OSIsoft PI System
Alternative: Engineering Data, Not Operational Time-Series
OSIsoft PI is the global standard for operational time-series data: sensors, historians, real-time process data, asset performance management. It is not built for engineering document extraction. Pathnovo extracts structured engineering data from documents (P&IDs, isometrics, datasheets, HAZOP, mill certs) to produce EPC deliverables and feed asset information platforms. Different target data: PI processes operational time-series; Pathnovo processes engineering documents. Complementary, not competing. Most operators run both: PI for operations data, Pathnovo for engineering data.
Why Switch from OSIsoft PI System (AVEVA PI)
Engineering Documents vs Operational Time-Series
OSIsoft PI's strength is operational time-series data: sensor readings, historian data, SCADA streams, real-time process data, asset performance metrics. Pathnovo's strength is engineering documents: P&IDs, isometrics, datasheets, HAZOP studies, mill certificates. Different data sources, different target workflows. PI cannot extract from PDFs; Pathnovo cannot process sensor streams. The two address distinct data layers.
Asset Information for PI Context
PI's tag namespace and asset hierarchy benefit from structured engineering data: equipment metadata, instrument loop relationships, piping line connections, valve specs, P&ID source. Pathnovo extracts that engineering context from documents and feeds it into PI's asset hierarchy, enriching PI tags with the engineering metadata they need for operational decisions.
EPC Project Delivery Pathway
PI is operations-focused, deployed after plant commissioning. Pathnovo is built for EPC project delivery: instrument index, MTO, MR / BOM, compliance registers, ready before commissioning. For greenfield projects, Pathnovo runs during construction + commissioning; PI runs after commissioning. Different points in the asset lifecycle.
Indian Regulatory Layer
PI has no IBR, OISD 118, PESO, or CCOE compliance output. Pathnovo encodes all four Indian regulatory regimes alongside engineering data extraction. For Indian PSU refineries and Gulf NOC projects running PI as the operations historian, Pathnovo provides the compliance layer PI does not address. See the indian EPC compliance bundle.
Mid-EPC Accessibility
OSIsoft PI is enterprise-tier with multi-year licensing (typically $500K+/yr at scale). Pathnovo is credit-based with full platform on every paid tier; mid-EPC contractors can produce engineering deliverables without enterprise PI commitment. The two address different commercial scopes. See pricing for plans.

Pricing Compared
Transparent pricing for every vendor where public. Where the vendor does not publish pricing, we say so.
Pathnovo
Credit-based subscription, full platform on every paid tier (engineering document extraction + EPC deliverables + compliance + procurement). 14-day free trial with 100 credits and no card. Feeds PI asset hierarchy with extracted engineering context from documents; does not replicate PI's operational time-series capture. Published per pricing page.
OSIsoft PI System (AVEVA PI)
Enterprise AVEVA licensing typically $500K+/yr at scale, with multi-year contracts and integration scope (PI Server + PI Vision + PI Asset Framework + PI Integrator add-ons). Used by 95% of Fortune 500 industrial companies (BP, Shell, ExxonMobil, Aramco, Reliance, Dow, BASF, ArcelorMittal). Acquired by AVEVA in 2021 for $5B; now part of AVEVA's broader operations + engineering portfolio. Operations-focused; engineering document extraction outside PI's scope.
Who Wins for Which Buyer
Real buyer scenarios with honest “who fits best” framing.
Tier-1 owner-operator running PI as operations historian + needing engineering data extraction for asset hierarchy enrichment
Winner: Pathnovo + PIComplementary architecture. PI handles operational time-series data capture + APM + predictive maintenance. Pathnovo extracts engineering data from PDFs and feeds PI asset hierarchy with structured engineering context (instrument loops, equipment metadata, P&ID source). Different layers; both required for full asset lifecycle visibility.
Greenfield EPC project pre-commissioning with structured engineering deliverables needed before plant goes operational
Winner: PathnovoPI is operations-focused, deployed post-commissioning when sensor data starts flowing. Pre-commissioning, the workflow is EPC project delivery: instrument index, MTO, MR / BOM, HAZOP register, mill cert traceability, compliance registers. Pathnovo produces all of these from project documents. PI takes over once the plant starts operating.
Brownfield digitisation with decades of legacy PDF engineering drawings + existing PI historian
Winner: Pathnovo + PIPI cannot extract from PDF engineering documents; the brownfield engineering history stays locked in PDFs. Pathnovo extracts that engineering context and backfills PI asset hierarchy with structured data + IBR / OISD / PESO compliance views. Pair Pathnovo upstream (extraction) with PI downstream (operations) for full lifecycle coverage.
