Armature

Armature is analytics for products people reach through an AI client rather than through your own interface. When someone uses your Claude Connector, ChatGPT App or MCP server, the session happens inside their agent, so what lands on your side is a scatter of tool call logs. Armature reassembles those into a session showing the user's intent, the agent's reasoning and the outcome, then scores whether the task actually succeeded.

Its models read every session and group them into use cases ranked by volume and success rate, including the things users kept asking for that you do not support yet. The top workflows become evals you can run before shipping, so a regression turns up before a customer finds it. The free tier covers 1,000 credits a month.
