Support that respects uncertainty.
Emotional Friend offers registered conversations and a temporary guest demo for talking through what is on your mind. Clear boundaries make it explicit that the product is not therapy, diagnosis, crisis monitoring, or emergency care.
Optional expression context runs in the browser after explicit consent. The app shares only a coarse, time-bounded label with the assistant when the user enables tone adaptation—never video frames, landmarks, embeddings, or biometric templates.
Guest conversations remain in versioned local storage and expire after 30 minutes of inactivity. Registered chats are owner-scoped, and the interface supports multiple chats, message recovery, renaming, and clear deletion flows.
Supported Emotions
Advanced AI technology.
A carefully bounded AI system with explicit consent, safety routing, and recoverable states.
Emotion Recognition
A lazy-loaded browser model estimates one of seven normalized expression labels after consent. Every estimate is presented as a guess, never a fact.
Conversational Support
Server-side prompt construction sends bounded, authorized context to the OpenAI Responses API with timeouts, idempotency, and reviewed safety routing.
Resilient Messaging
Optimistic messages reconcile through stable request IDs, retries never send the same message twice, and failed replies keep the user’s original text intact.
Privacy by design.
Built with user privacy as the foundation. All emotion detection is optional.
Camera frames, landmarks, embeddings, and biometric templates stay on the device and are never persisted. Chatting works the same way with expression context switched off.
Registered data is scoped to the signed-in user in Firebase, while guest chat text remains local. Server logs exclude complete conversation text and sensitive identity by default.
