About

nostrX automatically publishes your Twitter/X posts to Nostr, letting you reach both audiences without manual cross-posting.

HOW IT WORKS

- When you publish a new tweet, nostrX detects it and posts the same text as a Nostr note
- Sign using a private key or a NIP-07 extension (nos2x, Alby)
- Posts are sent to multiple public Nostr relays for redundancy

FEATURES

- Posts only new tweets (replies are excluded)
- Auto-post toggle to switch between automatic and manual posting
- Manual Nostr button on each tweet
- NIP-07 support, no private key required
- Secure local storage: keys never leave your browser
- Multiple relay support for better reach across the Nostr network

PRIVACY & SECURITY

- Private keys are stored locally using Chrome extension storage
- No analytics, no tracking, no external servers
- Only signed Nostr events are published to public relays

Ideal for users who want a consistent presence on both Twitter/X and Nostr, without the friction of manual cross-posting.
