SlidesAI vs Decktopus: Same Yearly Bill, Different Free Starts

For this page, a PPT is a PowerPoint-format (.pptx) deck. SlidesAI and Decktopus both turn a prompt or a document into slides, and on the annual option they cost almost the same amount over a year. The difference lies in the free start and in the monthly price. SlidesAI keeps a plan at US$0 with a yearly presentation cap. Decktopus’s captured pricing page shows no free plan at all, and its monthly price is more than twice its annual price. This comparison reads both pricing pages as captured on 17 October 2026.

The verdict

Choose SlidesAI if you want to start free and you will pay for a yearly plan. Choose Decktopus if you need PDF, PPT and PNG output with a large monthly credit allowance and you are willing to pay monthly. On annual billing, the two Pro plans sit within a few cents of each other, so the yearly cost does not separate them.

What the pricing pages show

Where SlidesAI is stronger

The only zero-cost plan between the two belongs to SlidesAI. The Basic plan lists 12 presentations a year and 1,000 characters of input per presentation, with 120 AI credits per year. That is a real trial, not a teaser, if you only build a dozen decks a year. Its homepage describes building and editing inside Google Slides, PowerPoint or ChatGPT, which means the output is already in the file format your audience opens. The page also mentions a brand kit that you set up from an existing PPT file.

Where Decktopus is stronger

Decktopus lists more export options on its entry paid plan. The Pro plan includes PDF, PPT and PNG export, and it lists 750 AI credits a month, which the page estimates at roughly 150 slides. Its Business tier adds a shared workspace, a brand kit, slide analytics and a custom domain, with 1,000 AI credits per seat. The Business price was not captured in full, so this page does not compare it with SlidesAI’s Premium tier on cost.

Why the yearly bills match

The two Pro plans charge almost the same amount for a full year. SlidesAI’s listed US$120 and Decktopus’s US$119.88 differ by twelve cents. The gap appears when you pay monthly: Decktopus’s monthly Pro price is US$24.99, while SlidesAI’s Pro is shown only with a yearly bill in the captured text. A buyer who wants flexibility and can afford the monthly rate should read Decktopus’s monthly line before deciding.

Pick by starting point

• Choose SlidesAI when you want a zero-cost start, your decks are few, and you work in Google Slides or PowerPoint.
• Choose Decktopus when you need a PDF or PNG copy alongside the PPT file, and your monthly volume fits a 750-credit allowance.
• If you run a team, read both team tiers in full before buying. Decktopus’s Business price was not captured, so verify it on the live page.

Evidence and method

Both sets of figures were read off the two pricing pages on 17 October 2026. SlidesAI’s watermark terms and Decktopus’s watermark terms were not stated in the captured text, so this page makes no watermark claim for either. The annual figures are the figures the pages print.
