Emberclear
End-to-end encrypted multi-device chat built on the Nostr protocol. Messages only decrypt on your device. Open-source, no server-side data, fully auditable. Keys never leave the browser, which means losing the device means losing the history — by design.
Emberclear opens in a browser tab — no download.
Not sure how to add Emberclear to your home screen? Step-by-step for Chrome, Safari, Firefox and Edge — it takes about ten seconds, and there is no app store involved.
