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

Unbotify

Unbotify trains on your own writing rather than paraphrasing toward a generic 'human' style, which makes it more useful for everyday email and social replies than detector-dodging humanizers. At $9 a month the Pro plan is cheap, but the free tier is only ten rewrites ever, so it is a short trial rather than a plan. Skip it if you need a team product, an API or a vendor with a named company behind it.

Pros

Builds a style profile from real writing samples instead of paraphrasing to a generic tone
Writes first drafts from rough notes, not only rewrites of existing text
Works inside Gmail, LinkedIn, X, Instagram, Slack and Google Docs through the Chrome extension
Pro at $9 per month includes 5,000 writes and rewrites

Cons

Free plan is 10 writes and rewrites in total, not per month
No legal entity or country named in the terms of service
Chrome-only extension; no desktop or mobile app found
