Tweet & thread splitter — turn a long draft into a clean thread

Paste a long piece of text and get an ordered, numbered X/Twitter thread where every tweet fits inside the 280-character limit and no word is ever cut in half. Free, no sign-up, and your text never leaves your browser.

0 tweets

Each tweet is kept within 280 characters, numbering included.

Your thread will appear here, one card per tweet, as soon as you paste some text.

How it works

Paste your long text

Drop your draft, article or long post into the box. It can be as long as you like — paragraphs and line breaks are kept where they fit.

We split it into tweets

Your text is broken on paragraph, sentence and word boundaries so every tweet stays under 280 characters and no word is ever cut mid-way.

Copy and post the thread

Copy each tweet one by one, or copy the whole thread at once. Optional (i/n) numbering makes the order obvious to your readers.

Pro tips

  • Front-load the hook in tweet 1 — it is the only one most people see before deciding whether to keep reading.
  • Keep each tweet a single complete thought; a tweet that stands on its own gets quoted and reshared far more often.
  • Numbering like (1/7) tells readers how much is left and makes the thread feel structured and worth finishing.
  • Aim for around 270 characters per tweet rather than a hard 280 — it leaves room for a last-minute edit or an @mention.
  • End the thread with a clear call to action: a follow, a link, or a question that invites replies.

FAQ

This tool packs each tweet to 280 characters, the standard limit for X/Twitter accounts. X Premium allows much longer posts, but 280 keeps your thread readable everywhere — in quote tweets, embeds and third-party apps — so it is the safe default for a thread meant to be read by everyone.
No. The splitter breaks your text on paragraph, sentence and word boundaries, so a word is never severed across two tweets. The only exception is a single token longer than the limit itself — like a very long URL — which is hard-split as a last resort so nothing is lost.
Yes, optionally. Turn on numbering and each tweet gets an (i/n) suffix — like (1/5), (2/5) — and the tool reserves room for it so tweets never spill over 280 characters once the suffix is added.
Completely. The whole thing runs in your browser: your text is never uploaded, never stored, and never leaves your device. Close the tab and it is gone.
Yes — the word-safe splitting works for any platform. Just note the limits differ: Threads and Bluesky both allow around 500 characters per post, so you can raise the limit there for fewer, longer posts. Once your thread is ready, Keryo schedules and publishes threads across X, Threads, Bluesky and more from one place.
