Email triage with Jev
Every new email is classified into 11 categories (clients, recruiting, finance, security, newsletters…) and labelled in Gmail, with a Needs Reply flag on the ones a real person is waiting on. Uses TypeSafe's Jev decision model instead of a chat LLM, so it's fast and near-free: on a real inbox it categorized 127 emails in 6 seconds for $0.0056 total.
Useful for keeping any inbox sorted without reading it first, at about $0.04 per thousand emails.
