What our research says

Beautiful.ai

Buys you consistency rather than creativity — the layout engine stops non-designers producing ugly slides, which is worth real money in a sales org, but you are locked into its idea of what a slide is.

Pros

  • Smart-slide rules genuinely prevent the usual amateur layout failures
  • Brand locking and shared libraries make team consistency the default, not a review step
  • Long-established product rather than a recent generative wrapper

Cons

  • Month-to-month is roughly $45 against $12 on annual, so the headline price is a twelve-month commitment
  • Web-only, with no desktop or mobile app and no API
  • The layout engine resists you the moment you want something bespoke
  • No free tier — evaluation is a 14-day trial that wants a card

Slidely AI

Slidely's PowerPoint add-in and Excel-linked charts make it more useful for people who live inside Microsoft Office than a browser-only deck tool would be. The free plan is deliberately limited, with add-in access cutting off after 15 days, so it functions mainly as a trial rather than a lasting free tier. Enterprise-oriented compliance claims, including SOC 2 and GDPR, suggest it is aimed at business buyers as much as individuals.

Pros

  • PowerPoint add-in works natively inside Windows and Mac Office, not just the browser
  • Excel-linked charts and tables update automatically instead of needing re-export
  • Y Combinator backing and named compliance certifications add some outside verification

Cons

  • Free plan's PowerPoint add-in access expires after 15 days
  • Entry paid tier still requires a per-seat jump to Team pricing for collaboration
