Gamma vs SlideSpeak (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 SlideSpeak if

• Fits if you start from a long PDF or Word file and want slides from it
• Works for teams that want an API to generate decks

Look elsewhere if

• Tight if you stay free: 100 credits once, about 3 presentations
• Pricey if you want exports, as PDF and PPT start at Premium, $29 a month
• Skip it if you want your own template cheaply, as the add-on is $129 on every paid tier
• Watch out: prices show a discount from a crossed-out figure with no end date
• Watch out: Lifetime Premium Plus for $359 is advertised as a limited offer

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.

• 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.

SlideSpeak

• The free plan's 100 credits are a sign-up grant, enough for about 3 presentations.
• A custom template add-on costs $129 on every paid tier.
• The page shows an annual option with 15% off, but its price was not displayed in the page text.
• Pricing is shown as a discount from crossed-out figures with no end date; recorded here as the charged price.
