Echo AI is a voice-powered AI assistant — talk to it, and it uses tools and remembers context across sessions. Built on the NextGen platform with Google and email sign-in.
Approach
Built the voice assistant experience on the shared agent + voice runtime.
Tool-calling with persistent, per-user memory.
Passwordless / social login via the auth platform.
Architecture
Voice pipeline + agent runtime with tool use and memory.
Runs on the orchestration layer for provider routing and fallback.
Google + email auth via the identity platform.
