Ironclad has open-sourced Rivet, an IDE for developing AI applications. It is a visual programming environment designed specifically for enterprise development teams and supports extensibility through plugins. AssemblyAI collaborated with the Rivet team to contribute transcription and LeMUR capabilities. The plugin allows users to transcribe audio and apply LLM to their transcripts using LeMUR, which can then be integrated into applications using Node.js. A step-by-step tutorial is provided for building an application that answers questions about podcast episodes using Rivet and Node.js.
