Stampwise · Quotation agent for pressure vessel fabricators
Stampwise is an AI agent for pressure vessel fabricators. It reads the specifications, data sheets and drawings, lists every requirement with its source, flags the gaps and drafts the quotation workbook your estimator signs off. In daily use on live bids since early 2026.

How it works01 Product
Our first product, Stampwise, is an AI quotation and engineering agent for ASME pressure vessel fabricators. It reads an RFQ package, extracts every requirement line by line, flags gaps and drafts a reviewable quotation workbook. In daily use on live bids at a U stamp fabricator in Korea since early 2026.
Specifications, data sheets, drawings and vendor forms go in. The agent extracts the requirements line by line and keeps a source reference for each one.
Useful for Turning a long RFQ package into a requirement list a reviewer can check in an hour.
Long context · Document extraction
Missing data, conflicting revisions and unusual conditions are flagged before pricing starts, with a draft clarification list for the customer.
Useful for Catching a missing design pressure or an impact test requirement before it costs money.
Agent workflows · Validation rules
The agent drafts the quotation workbook: materials, fabrication, NDE, testing and quantities, each line traceable. The estimator reviews and signs off.
Useful for A consistent first draft on every bid instead of a blank spreadsheet.
Python · Excel · Deterministic pricing gates
A Neo4j ontology links requirements, components, calculations and prices, so any figure in the quotation can be traced back to the clause or drawing it came from.
Useful for Answering where a number came from during customer review.
Neo4j · Ontology · Knowledge graph
Thickness and allowable stress checks run in deterministic code with source approved tables, never inside the language model. The agent prepares the inputs and explains the result.
Useful for Keeping ASME VIII Division 1 and 2 checks repeatable and inspectable.
Python · MCP tools · Source approved tables
Pricing and engineering decisions stay with people. The agent proposes, flags and documents; a named reviewer approves every quotation before it leaves.
Useful for Using AI on bids without giving up control of the final number.
Review gates · Audit trail · Agent SDK
Stampwise runs on Anthropic's Claude models through the Claude API and Agent SDK, with MCP servers connecting it to the ASME engine, pricing data and the Neo4j ontology.
02 How it works
The agent does the reading and the first draft. Your estimator keeps the judgement and the final number.
Specifications, data sheets, drawings and vendor forms, in English, Korean or both. The agent reads the whole package and indexes every clause.
Every requirement comes with the clause it came from. Missing data and conflicts are flagged, with a draft clarification list for the customer.
The workbook arrives with traceable lines and deterministic ASME checks. The estimator reviews, adjusts and signs off before anything is sent.
03 In production
In daily use on live bids at an ASME U stamp pressure vessel fabricator in Korea since early 2026.
Built by an estimator, for estimators. Every quotation still goes out under a person's name.

Quotations and pressure vessel designs are high stakes. The agent is designed so a person can check every number before it leaves.
Requirements and workbook lines link back to the clause or drawing they came from, through a Neo4j ontology.
ASME Section VIII checks run in deterministic software with source approved tables. The language model never invents an allowable stress.
Quantity and total gates run before review, and no price is issued without a named estimator approving it.
Processed through the Claude API under Anthropic's commercial terms, never used by SPS to train models, and deleted after a pilot unless you ask us to keep them.
06 FAQ
More detail in the docs.
Pressure vessel and heat exchanger fabricators, and other plant suppliers who quote against engineering RFQ packages.
PDF, Word and Excel files: specifications, data sheets, material requisitions, vendor forms and drawings in PDF. English, Korean and mixed packages.
No. The model prepares inputs and explains results. Thickness and allowable stress checks run in deterministic code with source approved tables.
Documents are processed through the Claude API under Anthropic's commercial terms. SPS does not use them to train models. See the Privacy Policy.
Six weeks on one product family and up to 20 of your real RFQ packages, with a weekly review and an evaluation report at the end. The fee is credited to year one if you subscribe within 30 days.
Yes, as a custom deployment of the same agent stack, for example RFQ intake or engineering knowledge search. See Pricing.
07 About SPS
Dangjin, Republic of Korea
Seoul Plant Service is a software company building AI agents for the industrial plant supply chain, starting with pressure vessel quotations.
Based in Dangjin, Republic of Korea, SPS was founded in April 2025 by Jun Tea Kim, a quotation engineer who has priced ASME pressure vessels at a U stamp fabricator in Korea. The company builds AI products for the industrial plant supply chain. Its first product, Stampwise, a quotation and engineering agent for pressure vessel fabricators, has been in daily use on live bids since early 2026. The same agent stack is offered to other fabricators and plant suppliers as pilot and team deployments.
