X thread splitter and character counter
Paste your text to see a live character count for X, and split anything too long into a thread that breaks at sentence ends. It does not write replies. It is free, runs in your browser, uses no AI and sends nothing anywhere. For a post or thread drafted in your own voice, use the composer in Reply Monk, which has an X thread builder.

0 / 280
Each link counts as 23 characters. Everything stays in your browser.
Start typing to see your count and, if needed, a thread.
How to use it
- Paste or type your text. The counter updates as you go, with each link counted as 23 characters.
- If it is over 280, the splitter breaks it into posts at sentence ends. Choose whether to number them.
- Copy each post in order, or copy the whole thread.
Tips
- Make the first post stand alone. Many people will only see that one.
- Keep one idea per post. If a post feels crowded, split it again.
- Put the link in the last post, or in a reply, rather than the first.
- Numbering helps long threads. Short ones often read better without it.
Questions
Good to know
How does X count characters?
Most characters count as one, and every link counts as 23 no matter how long it is. This counter does that. Some characters, such as many emoji and Chinese, Japanese and Korean text, count as two on X, and this simple counter does not model those.
Where does it split?
At the end of sentences whenever it can, so posts read as whole thoughts. If a single sentence is longer than one post, it breaks at a word.
Does my text leave my browser?
No. The counting and splitting run in your browser, and nothing is sent anywhere.
Can Reply Monk write the thread for me?
Yes, inside the app. The composer has an X thread builder that works in your voice and shows a live X preview. This free tool only counts and splits text you have already written.
