inbox-zero

What it does

An email assistant that organises the inbox, pre-drafts replies matching your tone, tracks what still needs a response versus what is waiting on someone else, and takes handling rules in plain English rather than filter syntax. Reachable from Slack or Telegram, self-hostable or hosted. The trade-off is unavoidable: your mail passes through whichever model you configure, which is a policy question at work before it is a technical one. Read drafts before they go. AGPL-3.0.