Indian PSU refinery with PI historian + IBR + OISD 118 + PESO + CCOE compliance obligations
Winner: Pathnovo + PIPI has no Indian regulatory bundle. Pathnovo encodes all four regimes natively while running alongside PI's operational time-series capture. The compliance views complement PI's operational visibility. See the indian EPC compliance bundle.
Owner-operator with mature AVEVA stack (PI + AIM + Engineering + Connect)
Winner: Pathnovo + AVEVA stackAVEVA-stack optimised pattern. AIM aggregates structured asset data; PI captures operational data; Pathnovo extracts engineering data from non-AVEVA sources (PDFs, scanned, third-party CAD) and feeds AIM, which then feeds PI's asset hierarchy. Pathnovo bridges what AVEVA Engineering cannot ingest natively. See the AVEVA AIM alternative.
When the competitor is still the right choice
Honest framing matters. Here are the scenarios where Pathnovo is not the right fit.
- 01
PI's operational time-series data capture + APM + predictive maintenance + real-time process data are outside Pathnovo's scope. We are engineering document AI, not operations data historian. For operational time-series workflows, PI (or comparable: Cognite, AspenTech IP.21, Honeywell PHD) remains the platform; we feed it.
- 02
PI's 95% Fortune 500 industrial penetration + AVEVA enterprise integration demonstrate the platform-maturity Pathnovo does not replicate. For tier-1 operators with mature AVEVA stacks, PI is the architectural fit for the operations layer.
- 03
PI's deep APM, predictive maintenance, and real-time analytics are materially stronger than any engineering-AI extraction layer for operations-time decision support. Pathnovo addresses the engineering data layer; PI addresses the operations data layer. Different workflows.
- 04
For organisations committed to the full AVEVA stack (PI + AIM + Engineering + Connect) as the corporate operations + engineering backbone, AVEVA's integrated scope is the natural cultural fit. Pathnovo bridges what AVEVA Engineering cannot ingest natively from non-AVEVA sources, but does not replace the AVEVA ecosystem.

Frequently Asked Questions
Is Pathnovo a replacement for OSIsoft PI?
No. PI is an operational data historian: it captures, stores, and analyses time-series sensor and process data from operating plants. Pathnovo is an engineering document AI: it extracts structured data from PDFs and scanned drawings (P&IDs, isometrics, HAZOP, mill certs). Different data sources, different target workflows. Most operators run both: PI for operations data, Pathnovo for engineering data. The two are complementary.
Can Pathnovo feed data into OSIsoft PI?
Yes. Pathnovo extracts structured engineering data (tags, instrument loops, equipment metadata, P&ID source) that enriches PI's asset hierarchy and tag namespace. For greenfield projects, Pathnovo provides the engineering context PI tags need for operational use. For brownfield digitisation, Pathnovo backfills PI asset hierarchy with structured data from legacy PDF drawings.
Should Indian PSU refineries running PI also use Pathnovo?
Yes. PI handles operational time-series data for the commissioned plant. Pathnovo handles engineering document extraction + IBR + OISD 118 + PESO + CCOE compliance, which PI does not address. For Indian PSU refineries (IOCL, BPCL, HPCL, Reliance, MRPL, ONGC), the two layers cover different obligations: PI for operations data, Pathnovo for engineering data + Indian regulatory compliance. See the indian EPC compliance bundle.
What about AVEVA's acquisition of OSIsoft PI?
AVEVA acquired OSIsoft in 2021 for $5B. PI is now part of the AVEVA portfolio alongside AVEVA AIM (asset information management), AVEVA Engineering (authoring), and AVEVA Connect (cloud platform). For operators committed to the full AVEVA stack, AIM + PI together cover engineering data + operations data within one ecosystem. Pathnovo feeds AVEVA AIM with extracted engineering data from non-AVEVA sources; AIM then feeds PI for the operations layer. See the AVEVA AIM alternative.
What is the cost comparison?
OSIsoft PI enterprise licensing is typically $500K+/yr at scale, with multi-year contracts and integration scope. Pathnovo is credit-based, full platform included on every paid tier, with a free 14-day trial. For operators running PI as the operations historian, Pathnovo adds the engineering document AI layer at credit-based pricing without expanding the PI footprint. See pricing for plans.
