Measure off PDFs

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.

Optional AI assist

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.

Export ready to price

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.

Built for the way Estimators actually work

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.

Made by an Estimator, for Estimators. Currently in closed beta with a small group of testers. If you'd like to join, get in touch.
