What our research says

Free AI Essay Writer

It genuinely does generate a structured essay for free, in a dozen-plus citation styles, without asking you to register — which is more than most tools wearing the word free. The price is being marketed at: the page repeatedly pushes a callback form for a paid writing service run by the same people, and submitting your number is the actual product being sold.

Pros

  • Works with no sign-up, no card and no usage counter
  • Supports 15+ citation styles and several document types beyond essays
  • Word count and academic level are adjustable inputs
  • A separate outline generator is offered alongside the full-text tool

Cons

  • Aggressive lead-capture pop-ups asking for a WhatsApp number and a callback
  • Effectively a funnel to PerfectEssayWriter.ai, a paid service from the same operator
  • No legal entity named; only a street address and phone numbers

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
