Overview
The four ways to use Auron, and how to pick the one that matches where you already work.
Auron runs the same organization, agents, knowledge and signals underneath every surface. Which one you use is a question of where you already work, not a difference in what you get.
The four ways in
The Auron Mobile App is the dedicated app for capturing conversations and acting on signals out in the field. Auron in Claude brings that same intelligence into a Claude conversation you're already having, and Auron in ChatGPT does the same for teams standardized on ChatGPT instead. Headless / Custom UI is Auron with no Auron-built front end at all, for teams building their own interface on its API.
How they connect underneath
The mobile app and the web console talk to Auron's own tRPC API directly. Claude, ChatGPT, and any other MCP-capable client connect through an OAuth2-protected MCP server mounted at /mcp, which exposes the same underlying REST surface as a small set of tools instead of a fixed screen. A custom UI built on the OpenAPI-described REST API is that same surface with no MCP layer in between.
None of these is a reduced version of another. Each is a full way into the same agents, knowledge and signals, chosen by whichever surface fits how your team already works.
