Vagent is a conversational interface for custom AI agents, providing users an intuitive channel to interact with their automation workflows. The tool is versatile and can be integrated with any back-end system using a single webhook, making it universal in its application. Vagent enables natural interaction with AI agents, with a particular focus on voice commands, facilitating efficient operation especially on mobile platforms. It leverages OpenAI Speech for high-quality, natural sounding voice interaction, and can automatically detect and support more than 60 languages. Vagent ensures both voice input and output are catered to, with the functionality to have different spoken and written outputs. The tool prioritizes user privacy and doesn't collect personal data. All settings and chat history are stored on the users device. The software also allows users to start new chats with unique session IDs anytime, offering the ability to reset these sessions as needed. The application also supports modularity and abstraction layers by allowing the main agent to call sub-agents as tools. Users can also see actions listed as drafts before execution, enabling them to review and confirm each action.Developers have the flexibility to use existing templates, such as the n8n workflow template to build their own multi-agent system connected to Vagent. However, they are also free to build their own unique back-end systems for Vagent, with detailed documentation provided to help set up the endpoints correctly.
