# Civils.ai

> Civils.ai is an AI platform for civil and geotechnical engineering and construction teams — it measures quantity takeoffs from PDF drawings, extracts subsurface/geotechnical data, and runs automated checks across drawings, specs and contracts, with human QA and full auditability.

Civils.ai helps estimators, contractors, consultants and pre-construction teams cut manual document work without cutting corners. Takeoffs are reviewed and verified by an expert QA team; customer data and IP are never used to train models. Used by teams at 200+ firms across 8 countries. Pricing starts at US$90/month.

## Core products & use cases
