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.
