Write it once.
Land it twice.
One box, two timelines. Post to Bluesky straight from here, and open X with the same words ready to send. Nothing is stored on a server — there isn't one.

Bluesky not connected
Use an app password, not your real one. It stays in this tab's memory and goes only to bsky.social.
X opens the composer
X charges developers for posting, so we hand the text to X's own composer — one tap to send.
Free try: 3 posts. Then long posts, split cleanly
Over the limit? Twinpost cuts at sentence breaks, numbers the parts (1/3), and sends a proper reply-chain to Bluesky and one-tap composers for X.
