About Captain
Captain syncs complex, multimodal files and cloud storage from sources like S3, SharePoint, and Google Drive, and makes that knowledge searchable for your agents. Instead of stitching together parsers, embeddings, vector databases, rerankers, and retrieval infrastructure, Captain self-tunes the retrieval pipeline to your data and workloads. On benchmarks, this improves accuracy from roughly 78% with standard RAG to over 97% by tuning retrieval to the unique structure and content of your data. Captain is purpose-built for complex, regulated, and high-stakes file search workloads. Learn more at https://captain.dev
