What our research says

RewriteBar

RewriteBar is a good fit for a macOS user who wants AI rewriting available by keyboard shortcut in any app rather than pasting text into a browser tab, and the one-time price is a genuine alternative to a subscription. The catch is it's Mac-only with no Windows or iOS version, and it's a single developer's product rather than a team with a support desk.

Pros

  • Works inside most macOS text fields via a keyboard shortcut
  • One-time purchase instead of a subscription
  • Free trial credits with no card required
  • Built-in custom rewrite workflows beyond tone and grammar presets

Cons

  • macOS only, no Windows or iOS version
  • Built and maintained by a single developer

Wordtune

Wordtune still does the one thing it was built for better than the general assistants do, but its owner is in visible trouble and the product has not shipped news in two years. Cheap and useful today, risky as a dependency.

Pros

  • Rewrites preserve intent instead of paraphrasing into something else, which is the whole point
  • In-place browser extension avoids the copy-paste round trip
  • Cheapest tier is under $5 a month on annual billing

Cons

  • Parent AI21 Labs is in financial distress: a $300M round never closed, acquisition talks with NVIDIA and then Nebius, and reported layoffs above 60%
  • The product blog has not been updated since June 2024 and the site footer still reads 2025
  • AI21's own site no longer mentions Wordtune anywhere, suggesting it is no longer a strategic product
  • Free tier's 10 rewrites a day is exhausted in a single editing session

Which one fits

Choose RewriteBar if you need

  • macOS users who want rewriting available system-wide by shortcut
  • Anyone who prefers a one-time purchase over another monthly subscription

Choose Wordtune if you need

  • Non-native English writers who need a sentence to read naturally, not be rewritten wholesale
  • Anyone editing inside Gmail, Docs or LinkedIn who wants suggestions in place
  • Light users, since the free tier is genuinely usable for occasional rewriting
