A message that needs a little help.

Replaced

Three steps, and the third one is Return.

  1. Step 1

    Select any text

    Slack, Mail, Notion, your browser, a code review comment. Anywhere you can highlight.

  2. Step 2

    Press ⇧⌘E

    Three polished variants stream in under a second. Polite and correct by default, no menus first.

  3. Step 3

    Press Return

    The chosen variant replaces your selection right where it was. Or press C to copy it.

Change it after, not before.

Tone pickers make you decide before you have seen anything. Grammar Llama shows the polite version first and lets you react to it: click a chip or type a plain sentence. Tweaks stack and each one can be removed.

Small app. Considered details.

Results first, no tone menu
You see rewrites before you decide anything. Type “more casual” afterwards only if you want to.
Three variants, one key each
Minimal, Smoother and Concise. Press 1, 2 or 3. Regenerate one with R.
Edit before you send
Press E to tweak a word or two in place. A live diff shows exactly what changed.
Works where you type
Reads your selection through Accessibility and falls back to the clipboard for apps that hide it.
Your key, your Mac
Bring your own Anthropic API key. It lives in your Keychain. There is no account and no server in between.
Menu bar only
No Dock icon, no window to manage. Just a small llama waiting for a shortcut.
