Tweet splitter
0 characters in → 0 posts out
Want it rewritten, not just cut? AI turns your article or transcript into a thread with a hook and a closing post, keeping your facts.
Your numbered posts will appear here, stitched in order.
How auto-split chooses the cut
A dumb splitter counts to 280 and chops. That leaves posts ending in “the” and sentences stranded across two posts. This one works like an editor, looking for the most natural break that fits:
- Paragraphs. If a paragraph fits, it stays whole, and small paragraphs are packed together.
- Sentences. A long paragraph is cut after a full stop, question mark or exclamation mark.
- Clauses. A sentence longer than a post is cut after a comma, semicolon, colon or dash.
- Words. Only then does it break between words, and it never splits a word unless one word is longer than a post.
It counts characters the way X does (links 23, emoji 2) and reserves room for the “7/12” label. Drag the slider to watch the seams move.
Splitting is step one. A thread still needs a hook: see hook examples, or run the result through the thread maker’s engagement score.
Where the seams go
- 1Most threads fail in the first post. · 36
- 2People scroll past a vague opener in under a second, so the hook has to promise something specific: a result, a number, a mistake to avoid. · 139
- 3The rest of the thread only matters if post one earns the tap, which is why good writers spend half their time on it. · 117
The paragraph is too long, so it’s cut only between sentences. Every post reads as a complete thought.
Questions
How do I split text into tweets?
Paste your text into the box. The splitter instantly breaks it into posts of up to 280 characters, keeping paragraphs together when they fit and otherwise breaking between sentences. Copy each post, or open the result in the thread maker to edit it.
Will it cut words or sentences in half?
Only as a last resort. It tries paragraph breaks first, then sentence ends, then commas, colons and dashes, then spaces between words. A word is only cut if a single word is longer than a whole post.
Does the numbering count toward 280?
Yes, and the splitter accounts for it. When numbering is on, it reserves room for labels like “12/12” so every numbered post still fits.
Can I put the number at the start instead of the end?
Yes. Choose “1/ at the start” to begin each post with 1/, 2/ and so on, “(1/5) inline” to add it after the last word, or “1/5 at the end” to put it on its own line. The splitter reserves room for whichever style you pick.
Is my text uploaded anywhere?
Not for splitting: that happens entirely in your browser. Only if you press “Rewrite as a thread with AI” is the text sent to the AI model to write the thread, and it isn’t stored.
Can it turn a blog post or video transcript into a thread?
Yes. Paste the article or transcript and press “Rewrite as a thread with AI”. Instead of just cutting the text, the AI writes a hook, one idea per post and a closing post, keeping your facts and numbers. Always check the result before posting.
Can I split for a shorter limit, like Bluesky or Threads?
Yes. Change the post size: Bluesky allows 300 characters and Threads allows 500, though they count characters slightly differently from X.
