Alternatives
Tried everything else for
engineering document extraction?
Manual teams, BPOs, generic OCR, and in-house AI projects all have their place. Here's an honest look at when each works — and when they don't.
Manual Extraction Teams
3–6 months for 1,000 P&IDs. Human fatigue drives accuracy below 90%. No reconciliation across documents. Knowledge walks out the door when contractors leave.
When it works:
Small projects under 50 drawings with low accuracy requirements.
The limitation:
Doesn't scale. Cost per drawing increases with project complexity.
Offshore Document Control BPOs
Lower cost per hour, but total cost is higher due to QA rework cycles. 2–4 week feedback loops. No engineering domain expertise — operators follow templates, can't interpret ISA 5.1 or ASME standards.
When it works:
Simple data entry tasks with clear templates and low stakes.
The limitation:
Engineering documents require domain judgement that template-based BPOs can't provide.
Generic OCR / AI Tools
Trained on invoices and receipts, not engineering drawings. Can't parse P&ID symbology, line connectivity, or instrument loop relationships. 70–85% accuracy on engineering documents — the remaining 15–30% requires manual cleanup that often takes longer than doing it from scratch.
When it works:
Typed text extraction from standard business documents.
The limitation:
Not trained on ISA 5.1, ASME Y14.5, or AIAG FMEA standards. No reconciliation capability.
In-House AI Development
12–18 month development timeline. Requires ML engineers who understand both deep learning and engineering standards. Training data curation alone takes 6+ months. Most internal projects stall after the proof-of-concept.
When it works:
Large enterprises with dedicated AI teams and 2+ year horizons.
The limitation:
By the time it's production-ready, the project that needed it has already shipped.
The Pathnovo approach
We combine AI models trained specifically on engineering standards with domain-certified engineers who review every output. The result: 99.5% accuracy at 10x the speed of manual teams, with direct delivery to your enterprise systems.
99.5% accuracy SLA
Contractual, with remedy clause. Not a marketing claim.
48-hour free pilot
Send 10 documents. See results before any contract.
10x faster delivery
1,000 P&IDs in 2–3 weeks, not 3–6 months.
See what your documents actually contain.
Send us 10 documents from your current project. We extract, reconcile, and show you exactly what we find in 48 hours, before any contract.
If the accuracy isn't what we promised, you owe us nothing.
