Does this account for links taking 23 characters on Twitter?

Twitter automatically wraps URLs using t.co, taking 23 characters regardless of URL length. If your tweet contains long URLs, keep your text a few characters under 280 to accommodate t.co shortening.

What is the maximum text size I can paste?

You can paste articles of any length. The tool will cleanly partition essays into 10, 20, or more numbered tweets in milliseconds.

Twitter / X Thread Splitter: the complete guide

A Twitter / X Thread Splitter automatically segments long-form essays, blog articles, and newsletters into individual, numbered tweets adhering to the 280-character limit. Long-form posts are proven to drive outsized reach and engagement on social platforms, but breaking an 800-word essay into numbered tweets manually is time-consuming. This tool analyzes sentence boundaries, splits text naturally without breaking mid-word, adds customizable (1/n) tweet numbers, and provides a 1-click 'Copy All Tweets' workflow.

Smart Tokenization: Preserving Sentence Flow

Naive text splitters cut text strictly at character 280, often splitting words or cutting sentences mid-clause. This tool prioritizes natural paragraph and sentence endings, backtracking to the nearest punctuation mark so each tweet forms a coherent thought.

The Power of Numbered Tweet Threads (1/n)

Adding thread numbering (e.g. ' (1/7)') signals to readers that more valuable content follows below, encouraging them to click through, bookmark, and engage with the entire thread. The splitter calculates total tweets dynamically and reserves character budget for the counter.

Step by step: how to use Thread Splitter

1
Paste your long-form article, draft, or notes into the input box.
2
Verify the tweet length limit (default is 280 characters).
3
Toggle thread numbering on or off according to your posting preference.
4
Review the split tweet cards in the live thread preview.
5
Copy individual tweets or click 'Copy All Tweets' to paste the entire thread into scheduling tools like Typefully, Buffer, or Hypefury.
