Summary

Symbl.ai provides conversation intelligence for organizations building real-time AI agents and multimodal experiences. Its APIs analyze voice, video, and chat, extracting transcripts, topics, action items, follow-ups, questions, summaries, sentiment, analytics, entities, and trackers. Nebula, its conversation-focused large language model, analyzes and generates conversation-centric text, can process up to 16,000 tokens, and supports English, Spanish, French, German, Italian, and more. SDKs support adding conversation intelligence to web and mobile applications. Integrations span CRM, business intelligence, meeting platforms, and data stores including BigQuery, Google Cloud Storage, Snowflake, AWS S3, AWS Redshift, Databricks, and Microsoft SQL Server. A free plan includes up to 1,000 audio/video minutes and 10,000 text words per month, among other limits; usage-based pricing is also listed.
