Needle is a knowledge and AI-search platform that uses agentic retrieval-augmented generation (RAG) to let teams ask questions and get grounded answers from their own data. It connects to common enterprise sources such as Confluence, Slack, Gmail, Dropbox, and GitHub, indexes that content, and retrieves the most relevant, current context to feed a language model, so answers are based on the organization's real knowledge rather than a model's general training. Beyond a search interface, Needle exposes an API and tooling for building AI agents on top of a company's knowledge base, positioning itself as a way to add reliable, source-grounded AI answers to internal workflows or products. The agentic RAG approach is meant to improve accuracy and reduce hallucination by grounding responses in retrieved documents and keeping answers tied to sources. Needle is an early-stage company founded in 2024 with a presence in San Francisco and Berlin, aimed at businesses that want to make internal knowledge searchable and usable by AI. It offers a free tier and affordable paid plans, making it accessible to smaller teams while targeting enterprise knowledge-search use cases.
