Free tools / Thread splitter
Turn release notes into a thread for 饾晱
Paste release notes or any long text. Each blank-line paragraph becomes its own post, and a paragraph too long for one post is cut at sentence ends, then between words, so every post fits 饾晱's limit.

4 posts, each within 280 characters as X counts them.

Rollbacks take one command now: rocket rollback, and the previous deploy is live again. 2/4
Cold starts are faster, because the build cache is kept between deploys. 3/4
Thanks to everyone who reported bugs this month. Keep them coming. 4/4

How it works
To split long text into an 饾晱 thread, keep one idea per post and cut at natural breaks. This splitter starts a new post at every blank line, cuts a paragraph that is too long at the end of a sentence, and only between words when a sentence alone is too long. Links are never cut. With numbering on, each post ends with 1/n, and room for it is kept before cutting, so a numbered post still fits 280 characters as 饾晱 counts them.
Questions
Where does it cut?
At every blank line first. A paragraph longer than one post is cut at sentence ends, and a sentence longer than one post between words. A link is never cut in two.
Does the numbering count toward the limit?
Yes. The splitter keeps room for the 1/n at the end of each post before it cuts, so every numbered post still fits.
Can it post the thread for me?
No. Copy each post into 饾晱 yourself. Nothing here connects to your 饾晱 account.
Is this the splitter Crux uses?
Yes. It is the same code that splits thread drafts in Crux.
From one post to every push
Crux (cruxpost.com) watches the GitHub repos you choose. Each push, merged pull request or release becomes three drafts in your voice, checked the way this site鈥檚 tools check a post, and your coding agent can add why a change matters through the Crux plugin for Claude Code and Codex. Crux reads commit messages, pull request and release text and the names of changed files, never a diff. Post on X copies the draft you like and opens X with it, for you to post; on Autopilot, Crux posts only what you schedule. It reads each post at 1 hour, 24 hours and 7 days, and learns which kinds of post work for your account only once a pattern beats chance.
