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

PaperTyper

PaperTyper packages the basic academic-writing toolkit — essay drafting, plagiarism check, grammar check, citations — as free web tools with no account required, which makes it an easy first stop for a rough draft. The catch is that the free AI output is explicitly a starting draft, not submission-ready, and the site's real business appears to be upselling a paid human-writing service on top.

Pros

  • Four separate free tools (essay draft, plagiarism, grammar, citations) with no signup
  • Downloads as Word or PDF
  • Long-running site with visible third-party ratings on Trustpilot and SiteJabber
  • No paywall on the core AI essay generator

Cons

  • Site pushes a paid human-essay-writing service alongside the free tools
  • No company name, location, or team disclosed
  • AI draft explicitly needs editing before submission, by the site's own framing
