Message Mediator

Write better anywhere

The MessageMediator extension underlines what you write, one paragraph at a time, in Gmail, Outlook, LinkedIn, Facebook, X, Slack, WhatsApp, Discord and almost any text box. Click a paragraph, choose More formal, More polite or More concise (any mix, or none for a perfect-grammar polish), then press Revise. Only that paragraph changes, right where you wrote it.

How it works

  1. Type as usual. Each paragraph gets its own subtle underline.
  2. Click a paragraph. A small box opens with three options.
  3. Press Revise. The paragraph is rewritten in place. Ctrl+Z (Cmd+Z) undoes it.

Same MessageMediator guardrails

Perfect grammar every time, your meaning kept, nothing invented: no new facts, promises or admissions. Heated wording is calmed, never sharpened.

Private by design

Nothing is sent until you click Revise, and then only that one paragraph. We do not store your text. Password, payment and one-time-code fields are never read, banking and health sites are off by default, and you can switch any site off or pause everything. Read the extension privacy policy.

Free and paid

Free accounts get 5 revisions a day (up to 50 a month). With a MessageMediator plan or credit pack, each revision uses 1 credit from your balance, so a Plus plan covers hundreds of revisions a month. See plans.
