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

Plagiarism Remover

Does what it says, rewriting a flagged passage into text that reads differently while keeping the meaning, and Pro now starts at $4.99 a week or $9.99 a month, cheap enough for occasional use. Paid plans also bundle plagiarism-checker runs, so you can check and fix in one place, but the free tier's 1,000-word cap and ads make it a trial rather than a working tool.

Pros

  • four distinct rewrite modes instead of one generic pass
  • Pro plans from $4.99 a week, with monthly and yearly options
  • paid plans include plagiarism-checker submissions alongside rewrites
  • exports to plain text or Word

Cons

  • free tier caps input at 1,000 words and shows ads and captchas
  • paid plans still cap each submission at 3,000 words and count submissions
  • no company name is published anywhere on the site

Which one fits

Choose Grammarly if you need

  • Anyone writing in a browser, Word or email who wants corrections in place

Choose Plagiarism Remover if you need

  • students or writers who already know which passage was flagged and need it rewritten
  • short rewrites where a 1,000- to 3,000-word cap per submission is enough
