So we built GUPT. Two dudes, tired of messy Nostr clients.
Not another feed. Just the features:
- Temporary accounts, or permanent ones from memory anchors — choose your style
- Encrypted chat, voice notes, files
- Voice / video calls + screen share
- Encrypted passwords, notes, bookmarks
- transfersh style encrypted share

- PWA everywhere. Flatpak on Linux.
No Nostr bloat. Non-profit. Open source.
