What Wordtune is
Wordtune, from AI21 Labs, became popular for one clever idea: highlight a sentence and get several better versions of it. You can make it more casual or formal, shorter or longer, and it can suggest additions such as examples or explanations. It works inside Gmail, Google Docs, LinkedIn and most places you type, and has its own web editor.
It suits people who write their own messages and want help finding a better phrasing.
What AI Reply Writer is
AI Reply Writer starts earlier, before you have written anything. Its ✦ AI Reply button reads the message you are answering and drafts the full reply in your chosen tone and length. You can steer it with a few words — "accept, ask for Friday instead" — then edit and send.
- Reads the other side — the thread, the comment, the review and its stars, photos and PDFs.
- In each app's reply box across 23 sites, including WhatsApp Web, Instagram, Facebook, Slack and Teams.
- Can also polish: type a rough version of what you want to say, and it writes it properly.
The main differences
Where you start
Wordtune needs your sentence first; AI Reply Writer needs only the message you are replying to. For routine replies, starting from a draft is faster. For carefully worded messages you want to write yourself, rewriting suggestions keep your voice.
Context
A rewrite tool sees your sentence. A reply tool sees the whole conversation — which is what lets it answer the actual question someone asked.
Polishing
