Gamma's free plan gives 400 AI credits once at signup with no monthly refill, and its credit system punishes image-heavy decks. Paid plans run from Plus ($9/mo) to Ultra ($90/mo), and since October 2026 the individual plans no longer have an annual discount.
Canva is the better pick when slides are one of many design jobs. Genspark also turns one prompt into slides, with free credits that refresh daily. If you already work in Office, Copilot via M365 Premium ($19.99/mo) builds decks in PowerPoint.

|---|---|---|---|---|
| Gamma | Yes | $9/mo | $90/mo | Fast first-draft presentations and one-page sites without opening a design tool |

Monthly prices in US dollars before tax, from each vendor's official pricing (US list price; weekly-billed plans converted to a monthly figure). Updated November 2, 2026
Canva covers presentations alongside 1,000+ other design types on its free plan. Pro ($18/mo) unlocks the full Magic Studio suite, Magic Resize and premium templates.
Pick it if: you also make social posts and marketing assets and want them on-brand with your slides.
Where it falls short: AI credits run out fast even on paid plans, and output stays template-bound.
Full Canva pricing →Genspark routes across 70+ models to turn one prompt into slides, docs or video. Free refreshes about 100 credits a day, and Plus ($24.99/mo) gives 10,000 credits a month with commercial use.
Pick it if: you make decks regularly and Gamma's one-time free credits ran out.
Where it falls short: Video and voice tasks drain credits fast, and free chat and image use is only a promotion through June 2027.
Full Genspark pricing →M365 Premium ($19.99/mo) includes the full Office apps and advanced Copilot chat, and PowerPoint decks are one of Copilot's core jobs.
Pick it if: your decks have to end up as PowerPoint files anyway.
Where it falls short: On the family plan, Copilot AI is for the owner only, and agentic AI usage is limited.
Full Copilot pricing →Manus is an autonomous agent that plans, browses and delivers multi-step tasks, including slides and docs. Free gives 300 daily credits; Pro ($20/mo) adds 4,000 credits a month.
Pick it if: you want the agent to research the topic and then build the deck.
Where it falls short: Credits burn fast on complex tasks, and ownership is clouded after Chinese regulators ordered Meta's acquisition unwound.
Full Manus pricing →Gamma, Genspark and Manus all spend credits per generation, and images are the expensive part. Run the same outline through two free tiers and note how much of the allowance a single image-heavy deck uses. That figure, multiplied by the decks you make each month, tells you which plan you actually need.
Genspark Free refreshes about 100 credits every day and Manus Free 300, while Gamma's 400 free credits are one-time. Canva Free covers presentations alongside 1,000+ other design types.
Gamma is faster at turning a prompt into a full deck. Canva is better if you want to design slides from templates by hand and also make social posts and marketing assets.
How we choose: prices come from each vendor's official pricing page and are re-checked every week. We take no affiliate fees, so rankings aren't for sale.
