Business Writing Agent

Ready-to-send emails, proposals, quotes and payment reminders in your tone.

Say what you need to send, who will read it and what you want them to do. It writes a ready-to-send draft with a subject line, matched to the relationship: warm for a new client, polite but firm for an overdue invoice. Paste your own draft and it makes it shorter and clearer without changing your facts.
