Turn legacy drawings into a connected plant model.
Novek transforms flat P&IDs into a queryable topological graph — connecting equipment, piping lines, valves, and instruments for CAD migration, AI agents, and project registers.
Legacy Drawings
Connected Model Graph
Multiple Outcomes
End-to-end model pipeline
From legacy drawing to verified engineering model
Five steps. No proprietary lock-in. Preserves 100% of spatial, attribute, and connectivity context for engineering software and AI.
Ingest drawing packages
Drop in scanned P&IDs, PDFs, TIFFs, or raster CAD files. Novek automatically identifies sheet boundaries, title blocks, symbology legends, and drawing grids.
Detect symbols & piping topology
Vision-AI models detect equipment, inline valves, instruments, piping segments, line numbers, and flow direction arrows matching standard or client legend sheets.
Construct connected engineering graph
Novek stitches together process lines, cross-drawing connectors (OPCs), instrument loops, and asset hierarchies into a unified topological model.
Engineer-in-the-loop review
Every extracted tag, connection, and attribute is highlighted on the original drawing with confidence scores. Engineers verify and sign off with complete audit trails.
Export to multiple downstream destinations
Deliver DEXPI XML (ISO 15926), SmartPlant P&ID imports, line lists, instrument indexes, or query the model directly via the Novek Context API.
Document Ingestion
Feed it your entire document package
Novek is built for the messy reality of engineering projects — mixed formats, vendor templates, scanned drawings, and project-specific conventions. Upload what you have, define how you want it processed.
P&ID Drawings
Upload scanned or digital P&ID drawings. Novek uses visual AI to read symbols, tags, line numbers, and instrument connections directly from the diagram.
Datasheets
Process equipment datasheets, instrument data sheets, and vendor-supplied technical specs. Extract structured field data across hundreds of pages automatically.
Custom Instructions
Define extraction rules, naming conventions, and validation logic in plain language. Tell Novek exactly how to interpret your project's standards and terminology.
Standards & Specifications
Upload project specifications, codes of practice, and engineering standards. Novek uses them as context to validate extracted data against project requirements.
Vendor Document Packages
Ingest complete vendor document packages with mixed formats. Novek normalizes data across different vendor templates into a consistent project output.
Existing Deliverable Templates
Upload your existing line list or taglist Excel templates. Novek populates them directly, preserving your project's column structure and formatting conventions.
Custom Instructions Engine
Every project has its own naming conventions, tag formats, and validation rules. Write plain-language instructions — "always use the instrument tag in the format {P-####}", "flag any line without a pipe spec assigned" — and Novek applies them consistently across every document in the package.
Example instruction
Flag if missing: pipe class
Cross-check: P&ID vs datasheet
Output: project_linelist.xlsx
Agentic Extraction Engine
AI that reads engineering documents like an engineer
Not generic AI. Not OCR plus pattern matching. A purpose-built extraction engine trained to understand the structure, symbology, and conventions of engineering documentation.
Extraction pipeline
Visual AI for P&ID Drawings
Novek's vision models read P&ID drawings the way a trained engineer would — identifying instrument symbols, tag labels, line numbers, connections, and process flows without needing clean vector data.
Works on scanned PDFs, TIFFs, low-quality blueprints, and legacy CAD.
Topology & Connectivity Modeling
The extraction engine doesn't just read text — it traces lines from nozzle to nozzle, identifying upstream/downstream relationships, inline components, flow direction arrows, and branch reducers.
Builds a complete, queryable process flow graph.
Instrument Loops & Control Logic
Detects primary sensors, transmitters, signal lines (pneumatic, electrical, software), controllers, and final control elements, grouping them into functional control and safety loops.
Preserves DCS/PLC tags and interlock associations.
Cross-Drawing Continuation (OPCs)
Automatically matches off-page connectors across drawing sheets, maintaining process line continuity across an entire plant unit or facility.
Resolves cross-sheet line continuity automatically.
Multi-Outcome Generator
From one unified engineering model, generate DEXPI XML, SmartPlant P&ID imports, verified tabular line lists, equipment registers, and AI context embeddings.
One model serves CAD, EPC deliverables, and AI agents.
Confidence Scoring & Source Anchoring
Every extracted tag, connection, and attribute retains its exact pixel coordinates on the source drawing with a statistical confidence score.
100% auditable down to the drawing pixel.

Human-in-the-Loop Review
The review layer that makes 100% accuracy achievable
AI alone can't guarantee 100% accuracy on complex technical drawings. Novek's HITL layer is designed to make human review so fast and precise that catching and correcting every edge case becomes practical — not theoretical.

Extracted Data
Source Overlay View
Every AI-extracted component is localized back to its exact location on the original drawing. Click any row in your line list and the system jumps to the precise region of the P&ID where that data was found — with a visual overlay highlighting the source.
No more hunting through 50-page P&ID packages to verify a single tag number.
Why HITL changes everything
Pure AI extraction can get you to 90–95% accuracy on complex drawings. The last 5–10% requires human judgment. Without a proper review interface, that last mile takes as long as doing everything manually. Novek's HITL layer collapses that time.

Can't tell where the AI got a value from
Every value traced to its exact source location
Manual checking takes as long as extraction
Review focuses only on flagged low-confidence items

Downstream Model Outputs
Derived deliverables, powered by the connected model
Because Novek builds a true engineering graph, project registers and line lists are not isolated OCR scrapes — they are deterministic, fully verified views of the connected plant model.

Privacy and control
Built for secure, high-stakes engineering environments
Speed alone is not enough. Engineering teams need reviewability, controlled access, deployment flexibility, and confidence in how technical data is handled.
Why it matters
Novek is designed so document automation fits real enterprise and project conditions, not just ideal demo scenarios.
Enterprise-ready privacy
Built for teams handling proprietary technical documentation, sensitive client files, and delivery environments where data control matters.
Role-based access and control
Support controlled access to project data, workflows, and outputs so only the right users can review or export information.
Flexible deployment options
Cloud, private, or controlled environments can be aligned to client and project requirements where deployment boundaries matter.
Audit-friendly review
Traceable outputs help support internal QA, engineering review, and client-facing validation with clearer evidence.
Novek vs manual process
