pasted text or an imported PowerPoint, Word or PDF file. The agent researches, writes, designs and adds images. Present in the browser with speaker notes, export to PDF, PNG or PowerPoint, or publish the thing as a website. | BWhole decks from a prompt, single slides in a layout you pick, Rewrite and Remix for slides you already have, plus an API, Zapier and an MCP server. It's an add-on, though, not an editor, and the AI editing tools don't work in its own web app. |
| Ease of use | A4.8 from about 1,100 App Store ratings. You describe what you want and approve a plan, then ask for changes in plain words. No slide-arranging needed. | BNo App Store rating on record, so B is as high as we go. You add it to Google Slides or PowerPoint and work where you already do. Watching your credits is the fiddly bit, as a typical task uses 40 to 170. |
| Platforms and integrations | AWeb, iPhone and Android, with ChatGPT, Claude and Slack connectors on every plan and a REST API from Pro up. The phone apps are early access, though: US and Canada only, and they edit through the agent alone. | BIt lives in Google Slides and in PowerPoint for Windows and Mac, with a web app that makes decks to export. There's an API, Zapier and an MCP server. No phone apps, and PowerPoint for iPad isn't supported. |
| Best for | a first-draft deck from a prompt or a file | AI slides inside Google Slides and PowerPoint |

Who each one suits
Gamma
- Turning a topic, notes or an existing file into a first-draft deck
- People who would rather describe changes than arrange slides by hand
- Teams automating deck creation through the API, Zapier, Make or n8n
Plus AI
- People who want AI help without leaving Google Slides or PowerPoint
- Consultants and sales teams turning documents into editable native slides
- Teams that need generated slides to follow their logo, colors and fonts
Worth knowing
Gamma
- Plus, Pro and Ultra prices are shown only on Gamma's pricing page; its help center gives the Business price, $40 per member per month billed annually.
- Free-plan AI credits do not refresh: accounts start with 400 and earn 200 more per referral. Paid plans get monthly credits, from 1,000 on Plus to 20,000 on Ultra.
- API keys, detailed viewer analytics, password protection and custom domains start at the Pro plan, and Ultra is sold on monthly billing only.
- The mobile apps are in early access, limited to the US and Canada, and edit only through the agent, with no manual editing.
Plus AI
- There is no free plan: a paid plan is required after the 7-day trial, and starting the trial needs a credit card.
- It is an add-on, not a standalone editor: it runs inside Google Slides and PowerPoint for Windows and Mac, and PowerPoint for iPad is not supported.
- Its own web app only generates decks for export as .pptx; the AI editing tools work in the add-ons, not in the web app.
- AI credits belong to each user and reset monthly. Document uploads and image generation need Pro, and custom branding needs Team.
Key features
Gamma
- Generate, paste or import
- Three ways to start: generate a draft from a topic, paste existing text for Gamma to lay out, or import a PowerPoint, Word or PDF file or a URL to be restyled.
- Agent
- The agent asks about goal and audience, shows a plan to approve, then researches, writes, designs and adds images. Changes are requested in plain language in the same chat.
- Present mode
- Decks are presented full screen or in a tab, with a presenter view for private speaker notes, a spotlight mode that highlights the current block, and a follow link viewers can use to keep pace.
- Export and import
- Exports to PDF, PNG and PowerPoint, with tables kept editable in PPTX. Imports accept PowerPoint and Word files up to 200 MB and PDFs up to 100 MB.
- Sites and custom domains
- A gamma can be published as a website. Pro can publish up to 10 multi-page sites to custom domains, and Ultra and Business up to 100.
- API and connectors
- A REST API, generally available since November 2025, creates gammas from text or templates on Pro and higher plans. ChatGPT, Claude and Slack connectors work on every plan.
Plus AI
- Generate from a prompt or a file
- A few sentences, a preset, or an uploaded PDF, Word, PowerPoint or text file becomes a full deck created directly in Google Slides or PowerPoint. File uploads need the Pro plan.
- Insert, Rewrite and Remix
- Insert adds a single slide in a chosen layout, Rewrite summarizes, expands or changes tone, and Remix reformats existing content into a different slide design.
- AI credits
- Using the AI agent draws on a monthly credit limit per user, from 1,500 on Basic to 6,000 on Team. A typical task uses 40 to 170 credits, and limits reset on the billing date.
- Custom branding and templates
- The Team plan applies a logo, colors and fonts to Plus AI templates. Enterprise customers can have slides generated from their own slide masters and asset libraries.
- Presets and custom instructions
- Frequently used prompts are saved as presets, and custom instructions store context about a person or company for later generations. Team plans share a preset library.
- API, Zapier and MCP server
- The Presentations API creates native PowerPoint files over HTTP with a bearer key and needs a Pro or Team plan. Zapier and an MCP server offer the same without code.
