One API to query, transcribe, and monitor any public audio in real time — ranked, timestamped, and speaker-attributed results built for LLMs and AI agents.
Describe what you're looking for — a topic, event, or speaker. Sonar understands meaning, not just keywords.
Our real-time index covers podcasts, public radio, congressional hearings, and live broadcasts — all semantically indexed.
Every result returns a score, speaker ID, timestamp, and transcript excerpt — ready to feed directly into your LLM pipeline.
Retrieve mode returns ranked, timestamped clips from the index — fast semantic search with speaker attribution.
