One source of truth for every drawing you own.
Put every engineering drawing under revision control, keep it searchable for the life of the asset, and run it with your own team.

The drawings outlast every system you keep them in.
You hold tens of thousands of drawings across decades of buildings, plant, and infrastructure. The tools were built to be switched off at handover, not to run for the decades you operate the asset.
Lunr fixes the record, not the symptom. One system from project delivery through decades of operation, run by your own team.
- The latest revision is on a network drive, in an email, or in someone's head.01
- Contractors sign off at practical completion. Half the as-constructed set never arrives.02
- Search reads the filename, not the drawing. The valve tag inside a scan is invisible.03
- An audit asks for the controlled version. You hope the one you found is it.04
- The last EDMS needed a consultant to change a workflow and a specialist to keep it running.05
Purpose-built for drawings. Not a folder you have to police.
Every revision under control, from delivery through operation.
Controlled documents, approvals, handover, and a full audit history, with automated document and version numbering, so REV C is always REV C and never the file someone renamed. The record runs from project delivery through the decades you operate the asset. Classify by folder, tag, and portfolio, then set tag-based permissions so people see exactly what they should.

Search the text inside the drawing.
XRAY runs OCR and AI across everything you store, so a valve tag from a 1994 scan turns up as fast as a file you saved this morning. For a dense drawing, Deep XRAY re-reads the sheet in high-resolution tiles, from 2×2 up to 4×4, so faint or crowded text still resolves. No incumbent leads here. Their search reads the filename. Filter by tag, or find geo-tagged drawings on a map with polygon search from your GIS.

Keep the record clean.
Run project spaces with RFIs and transmittals, a common data environment (CDE) when your projects require one, and redline drawings in Signal without leaving the browser. Contractors and consultants join as Collaborators and see only what you grant them.
