What Captain does
Captain provides API-based knowledge search built to give AI agents accurate retrieval across many file types. It indexes and queries videos, documents, images, and audio, handling the full retrieval-augmented generation (RAG) pipeline so teams do not have to set up vector databases or preprocessing infrastructure themselves.
Key capabilities
Captain offers multimodal indexing with automatic OCR and vision language models, plus hybrid search that combines keyword and semantic matching. It integrates with major storage sources including S3, Azure Blob, Google Cloud, SharePoint, Google Drive, and Dropbox, and supports role-based access control with granular metadata filtering. The company reports SOC 2 Type II certification and offers tiered pricing from a free tier through startup and enterprise plans.
Who it's for
The AI infrastructure platform is aimed at developers and enterprises building agents and context-aware applications that need reliable retrieval across diverse file formats, without building and operating their own RAG stack.
