Yesper is the AI civil engineer for construction and infrastructure. Construction and infrastructure teams lose enormous time to manual, document-heavy work — reading tenders, taking off quantities, checking deliverables against the rules. Yesper's AI agents read a project's documents, drawings and models, reason against the Swedish standards, regulations and contracts a project runs on (AMA, AB 04, PBL, Miljöbalken and more), and deliver whole pieces of engineering work: tender review, quantity takeoff from BIM/IFC and drawings, and compliance checks — each with page-level source citations. It integrates live Swedish authority data (Trafikverket, SGU, SMHI, Lantmäteriet), computes in code so the numbers hold, and stores data in the EU.
