Overview

Symbl.ai provides conversation intelligence APIs for enterprises building real-time AI agents and multimodal experiences. Its APIs analyze voice, video, and chat to extract transcripts, topics, action items, follow-ups, questions, trackers, summaries, sentiment, analytics, and entities. Nebula is Symbl.ai's conversation-focused language model for analyzing and generating conversation-centric text; its page states it 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 apps. 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, with other limits including five concurrent connections. Pay-as-you-go rates are also listed, while Enterprise pricing is custom and includes support, SLAs, and private-environment deployment. Data at rest is encrypted with AES-256 and data in transit with TLS. Conversations and processed intelligence are retained by default; audio recordings and voice streams are not stored.
