Start typing to see your thread split into posts.

Turning a long piece of writing into a thread means counting characters and cutting sentences by hand, over and over, for every post in the thread. This tool does that arithmetic for you.

Paste your text, pick a platform, and it splits the text into numbered chunks that fit that platform’s character limit, without cutting a word in half. Copy each part individually or copy the whole numbered thread at once.

How it works

  1. 1

    Paste your text

    Drop in the long post or article you want to turn into a thread.

  2. 2

    Pick a platform

    Choose X, Threads, Bluesky, or set a custom character limit.

  3. 3

    Copy the thread

    Copy each numbered chunk on its own, or copy the whole thread at once, ready to post.
