Overview

About Wordtune

Wordtune proposes different ways to phrase whatever sentence you highlight, with sliders for length and formality, and it runs as a browser extension over editors you already use. Long documents can be summarised, and spelling and grammar are checked as you type. The free tier caps rewrites at ten a day, which is the limit most users meet first.

Editorial verdict

Pros & cons of Wordtune

medium confidence

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

Best for

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

Not for

Drafting from scratch, which a general assistant does better for the same money
Organisations that need a vendor with a stable roadmap and support commitment

Watch out: Several secondary sources claim Wordtune was shut down in April 2025. That is wrong as of 2026-08-17: the site sells plans, the Chrome extension is still published and Wikipedia records no closure. The real risk is not that it is dead but that it is unmaintained under a distressed parent, so do not build a workflow that cannot survive its withdrawal.
