Captain is a Y Combinator backed startup (W26) that provides an automated Retrieval Augmented Generation (RAG) service for files. It indexes unstructured data from various sources—including video, documents, images, audio, and handwriting—and enables search via a REST API. The platform claims 95% accuracy on needle in a haystack retrieval tasks, compared to 78% for manual RAG pipelines. Captain handles file processing (OCR, VLM, embeddings), storage, and hybrid search (keyword + semantic) out of the box. It integrates with cloud storage services like Azure Blob, GCP Storage, Amazon S3, SharePoint, Google Drive, Dropbox, Confluence, Slack, Gmail, and Notion.
