About Qrtr

Built by people who’ve held the red pen

Qrtr is built by engineers, reviewers, auditors and approvers who spent decades doing review the hard way.

Why we built Qrtr

Between us, we’ve had reports handed back covered in red pen, chased comment bubbles through tracked changes, audited other people’s work and signed our names to deliverables.

Every firm we worked in had the same problem. The review was where quality was decided, but the record of it lived in marked-up Word files that nobody could search, and sign-off depended on trust rather than evidence.

We kept thinking there had to be a better way to review and approve technical reports. Qrtr is it.

What we’re building

AI that supports professionals rather than replaces them. Qrtr gives reviewers evidence and a clear record. People make the call.

What we believe

01

People decide

Qrtr gives reviewers evidence. People accept or reject every finding, and the record shows who decided.

02

Every decision on the record

Who raised what, what changed and who signed it off is kept, so review can be shown, not just claimed.

03

Only claim what we can check

Qrtr checks what it can verify against a requirement set. It does not guess what good looks like.

04

Work where engineers work

Authors stay in Word. Reviewers use a browser. Nobody changes how they write to use Qrtr.
