Clean Up
Fix your writing. In the app you wrote it.
Select what you just wrote, press one keyboard shortcut, and Echo fixes the grammar, the spelling and the phrasing that came out wrong — then writes it straight back over your text. Your voice stays yours.

How to fix grammar in any app on a Mac
Select what you wrote
The Slack message, the email, the paragraph in Notion. Anything that reads slightly off and that you would rather not rewrite by hand.
Press your shortcut
Press 3 for Clean Up. Echo corrects the mistakes and the clumsy phrasing, and leaves the meaning and the tone alone.
It lands back in place
The corrected version goes straight back over your selection. No copy-paste, no rewriting the message in another window.
Everywhere you write, not just one text box
Grammar tools usually live inside one editor, or in a browser extension that only reaches web pages. Echo works on the selection, so every app on your Mac is covered the same way.
Slack and Messages
The quick message you would otherwise reread three times before pressing enter.
Mail and Outlook
The email where a typo would be noticed, cleaned up before it goes out.
Notion and Docs
Fix the paragraph you are in without breaking your writing rhythm.
Native Mac apps
Notes, Pages, Craft, Bear — the apps a browser extension never reaches.
Code editors
Comments, commit messages, READMEs and documentation, in the editor itself.
A second language
Write in a language that is not your first with the mistakes caught before anyone sees them.
Questions
Select the text you want corrected, press your Echo shortcut and choose Clean Up. Echo writes the corrected version straight back over your selection, in whichever app you are in.
No. Clean Up fixes grammar, spelling and awkward phrasing and leaves your voice alone. If you do want a different tone, you can type your own instruction and ask for it explicitly.
Extensions only reach web pages. Echo reads the selection through macOS itself, so it works the same in native apps — Mail, Notes, Slack, Pages, a code editor — as it does in a browser.
Yes. Echo cleans up text in the languages a large language model handles well, French included, and leaves it in the language you wrote it in.
Never. Echo only reads and replaces what you highlighted. The rest of the document is untouched.
No. Your text stays in memory for the length of the popup interaction, is never written to disk, and is never logged.
