GoKawiilParticle pivots to podcast search with new AI tool Radar
Particle, the AI newsreader startup started by ex-Twitter engineers, has launched Radar, a search engine that transcribes and semantically indexes over 130,000 podcasts to surface quotes and highlights. The product grew out of a popular clip-sourcing feature in Particle's news app and is now offered as a standalone API for AI agents and data buyers, including hedge funds and search platforms like Exa.
