What is Onyx?

Onyx is the AI platform for your organization. It connects to your team’s applications, indexes their knowledge, and makes it available to your team and their AI Agents. Onyx gives you reliable answers from your own data and keeps that data private. Search your documents, build custom AI Agents, research the web, run code, and more - all in one place.
