Composed automatically — ready for your review.

One movement, from work to invoice.

Nothing slows a professional like tracking their own time. So the instrument does it for you — reading the day’s work as it progresses and setting it into billable entries, the way a fine movement turns motion into time.

  1. 01

    Capture

    The mechanism watches the work you already do — calls, mail, documents, meetings — across the tools your firm runs on.

  2. 02

    Classify

    Frontier intelligence reads each moment for what it was, whom it was for, and whether it is billable — no timers, no forms.

  3. 03

    Crystallize

    Each moment sets into a clean, editable entry: narrative, matter, and duration, to the minute.

  4. 04

    Bill

    Entries flow straight into invoices and reports, ready for your review and your client’s.

The complications.

Three mechanisms, one instrument — capture, billing, and the intelligence to steer a firm. Each precise on its own; together, they run the practice.

AI Timesheets

Time tracked as you work

Accurate, contemporaneous entries — narrated, matter-coded, and billable — generated from the work. Review, adjust, done.
