Long text in. A thread out.

It splits long text into a thread of X posts at the ends of sentences, keeps every post within 280 characters as X counts them, and draws each post exactly as X shows it. Copy the posts into X one by one, or schedule the thread with Flaghand.

Each post holds 280. A link counts as 23 whatever its length, an emoji as 2, and each Chinese, Japanese or Korean character as 2. The count here follows X’s composer rule for rule, so a post that fits here fits on X.

At the end of a paragraph or a sentence. Only a sentence too long for one post breaks at a comma, then between words. A link is never cut.

Yes. Under a post, the up arrow moves its last sentence to the next post and the down arrow brings the next sentence up. A line with only --- forces a split there.

In X’s composer, paste post 1, press + to add a post and paste post 2, and so on, then Post all. Or schedule the whole thread with Flaghand.
