Perplexity has launched Sonar, an API service enabling developers to integrate its generative AI search tools into their applications. The API offers two tiers: a basic version for faster, cheaper access, and a Pro version for complex queries with detailed answers. Already adopted by Zoom for real-time AI assistance, Sonar enhances user experience by providing citations without leaving the chat interface. With pricing structured for both versions, Perplexity aims to capitalize on the growing demand for affordable AI tools while increasing its revenue stream following a recent $73.6 million funding round.
