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

Litero

Litero's pitch is source-anchored writing help rather than essay generation: outline, cite, and check a draft against 100 million-plus scholarly sources instead of asking the AI to write the whole thing. Its own AI-detector and humanizer-style features sit in some tension with each other, and buyers should weigh that combination against their institution's academic-integrity policy.

Pros

  • Citation tool draws from over 100 million sources including JSTOR and Google Scholar
  • Bundles outline building, grammar, plagiarism, and AI-detection in one subscription
  • Free tier is usable without a credit card before committing to Premium

Cons

  • Free plan's daily AI output cap will feel restrictive for longer writing sessions
  • The home page advertises only the annual-billing rate; monthly and quarterly prices appear only at checkout
  • Combining an AI detector with a humanizer-style feature raises academic-integrity questions worth checking against institutional policy
