In progressArmeta vs. generic OCR tools.
The most common confusion in the market is “can't I just use a generic OCR tool for this?” The short answer is no — and the reasons matter. Generic OCR reads text. A P&ID is an engineering document in which most of the information is encoded in symbols, topology, and convention.

What this page will cover
- 01Symbology interpretation — why an ISA-5.1 valve symbol, a PIP PIC001 instrument bubble, and an operator-specific library element are not character data, and why generic OCR can't resolve them.
- 02Cross-drawing connectivity — off-page connectors, equipment hierarchy, and the facility-level engineering graph a single-sheet OCR read cannot produce.
- 03Engineering context — service designation, line class, material of construction, and how Armeta attaches the right attributes to the right objects while OCR returns a flat text stream.
- 04Structured output vs. flat text — what a procurement team, an LDAR database, or a PHA-Pro import actually needs, and why an OCR PDF sidecar doesn't clear the bar.
- 05When OCR is part of the pipeline — Armeta uses OCR as one input signal among many. Standalone OCR is the wrong tool; OCR inside a multi-stage extraction engine is useful.
- 06The accuracy ceiling — where generic OCR plateaus on industrial drawings and why incremental accuracy on symbol recognition doesn't translate to usable MTO or PSI output.
Your drawings, your data
Start with ten of your own drawings.
Reference pages describe what Armeta does. The fastest way to know what it does for your team is to run it on your actual P&IDs.
