About Listen Notes
Listen Notes is a comprehensive podcast search engine and database that indexes over 3.2 million podcasts and 195 million episodes as of late 2025. Positioned as the 'Google for Podcasts,' its technical architecture focuses on high-performance indexing of RSS feeds, extracting deep metadata including show notes, transcripts, and speaker profiles. For 2026, the platform has solidified its role as the primary data provider for AI agents and LLM developers who require clean, structured audio data for training or context-retrieval (RAG). Its proprietary Listen Score provides a logarithmic scale for podcast popularity, enabling market researchers and advertisers to quantify reach. The platform operates a high-availability REST API that supports complex Boolean searches, filtering by genre, language, and region. It differentiates itself through its 'Listen Real-Time' feature, which monitors global feeds with sub-hour latency, making it indispensable for brand PR and crisis management. By providing structured JSON outputs for traditionally opaque audio content, Listen Notes serves as the bridge between the fragmented RSS world and the modern data-driven enterprise.
