Frequently asked questions
What is the character limit for Twitter/X?
Twitter/X allows 280 characters per post. Some accounts (verified/premium) have a 4,000 or 25,000 character limit, but 280 remains the standard for maximum reach.
How does the thread splitter work?
The tool breaks your long text into multiple posts, each under the character limit, and numbers them automatically (1/, 2/, 3/, etc.) for easy copying.
Can I customize the numbering format?
Yes. You can choose between "1/5" style numbering, "Thread 🧵" headers, or plain splits without numbering.
Is my text uploaded to a server?
No. The splitting happens entirely in your browser. Your drafts, announcements, and content never leave your device.
