The briefing: the three threads that most need you, each with the reasons it was picked.

Ask it about your mail

coming in Think

Press c and ask in plain language. posture searches across every account, answers with the messages it used, and drafts what you need in your own voice. Anything it writes waits for your approval.

> You: Investigate the insurance billing.
  Harbour Mutual collected the October premium of R 4,812.50 twice. You reported the duplicate debit
  and they opened query HM-QRY-58213, but their records show only one collection and they are asking
  for a bank statement. Their latest message says the query will be closed if they do not receive
  it.

  Nothing in your mail shows a refund so far. I have drafted a dispute email that quotes both
  collections and asks for the second to be reversed. It is waiting for your approval; you would
  need to attach the statement page.

Your mail stays yours

posture has no server. There is nothing between your computer and your mail provider.

Straight from your provider to your machine. Mail is fetched by the app on your computer and nowhere else.
Stored locally. In a database file only your user account can read.
Sign-in kept in your keychain. Tokens never sit in a plain file.
Your password stays with your provider. You sign in on your provider's own page, so posture never sees your password.
Read-only today. The current version never changes anything in your mailbox. No analytics, no telemetry.

3 · Act

Tell it what to do: archive, label, reply, send. Nothing happens until you approve, every action passes fixed policy checks, and all of it is logged.

Coming soon

posture is being tested now. The source will be published on GitHub under an open-source licence. Until then, questions go to hello@posture.email.
