What our research says

TLDR This

A single-job summariser that still earns its keep as a browser extension for triaging long articles. As a paid subscription it is hard to justify now that general assistants and Chrome's own built-in summariser do the same job inside tools you already have.

Pros

the extension summarises the page you are on in one click, with no copy-paste
handles URLs and PDFs, not just pasted text
a documented API exists for embedding summaries in other products
unlimited free key-sentence summaries cover casual reading

Cons

the core capability is now commoditised by general assistants and browser-native summarisers
the site sits behind aggressive bot protection, which makes verification and monitoring awkward
no visible company details, changelog or roadmap
output quality swings a lot depending on how the source page is structured

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

Which one fits

Choose TLDR This if you need

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
