What it is

Cue is a Flutter app that turns static content into live, two-way conversations with AI personas. Each persona has its own role, personality, knowledge base, language and voice. It can appear as a real-time video avatar (RunwayML) or as a voice-and-chat agent (OpenAI LLM + STT/TTS).

Natural-language Q&A
Users ask questions by speaking or typing; no menus or forms.
Multimodal pipeline
STT → LLM → TTS, plus a live video avatar over WebRTC.
Knowledge-grounded agents
Persona, instructions and knowledge base go into every reply.
Guided experience
Conversation starters, hints and translation within a set number of turns.
Built-in controls
Google / Apple sign-in, role-based session limits, progress and score tracking.
