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.
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.

AI that supports professionals rather than replaces them. Qrtr gives reviewers evidence and a clear record. People make the call.
What we believe
People decide
Qrtr gives reviewers evidence. People accept or reject every finding, and the record shows who decided.
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.
Only claim what we can check
Qrtr checks what it can verify against a requirement set. It does not guess what good looks like.
Work where engineers work
Authors stay in Word. Reviewers use a browser. Nobody changes how they write to use Qrtr.
