# Captain

> Captain is an enterprise agentic search API that delivers fully-managed RAG pipelines with 95% retrieval accuracy, connecting to cloud storage and file systems in minutes.

Captain is a fully-managed knowledge retrieval engine for enterprises that powers AI agents with high-accuracy search over unstructured data. It replaces manual RAG pipeline construction with a single API call, handling OCR, chunking, embedding, vector storage, and re-ranking automatically. Backed by Y Combinator (W26), Captain improves typical RAG accuracy from ~78% to 95% using advanced NLP, embedding enrichment, and fan-out context windows. It connects to existing cloud storage systems in minutes with no data migration required.

- **Universal Indexing** — *Auto OCR + VLM, file conversions, and best-in-class embeddings handle text, PDFs with tables/images, and code files automatically.*
- **Captain Collections** — *Managed vector storage is built-in, eliminating the need for an external vector database.*
- **Agentic + Hybrid Search** — *Weighted keyword and semantic search with re-ranking and configurable top-k results via a simple REST API.*
- **Cloud Storage Integrations** — *Connect directly to Amazon S3, Google Cloud Storage, Azure Blob, SharePoint, Google Drive, Dropbox, Confluence, Slack, Gmail, and Notion.*
- **Role-Based Governance** — *Attach custom metadata to files at index time and filter queries with granular operators to enforce role-based access across any collection.*
- **SOC 2 Type II Certified** — *Enterprise-grade infrastructure security, independently audited and penetration tested.*
- **Credit-Based Pricing** — *Transparent per-page credit pricing based on document complexity (text, basic, or advanced pages), with overage rates and bulk discounts available.*
- **Captain Datasets** — *Access to a private market dataset (Captain Odyssey) available on Enterprise plans.*
- **Streaming & Re-ranking** — *API supports streaming responses, inference, and re-ranking in a single request for production-ready agentic workflows.*
