FilsOnly connects to Outlook or Gmail, quietly tracks the threads that matter, and nudges you before something falls through — days later, not in the moment you'd have noticed anyway.
FilsOnly coordinates the process without maintaining a central copy of your inbox — each connection runs directly between your device and the service on the other end, using your own sign-in and your own API key.
Your inbox app already sorts urgent from unimportant. What it doesn't do is remember that you never actually replied — until you're the one who has to notice.
