Twitter/X Counter + Thread Splitter

How it works

The splitter analyses your text and chunks it into tweets that each fit Twitter/X's 280-character limit:

• Counts the way Twitter does — every URL is exactly 23 characters because of t.co shortening, no matter how long the URL actually is
• Smart cuts at sentence boundaries (. ! ?) or whitespace — never mid-word and never inside an emoji
• Numbering (1/5, 2/5...) is reserved out of the 280 budget, so no tweet ends up over the limit because of the suffix
• Full Hebrew, complex emoji (family, flags, skin tones) and hashtag support — counted exactly the way Twitter counts

Why you need this

Twitter/X blocks tweets over 280 chars, and even X Premium accounts get more reach when they thread instead of posting one long block. Manual splitting is painful — you count, you cut, you add 1/n suffixes, you discover tweet #1 went 4 over because of the numbering. This tool does it all live, including correct URL handling (Twitter always shortens to 23 chars) and emoji weighting (some look like 4 chars but count as 1).

FAQ

Why is a URL counted as 23 chars even if it's longer?

Twitter automatically shortens every link through its internal t.co service, so any URL counts as roughly 23 characters regardless of its real length. Even a 200-character URL only takes up 23. Our tool applies the exact same weighting Twitter does, so what you see here is what you'll get when you post.

Is my text stored anywhere?

No, zero. The tool runs 100% in your browser — nothing is sent to a server, no cookies, no localStorage. You can verify this in DevTools → Network and see no requests going out.

What's the difference between numbering styles (1/5 vs 🧵 1/5)?

Functionally identical — readers understand both. '1/5' saves 2 characters per tweet, '(1/5)' is slightly more visually clear, and '🧵 1/5' with the thread emoji explicitly signals 'this is a thread' and helps X's algorithm group your posts. We recommend 🧵 for marketing content and 1/5 for dense technical writing.

What about X Premium with 25,000 chars?

X Premium allows much longer single tweets, but 2025 engagement studies show that threaded posts still get 2-3x more interaction because each tweet appears separately in the feed. This tool optimises for the standard 280-char case; if you have Premium, you can simply post the full text as one long tweet directly on X.
