Wordtune
Wordtune is AI21 Labs' writing companion, built around rewriting rather than generating: take a sentence you have already written and see it again in different tones and shapes, casual to formal, shorter to expanded, until one says it better. Suggestions arrive as alternatives to choose between rather than prose to accept, which keeps the writer's judgement in the loop.
Around the rewriting core sit spelling and grammar checks, AI summarisation of longer material, and browser and editor integrations that bring the suggestions to where writing happens. A free tier covers light use within daily and monthly allowances on the AI features; paid tiers lift the limits.
It suits people who write plenty and want their own sentences improved, not replaced. AI21's own marketing now leads with its enterprise model business, but Wordtune remains live, priced and signup-open as its consumer writing product.

Best for
- Rewriting your own sentences across tones and lengths
- Choosing between suggested alternatives rather than accepting prose
- Spelling and grammar checking alongside the rewrites
- Summarising longer material with AI
- A free tier for light daily rewriting
Less suited to
Wordtune improves sentences that exist; drafting from a brief, research and long-form generation belong to the general assistants. Teams needing brand governance, terminology enforcement and approval workflow are shopping for a platform, not a companion.
The free tier's daily and monthly allowances suit light use by design; anyone rewriting all day will meet them quickly, and the paid tiers are the answer the vendor intends.
Costs & data, in short
A free tier carries daily and monthly allowances on the AI features, with paid individual tiers above it that raise or remove them; annual billing is cheaper than monthly.
Text you rewrite passes through the vendor's cloud under its terms, so check policy before pasting confidential or client drafts into it.

In practice
How Wordtune is used, area by area.
Jobs
Getting started
Wordtune is one of the gentlest first steps into AI writing because it never takes the pen. You write the sentence; it offers versions; you choose. That shape teaches what AI suggestion feels like without the blank-page delegation that makes new users distrust generated prose, and the spelling and grammar layer makes it useful from the first day. The free tier's allowances cover exactly the light, occasional use a beginner starts with.
Example tasks
- Rewrite a sentence in a more formal or casual tone
- Shorten a sentence that runs long
- Expand a thin sentence with more substance
- Check spelling and grammar as you write
- Summarise a long article before deciding to read it
Limits
Drafting whole documents from a brief is the general assistants' job, not a rewriter's.

Tasks
Writing & research
On a hub full of tools that write for you
On a hub full of tools that write for you, Wordtune's place is the one that makes you a better version of yourself. It sits in the rewriting niche beside the paraphrasers and checkers: sentence-level suggestions across tone and length, grammar and spelling underneath, summarisation for the reading half of writing work. The judgement stays with the writer, which is precisely what some work requires, personal messages, applications, anything where generated voice would ring false. AI21's enterprise pivot has moved Wordtune out of its own homepage spotlight, but the product remains live, priced and maintained.
Example tasks
- Improve an important email before sending
- Rework an application or bio sentence by sentence
- Adjust tone for a different audience
- Fix grammar without changing the voice
- Summarise sources while researching a piece
Limits
Volume content production and brand-governed writing belong to the platforms built for teams.
