I was in Iran 2 years ago. Almost everything was censored.

Tried to message my wife on Primal. Broken.
Amethyst worked — except she has an iPhone. And no voice notes.

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
- ntfy-style alerts to your pubkey
- Telegram-style bots (gupt-sdk) — encrypted DMs, not public Kind-1 spam
- PWA everywhere. Flatpak on Linux.

No Nostr bloat. Non-profit. Open source.
