An open source Answer Engine Optimization and Generative Engine Optimization platform that tracks how ChatGPT, Claude, Perplexity, Gemini, Copilot, Grok and Google AI Overviews mention and cite a brand. It measures visibility per tracked prompt and per engine, benchmarks competitors, uncovers citation gaps and produces shareable reports that stakeholders can open without an account. Every metric is auditable in code and calculated by a documented method, and a live demo shows how prompts and citations are analyzed. It is presented as a free alternative to closed tools such as Profound and Peec. Developers get a REST API with TypeScript and Python SDKs and an MCP server for Claude Code, Cursor and Codex. Agencies can track every client brand in one place and use a white-label deployment with custom branding, a custom domain and SSO. MIT licensed, self-hostable, TypeScript.
