Needle-Sharp Answers
The Doublecheck engine combines agentic reasoning with hybrid retrieval to answer complex questions about your construction documents—with citations you can verify.
The Query Pipeline
Every question flows through an intelligent pipeline: from submission to agentic search, through reasoning and citation extraction, to a verified answer with source highlights.
Async Pipeline Injection
Queries enter a distributed task queue, immediately spawning parallel workers. Non-blocking architecture ensures zero wait time while orchestration engines coordinate the multi-stage reasoning pipeline.
Dynamic Retrieval Engine
Multiple search strategies work in concert, dynamically regenerating queries based on initial results. The system iteratively refines its approach—narrowing, expanding, or pivoting—until it finds optimal context.
