Deepmarks Deepmarks is a Nostr-native bookmarking app for saving, tagging, importing, exporting, and sharing links on open relays. Public bookmarks are signed Nostr events, private bookmarks are encrypted, and lifetime members can queue long-tail page archives. The mobile app can also act as a Nostr signer. It supports NIP-46 remote signer pairing links and Android NIP-55 signer intents so users can keep their key on their phone while signing into compatible Nostr apps.
