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

Wordtune

Wordtune still does the one thing it was built for better than the general assistants do, but its owner is in visible trouble and the product has not shipped news in two years. Cheap and useful today, risky as a dependency.

Pros

Rewrites preserve intent instead of paraphrasing into something else, which is the whole point
In-place browser extension avoids the copy-paste round trip
Cheapest tier is under $5 a month on annual billing

Cons

Parent AI21 Labs is in financial distress: a $300M round never closed, acquisition talks with NVIDIA and then Nebius, and reported layoffs above 60%
The product blog has not been updated since June 2024 and the site footer still reads 2025
AI21's own site no longer mentions Wordtune anywhere, suggesting it is no longer a strategic product
Free tier's 10 rewrites a day is exhausted in a single editing session

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

Non-native English speakers who want fluency rewrites, not just error flags

Choose Wordtune if you need

Non-native English writers who need a sentence to read naturally, not be rewritten wholesale
Anyone editing inside Gmail, Docs or LinkedIn who wants suggestions in place
Light users, since the free tier is genuinely usable for occasional rewriting
