Melampus

Melampus is a private personal assistant that runs on its owner's own computer. It helps with everyday work: reading his inbox, preparing email drafts, finding businesses that need a website, and summarising study material.

It is not a public service and has no other users. The Google sign-in ("Melampus Outreach") is used only by its owner, for his own Gmail account.

What it does with Gmail

It shows the owner's recent messages inside the app and creates drafts that he reviews and sends himself. It does not send email on its own.
