What our research says

AI Paragraph Generator

A no-signup utility for when you need a few paragraphs and do not want to open a chat assistant. The free path genuinely works, at the cost of ads and captchas. The paid tier is priced as an impulse buy by the week, which is a pattern worth noticing: weekly billing on a writing tool adds up to more than most monthly subscriptions over a year.

Pros

  • Works with no signup and no payment on the free path
  • About sixteen writing modes and 13+ output languages
  • Bundles a rewriter, summariser, expander and grammar check on the same site
  • Premium is cheap in absolute terms at $8.97 a month

Cons

  • The free tier is gated by ads and captchas and capped on word count
  • Weekly billing at $4.99 works out far more expensive than the monthly plan
  • No company name, country or legal entity published
  • No API, integrations or saved workspace

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
