Unvent

Unvent is built around a single idea: the gap between what you type and what you wish you had typed should be closed with one key, not a detour to a separate tool. After you install the extension, you write your message however it comes out, press Ctrl+Shift+U (rebindable), and pick one of three tones. Polished is confident, warm and specific. Direct is tight and decisive. Warm leads with empathy. One more press applies the rewrite right where you typed it, inside the same compose box on Gmail, Slack, Linear, LinkedIn, Notion, Discord and any other editable field on the web. Nothing opens in a new tab and nothing needs to be copied across.

The other half of the product is Unvent Flow, which turns speech into a clean draft. You talk the way you think, the browser transcribes on your own device, and Unvent then tidies the result — trimming filler words and stutters — into something you can send. Because the transcription happens locally, your voice never leaves your machine, and the cleaned text is not stored. Drafts are not kept and are never used for model training, and the logging the app does perform is content-free.

Unvent runs on a freemium model. The free plan covers five rewrites a day, which is enough to test the habit on real messages. Paid tiers, Pro and Pro Plus, lift the daily limits, allow longer drafts, and add tuning for specific audiences such as a client, a manager or a cold prospect.
