About

Built by architects and engineers, backed by Oxford AI research.

Half practice, half research: our team combines ex-practitioners from architecture and engineering firms with research published at ICML and NeurIPS in computer vision, AI agents, and complex document retrieval. The agent logic is written by people who have done these reviews themselves, not AI generalists.

Built for every role on the project

Architects

Stage 4. 500 pages. Fire strategy, waterproofing, accessibility reviewed against the fire report, sheet by sheet.

Structured checks the same package in 20 minutes and returns every compliance check with the exact page and a recommended fix.

MEP Engineers

Coordinating mechanical, electrical, and plumbing in 2D means tracking conflicts across dozens of sheets without a model.

Structured flags every coordination conflict before the set leaves the office: above-ceiling clashes, penetrations through fire-rated assemblies, equipment missing on plans.

Structural & Civil Engineers

Member tags, penetrations, and setout checked by hand against architectural and services sheets that change with every revision.

Structured cross-checks structural and civil sheets against the full set: tags against schedules, penetrations against structure, levels against grading.

General Contractors

Coordination failures missed in the office become RFIs in the field. At 9.9 per million of contract value, they become the cost structure.

Structured reviews drawing sets at preconstruction and surfaces scope gaps and coordination failures before mobilisation.
