Best free AI presentation makers, compared on the fine print
“Free” means different things: some tools need an account, some keep PPTX export for paid plans, some add a logo. We read each tool's own pricing page and put the limits side by side.
Main page: Slidebrew AI PPT maker
In shortThe best free AI presentation maker depends on which limit matters to you. Needing no account and a free editable PPTX: Slidebrew (3 AI decks a day, no watermark), FreeSlide (free .pptx, no sign-up, rate-limited per hour) and SlideGen (free and unlimited with ads, no sign-up) all qualify. MakeDecks gives 3 free decks a week with PPTX after you sign in. Wonderslide's free plan exports PDF only, SlidesAI's free plan gives 200 credits a month for decks up to 10 slides, and Gamma's free credits are one-time (reported). When you outgrow the free tier, Slidebrew sells pay-once packs ($4.90 for 20 decks) instead of a subscription. We make Slidebrew, so every figure below links to the vendor's own page (checked 2026-11-09).
