Our mission
Nobody should lose the chance to say one more thing
ECHO 回响 exists so a voice, a face, and a way of speaking don't have to disappear completely. We help people build a persona from what someone left behind — photos, messages, recordings — and keep a conversation open.
Handled responsibly
A likeness deserves real care
Photos, voice, and video are about as personal as data gets. Here's how we think about handling it.
You control what's uploaded
Every photo, recording, and message is added deliberately, asset by asset, and can be removed at any time.
Likenesses stay private by default
Personas are visible only to the account that created them — never public, never used to train models for other users.
Deletion means deletion
Removing a persona removes its underlying media and derived data, not just the chat interface.
Sensitive by design
Faces, voices, and video are handled as sensitive personal data throughout the product, not just in the fine print.
