Gamma vs SlidesAI (2026): which should you pick?

Pick Gamma if

• Fits if you have notes or an old file and want a first-draft deck out of them
• Works for asking "make slide 4 shorter" rather than dragging boxes around

Look elsewhere if

• Tight if you're never paying, because the 400 free credits don't come back
• Skip it if you want clean exports for free, as PDF and PowerPoint files carry a Gamma badge
• Not for you if you edit on your phone outside the US and Canada, where the apps aren't offered yet
• Watch out: Plus, Pro and Ultra prices aren't on record, and Business is $40 a member a month billed annually
• Pricey if you need the API, viewer analytics, passwords or custom domains, as all start at Pro

Pick SlidesAI if

• Fits if you make slides in Google Slides and want a draft from your notes
• Works for students on the $10 Pro plan

Look elsewhere if

• Tight if you stay free: 200 credits a month, which is about one deck
• Skip it if you want unused credits to carry over, as they do not and free users cannot buy more
• Pricey if you want 20 or more slides a deck, as that needs Pro, and 50+ needs Premium at $20.83
• Watch out: Teams Pro and Teams Premium prices were not read, and the monthly prices are not in the page text

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.

SlidesAI

• Unused credits do not roll over, and extra credits cannot be bought on the free plan.
• A Monthly Billing option exists, but its prices are not in the page text, so only yearly prices are recorded.
• Teams Pro and Teams Premium add roles and central billing; their prices were not read.
• Individual and Team plans are sold by Dodo Payments as merchant of record.

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.

SlidesAI

Create from a topic or document

Type a topic, paste notes or a script, or upload PDF and Word files (Pro and up). It asks a few questions about slide count and tone first.

Brand kits

Import your branded PPTX template and decks follow its layouts, colors, fonts and logo: 1 kit on Basic, 3 on Pro, 6 on Premium.

AI credits and model tiers

Credits pay for AI work. A 10-slide deck on the default model uses 105 credits; higher-quality models cost more per action.

Outline before slides

An outline opens beside the chat with one line per slide, which you can edit or reorder before the text is written.

Works inside other tools

Available as a Google Slides add-on, a PowerPoint add-in and in ChatGPT, as well as the web app.

Export

Present, share a link, or export to PowerPoint or Google Slides.
