Agentic AI for construction and infrastructure data
Links documents, registers, drawings and databases by shared anchors such as asset IDs, so information that lives apart is understood together.
Turns an objective into a repeatable grid where rows are sources and columns are prompts, and each cell is a typed answer with a citation.
Findings keep a trace back to their source records, so teams can inspect the issue and trust the answer before acting.
Agreed checks and review steps let teams test the approach, surface disagreements and keep human review in the loop.

Free AI-powered PDF editor, converter and reader for every device
Upload a PDF and ask questions in natural language, follow up on details and see which passages the answers came from. A separate chat mode works with YouTube videos.
