Kestrel measures lengths, areas and counts straight off your drawings. Optional AI reads finish schedules and scales for you. Built for UK Estimators and small contractors.

Lengths, areas, counts. Pick a finish, draw, done. Scale auto-detects from the title block in most cases, or set it manually in a click.
Bring your own Anthropic API key. Claude reads finish-schedule legends, auto-names PDFs from their title blocks, and recovers scales when the built-in detector misses. Costs come straight to you, not via Kestrel.
Trade-grouped Excel with quantities, codes, descriptions. Annotated PDFs with a Take Off Legend and Quantity Key per page. Drawing register export for the audit trail.
No cloud lock-in. Your projects live as single .qtdb files on
your machine. No login required to take off; the licence checks in
online every few days. Windows now, Mac coming.
