AnythingLLM

An all-in-one, open-source AI application for Retrieval-Augmented Generation (RAG), enabling users to securely chat with their private documents using any LLM.

AnythingLLM is the complete AI application for document-based chat and RAG, built by Mintplex Labs, Inc. (Y Combinator S22). It allows users to upload diverse content (PDFs, CSVs, codebases) and create 'workspaces' for contextualized conversations, ensuring responses are grounded in the private data. The platform offers two primary deployment models: a privacy-focused Desktop application for local, no-setup use, and a Cloud/Self-hosted option for multi-user teams requiring full tenant isolation and fine-grained admin controls. As an MIT-licensed, open-source solution, it supports a wide range of local and enterprise LLM providers (e.g., OpenAI, Azure) and vector databases (e.g., Chroma, LanceDB).
