About nostrX

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.
