The Meetra AI Conversation Intelligence API is a modular solution that provides a comprehensive analysis of human conversation audio. This analysis includes transcripts, group dynamics, topic-oriented dynamics and communication patterns throughout the conversation. The modular design allows developers to create complete products and solutions on top of the API. \ \ The infrastructure has been built together by the founders of [Timeqube](https://timeqube.com) and [UMCS University](https://analytics.umcs.pl/) in Poland. ## The Four Layers Meetra AI Operates in four distinct layers of data analysis 1. **Context Layer** - Transcripts, Summaries, Key Points, Questions 2. **Group Dynamics Layer** - Overall Sentiment, Energy, Interactions, Balance 3. **Fluctuation Layer** - Energy, Sentiment, Interaction and individual emotion changes in time 4. **Topic Overlay** - Topics, Contributors, Sentiment, Energy and Interaction Patterns for discovered topics ## Further Reading [Meetra AI Conversation Intelligence API Building Blocks](/meetra-ai-conversation-intelligence-api-building-blocks.md) [Meetra AI Conversation Intelligence API Reference](/meetra-ai-conversation-intelligence-api-reference.md) [Built with Meetra AI](/built-with-meetra-ai.md) ## Current Development Stage Meetra AI is currently in the beta testing phase, with a [demo](https://docs.meetra.ai/) available for users to upload their meetings and view a sample report visualisation. We have opened the API for developers to tinker with different endpoints for free. You can apply for API access [here](https://0tc6yms7ze7.typeform.com/to/ijR0WJsK?typeform-source=meetra.ai).
