Voker

Voker is an analytics platform for AI agents. It instruments the LLM calls an agent makes, then turns sessions into measurements of how the agent performs, what users are asking for, where it fails, and what it costs. Setup is done with an SDK that wraps existing provider clients. JavaScript and TypeScript support covers OpenAI, Anthropic, Gemini and the Vercel AI SDK, and Python support covers OpenAI, Anthropic and Gemini. Each call is tagged with an agent name and a session identifier. A REST API covers other languages and frameworks. The site also offers a prompt that a developer can paste into an AI coding tool to scaffold the integration. Voker reports on agent cost and return on investment, builds behavioral profiles of users, and surfaces failures and churn signals that would otherwise stay hidden in traces. A feature called Smart Skills generates versioned instructions from user corrections, frustration and failed outcomes, tracks how each one performs, and flags weak ones for automatic optimization. Skills can be applied globally, per company or per user. The product is positioned for leadership, product, engineering and data science groups running production agents. Published plans are Agent Ready at $0 per month, Agent Enabled at $80 per month, Agent First at $400 per month, and a custom Enterprise tier. The free plan includes unlimited seats.
