About Email writer
The emails that are hardest to write are often short: asking a stranger for something, answering a message you've let sit too long, chasing a reply without sounding pushy. The email writer drafts all three. Choose New email for a first or cold email, Reply to answer a message you paste in, or Follow-up to nudge an earlier one, then say in a sentence or two what you want to get across.
Pick a tone (professional, friendly, formal, persuasive or apologetic) and a length: short is about 50 to 90 words, medium 100 to 160, long 180 to 250. Claude, Anthropic's AI model, writes a subject line and a body with a greeting and a sign-off. Anything you didn't tell it, such as a name, a date or a price, appears as a [placeholder] rather than being made up, so the draft never promises something you didn't say.
When it reads right, copy it, save it, or press Open in email app to start a message in your own mail program with the subject and body filled in; nothing is sent from this page. The draft follows the language of your notes by default, or you can choose one of sixteen languages.
The writer doesn't know your relationship with the recipient or your company's house style, so read the draft once and adjust it. Don't paste passwords, account numbers or other private data you wouldn't put in an email to a stranger.
Privacy
Your notes, and for a reply or follow-up the email you paste, are sent only when you press Write email: to our server, then to Anthropic's API to write the draft. None of it is stored or logged by us, and Anthropic doesn't train models on API data. Open in email app hands the draft to your own mail program on this device; the page itself sends no email. Option choices are kept in this browser.
