Vagent provides a voice-first chat interface for custom AI agents, enabling natural spoken interactions instead of typing, particularly on mobile devices. It connects to backends using a single webhook (secured by authentication) and integrates OpenAI Speech for high-quality, natural-sounding voice input and output. Vagent emphasizes privacy (no registration, data stored on-device), session-based chat history tied to session IDs, and offers templates and documentation (including an n8n workflow template) to build multi-agent setups where a main agent can call sub-agents as tools. Actions are presented as drafts for user confirmation before execution.
