# InvokeRank

> InvokeRank measures which software AI agents actually choose: whether an agent finds, selects, calls and completes a task with a product, and who it chooses instead, with the evidence class, sample and interval behind every number.

Measurement runs through the OpenAI and Anthropic APIs and is labelled as an API approximation of the consumer apps. InvokeRank never automates chatgpt.com or claude.ai and never sees anyone’s ChatGPT or Claude conversations.
