Count characters and split X/Twitter threads
Twitter Tools counts your post's characters against the 280-character limit, and automatically splits longer text into a clean, numbered thread.
Why use this tool
Live character count
See your remaining character count update as you type, with a clear warning once you go over.
Automatic thread splitting
Long posts are split at word boundaries — never mid-word — and numbered like (1/5), (2/5).
Per-tweet copy
Copy each part of your thread individually, ready to paste into X.
Private by design
Your draft never leaves your browser.
How it works
- 1Paste or write your post in the text box.
- 2Watch the character count — if it goes over 280, a thread is generated automatically.
- 3Copy each part and post them in order.
