Operon reads the documents your plant runs on — P&IDs, isometrics, line lists, compliance records — and turns them into one live, queryable context layer for search, compliance, and AI agents.
Backed by Y Combinator

Equipment, lines, loops, and instruments extracted from every P&ID — and connected across sheets into one typed graph.
Ask in plain language. Get the tag, the sheet, and the exact region of the drawing the answer came from.
Revisions, verifications, and corrections logged as they happen — audit-ready by default, not by scramble.
01 / P&ID Recognition
Drop in any drawing from any decade: scanned P&IDs, faded isometrics, PFDs, line lists. Operon detects every symbol, tag, and connection with a per-tag confidence score, and your engineers verify sheet by sheet before anything reaches your systems.

02 / Knowledge Chat
Search thousands of sheets in plain language. Every answer resolves to real context — the tag, the line, and the drawing region it came from — so your engineers trust it enough to act on it.

03 / Compliance Documents
LDAR audit responses, MOC packets, HAZOP revalidation records — drafted from the live graph with tag-to-drawing traceability behind every line, and reconciled against your registers before anyone signs.

04 / Agentic Workflows
Material take-offs counted across thousands of sheets. Revision deltas flagged for MOC. Coverage checked before every audit. Agents read the same verified graph your engineers signed off on — and every action is logged.
REST · GraphQL · SDK · audit log


Equipment, lines, loops, and instruments as first-class objects — with cross-drawing connectivity and revision deltas between versions.
Raw model output never reaches your systems. Per-tag confidence routes low scores to review, and the graph records who verified what.
REST, GraphQL, and SDK on the same layer. Build your own applications — or let partners and integrators ship theirs on your graph.

Use cases
Buyers don't search for a data layer — they own a workflow and are measured on it. These run on Operon today.
EHS
Defensible tag-to-drawing traceability for LDAR, BWON, and audit responses — in minutes, not weeks.

PHA
HAZOP and PHA revalidation with every P&ID current, cross-referenced, and queryable.

MTO
Counts of every valve, fitting, and instrument across thousands of sheets — bid faster, scope tighter.

BROWNFIELD
Decades of scanned drawings become a living asset register with revision history.
MOC
Every change between drawing revisions, flagged automatically and tied to its source region.

AGENTS
Your engineers ask the plant questions in plain language; agents answer from the graph.

BUILT FOR THE PLANTS THAT NEVER STOP.
Deployment & security
Procurement and IT clear this section before you ever have to ask.
An isolated tenant per customer — the fastest path from a folder of scans to a working graph.
The engine runs inside your network. Documents never leave your perimeter.
Send us a handful of sheets from your plant. Within the week you'll be querying your own P&IDs as a live graph — no slide decks, no sample data.
