What our research says

Grammarly

Still the default for catching mistakes inside other people's software, but the free tier has quietly become an AI-prompt meter and the honest price is $30 unless you commit to a full year.

Pros

  • Runs inside the apps people already write in rather than as a separate editor
  • Free tier still covers spelling, grammar and tone detection with no time limit
  • Pro folds in plagiarism and AI-text detection that rivals charge for separately

Cons

  • The $12 headline is the annual rate; paying monthly costs $30
  • Free AI allowance is 100 prompts a month and depletes quickly
  • No public API, so it cannot be embedded in another product
  • Enterprise pricing is not published anywhere on the site

TextWisely

TextWisely's main selling point is that it lives in the menu bar and reaches into whatever field you're typing in—Mail, Slack, Notes—instead of asking you to paste text into a separate site. For people who write across many native Mac apps that saves real friction. It's Mac-only and needs a fairly recent macOS version, and unlike most competitors it doesn't offer a running free tier, only a refund window.

Pros

  • Works inside any macOS app instead of a separate browser tab
  • One-time $29 license is available instead of a subscription
  • Supports 39 languages with customizable tone presets

Cons

  • macOS only, and only on Sequoia (15.0) or newer
  • No running free tier, just a 14-day money-back window
  • No company name or address published beyond a contact form
