Thread splitter for X (Twitter)

Paste long text and get posts of 280 characters or less, split at sentence ends, never in the middle of a word. Optional numbering, one click to copy each post.

  • Free, no account
  • Everything runs in your browser: your text is never sent anywhere.

    How it works

    • Text is split at sentence ends and paragraphs first, then between two words when a single sentence is over the limit.
    • Each post is counted the way X counts: links as 23, emoji as 2.
    • Numbering (“1/5”) counts toward the 280 characters.
    • It’s the same splitting as “Split into thread” in Hypepen’s editor.

    For a thread people finish

    • The first post has to stand on its own: it’s the one that travels in “For you”, the rest is read when someone opens the thread.
    • One idea per post, in the order a reader needs it.
    • Past 7 posts, few people read to the end: with a subscription, consider a long post or an Article.

    And in Hypepen

    In Hypepen, a post that’s too long for your account offers “Split into thread” with the same preview, and the thread is scheduled like any post.

    Frequently asked questions

    No. It splits at sentence ends, then between words. Only a single word (or link) longer than the limit on its own would stay too long: it would then sit alone in its post.

    It’s optional. Numbering helps people follow a long thread and shows its size; without it, each post keeps more room for text.

    X sets no useful rule here. To get read, keep it short: 3 to 7 posts, with a first post that makes people want the rest.

    No. Splitting happens in your browser, with no network call.
