Fyxer and Jace charge $30–50/month to "manage your inbox." I wanted to know what's actually under the hood.

Spoiler: it's prompt engineering + Gmail API + a thin wrapper+ some embedding for context . No magic. So I built the same thing properly and open-sourced it.

- Labels mails directly as they arrive in Gmail/Outlook UI. - Context window for draft and also calendar integration - Custom labels for your workflow

More integrations coming soon

Happy to share exactly what I found in their flows, ask anything.
