Onyx

Work AI: enterprise search, assistant, and agents over your apps.

A workplace AI platform that unifies search, an assistant, and agents across 100+ connected enterprise apps (Slack, Teams, GitHub, ServiceNow and more). It enforces each user's existing access permissions over the indexed content. Sold enterprise-only — pricing is quote-based via sales, with no public self-serve tier.

All-in-one private AI app for chatting with your documents, with agents.

An all-in-one application for private, ChatGPT-style chat over your own documents, with built-in RAG, AI agents, and multi-user workspaces. Runs as a local desktop app (Mac/Windows/Linux) or self-hosted via Docker, and supports 40+ LLM providers plus local models with your own keys. Open source under MIT; Mintplex Labs also offers a paid hosted instance, making it freemium.

Self-hosted ChatGPT alternative unifying every major AI provider.

A self-hosted AI chat platform that puts many providers behind one ChatGPT-style UI, with agents, code interpreter, web search, image generation, artifacts, file analysis, and multi-user auth. You run it yourself via Docker and supply your own model keys, or point it at a local Ollama/OpenAI-compatible endpoint. The software is MIT-licensed at no cost.

AI second brain that chats with your docs and the web, local or hosted.

An open-source "AI second brain" for chatting with local or online models, searching across your personal documents and the internet, building custom agents, and automating research. Self-host it on your own machine, or use plugins for Obsidian, Emacs, desktop, and mobile. Licensed AGPL-3.0; a paid managed cloud tier also exists, so it's freemium.
