Automatic time tracking that adds up your billable hours.
The desktop app records what you work on and sorts it into projects automatically. See your billable total, send a PDF invoice, and catch the hours you forgot to bill.
Three steps, and you never reconstruct a week again.
Capture
Install the desktop app once. It watches the active window and logs what you work on, second by second — no timer to start, nothing to remember. Connect a Google or Microsoft calendar and BillNotch reads your recent meetings, read-only, and suggests them as entries you approve.
Categorize
Activity sorts itself into projects by your keyword rules. Turn on AI categorization for the fuzzy cases. Billable is inherited from the project.
Bill
Read the billable total, send a PDF invoice, or export CSV. The Revenue Leak Finder flags billable time you never invoiced.
Everything from raw activity to an invoice-ready total.
Categorization on autopilot
Keyword rules (domains, app names, ticket prefixes) sort activity into projects out of the box. Add an AI key and the fuzzy cases get sorted too — billable when the project bills.
Built for you, not your boss
Sync window titles or keep them on your machine — your call, per device. Connect each one with an API key you issue and revoke anytime.
Billable, to the second
Every entry inherits its project’s billable rate, summed live into a total you can invoice.
Invoices & the leak finder
Totals by day and project, ready for a PDF invoice or a CSV export. The Revenue Leak Finder answers what’s still unbilled: billable time you tracked but never put on an invoice.

Start tracking the hours you can bill.
Set up the desktop app once. Your ledger keeps itself, your invoices write from the total, and the leak finder makes sure nothing bills late.
The short version.

No. The desktop app records the active window for you. You can still start a manual timer on the dashboard whenever you want one.
Keyword rules are deterministic and need no setup — that is the default. Add an AI key for the fuzzy matches; the rule-based categorizer stays the tested fallback either way.
Yes. Generate a PDF invoice from a project’s billable total, or export a CSV (activity, project, duration, billable flag) for any date range you pick.
It scans your tracked time for billable work that never landed on an invoice — unbilled entries, gaps, projects you forgot — so you can bill the money you already earned.
To your own BillNotch account, over an API key you issue and can revoke. You choose the sync mode per device — window titles can stay on your machine and never leave it. Data is processed on EU servers and never sold. Built for you, not your boss.
