Tagsight Technologies Inc. builds independent engineering software for the engineers, project managers, and integrator teams who carry the documentation load on any project that ships engineering drawings.
Three drawings included on a new account.
Tagsight reads the full bundle of engineering drawings and schedules a project carries, the P&IDs, SLDs, loop diagrams, SAMA charts, instrument datasheets, cable and junction-box schedules, hookup details, motor lists, MCC and HVAC schedules, and other project tables, into the instrument index, I/O list, and tag register a project runs on. How far each document type is supported is stated below, not implied.
Every register is reconciled across documents, so the team settles orphans, phantoms, mistermination, and attribute disagreements while the drawings are still under review. Outputs ship in the formats downstream tools already use.
Each class of document and what it produces. An engineer confirms every row before anything is issued.
| Documents | What it produces |
|---|---|
| P&IDs | The instrument index, I/O list, equipment, line and valve lists, alarm and trip schedule and SIF register, reviewed on the sheet; revision comparison and change report; every export format. In production since April 2026. |
| Single-line diagrams, loop diagrams, SAMA charts | Registers from each diagram, reviewed against the sheet, with exports to Excel, CSV and JSON. |
| Cause-and-effect matrices, cable and junction-box schedules, datasheets, instrument indexes, motor, MCC and HVAC schedules, other project tables | Read into the registers and checked against the drawings during review, with exports to Excel, CSV and JSON. |
Tagsight is not certified, validated, or qualified for use in functional safety applications. Safety registers it produces are drafts for the project's own review.

Front-end loading and detail engineering lose the most time to two things: transcribing tags from drawings into spreadsheets by hand, and reconciling the same instrument across the P&ID, the datasheet binder, the cable schedule, the loop diagram, and the JB schedule when one document says PT-101 measures 0-100 psi and another says 0-150 psi. Tagsight reads every document, classifies the signals, and surfaces the disagreements to settle before construction.
Tagsight reads drawings produced in any CAD tool, AutoCAD Plant 3D, AVEVA, SmartPlant, or Bentley OpenPlant, and produces the structured documents those tools leave for the team to build by hand. It reads brownfield scans and fresh vector exports the same way, across the project lifecycle from front-end loading through commissioning, on both retrofits and greenfield builds.

A carbon capture unit is an amine system. An electrolyzer plant is compression, storage, gas detection and a great deal of water treatment. A battery plant is a one-line, HVAC, fire suppression and a thermal-management P&ID. Each is documented as any plant is, in ISA, KKS, IEC 81346 or the owner’s own convention, and each runs on the instrument index and I/O list that are still built by hand from the sheets.
The retrofit side is the same work in the other direction. Electrification, a capture tie-in or hydrogen blending begins with the current-state record of an existing unit, read from drawings that are often decades old and scanned. Tagsight builds that record for both: the new plants, and the refineries and gas plants being rebuilt around them.

Used across process plants, utilities, facilities, and capital projects, by the people building I/O lists, instrument indexes, motor lists, cable schedules, MOC packages, and SIL evidence packages.
Upload a drawing set and read the instrument index and I/O list it returns, reconciled across every document in the bundle.
