Beta — already in testers' hands

The AI email assistant for after triage is done.

Plenty of AI tools help you process your inbox faster. FilsOnly's job starts once that's done — remembering which threads you meant to follow up on, and nudging you before they go cold.

A different kind of AI assistant

Most "AI email assistants" help you process email. Not follow up on it.

Search "AI email assistant" and you'll mostly find tools built to triage, summarize, and draft — sorting the urgent from the unimportant, or writing a reply faster once you're looking at a message. That's a real problem, and Gmail and Outlook are already building it in for free. It's not the problem FilsOnly is built to solve.

FilsOnly's job starts after triage is done: watching the threads you already decided mattered, and remembering the ones you meant to get back to but didn't.
