Treble is an AI work companion, helping you stay ahead of priorities, projects, and deadlines. (treble.io)

Treble is an AI work companion that connects to your email and turns daily communication into an organized, actionable task system. It’s built for busy professionals (real estate agents, transaction coordinators, legal professionals, etc.) who need to stay on top of commitments, deadlines, and follow-ups without constant manual tracking.

Treble automatically extracts tasks from your emails and conversations, then keeps them prioritized so you always know what matters most right now. Tasks are grouped by context (project/client/topic), updated as new information comes in, and kept clean as items are completed or no longer relevant - so your list stays usable instead of becoming another inbox.

To keep you proactive, Treble tracks follow-ups and surfaces conversations that need a reply, along with the key context you need to take action quickly. It also delivers a Daily Brief each morning with a recap of what changed while you were away and the highest-priority tasks to tackle first, helping you start the day aligned and in control.
