How does the Twitter Thread Splitter work?

Paste your long text, and the tool splits it into tweet-sized parts of up to 280 characters. It prefers to split on sentence boundaries so your posts stay readable, and it numbers every part.

What is the character limit per thread part?

The default limit is 280 characters per part, which matches the X (Twitter) post limit. You can lower it if you want shorter posts.

What does the word-boundary option do?

When enabled, the tool never cuts a word in half. If a chunk would end mid-word, it moves the cut back to the last space, so every part ends cleanly.

Can I copy each part separately?

Yes. Every thread part has its own copy button, and there is also a Copy All button that copies the whole numbered thread at once.

Is this thread splitter free?

Yes, it is free, runs fully in your browser, and needs no signup.
