About
Listen Notes is a comprehensive podcast search engine and database platform that enables users to search, discover, and interact with over 3.7 million podcasts and 188 million episodes. Unlike competing platforms, Listen Notes maintains data integrity by filtering out deleted, low-quality, or AI-generated content through 24/7 automated scripts and human moderation.

Playlists sync to favorite podcast players via RSS. For developers and businesses, Listen Notes provides the Podcast API to build podcast-powered applications, batch-exportable podcast datasets, and a premium membership tier unlocking advanced search capabilities. The platform also offers podcast transcription and summarization services through Listen411.com, capable of transcribing an hour of audio in under a minute on a pay-as-you-go basis. For podcasters, Listen Notes supports podcast submission, integrations to distribute content broadly, podcaster interviews, and even free self-hosted podcast hosting via Cloudflare. The platform supports over 30 languages and is trusted by journalists for research, students for learning, podcasters for cross-promotion, and developers for building next-generation podcast applications.
