Vogent
Build AI Voice Agents. Fast.
Vogent is a platform for building, testing, and deploying AI voice agents that handle phone calls. It addresses the work of creating conversational agents that can navigate phone menus, hold natural conversations, reach humans when needed, and act on call outcomes afterward.
The no-code Flow Builder lets users assemble agents from building blocks that ask questions, discuss topics, and call external tools, hosted on phone numbers selected by area code. For developers, Vogent provides APIs and native SDKs covering turn-taking, conference calling, IVR detection, and custom models, including OpenAI-compatible endpoints for bringing your own model. Additional capabilities include call transfers, knowledge bases for real-time document lookup, functions and tools for live API calls, call history with recordings, transcripts and extracted outcomes, counterfactual analysis for evaluating agents against past conversations, and post-call automations that trigger integrations based on parsed outcomes. The platform also offers Voicelab text-to-speech, custom conversational models, and IVR detection and navigation.
Vogent serves both non-technical builders and developers embedding voice functionality into their own applications. A free trial is available, and fine-tuning with solutions engineers is offered on the enterprise plan, which also includes custom-trained agents, dedicated infrastructure, support, and HIPAA-compliant workspaces.
