Boundary-aware splitting
Paragraphs and sentences stay intact where possible, with words used as the final safe boundary.
X and Twitter Thread Composer and Splitter
Turn longer writing into a sequence of standard X posts, then edit, reorder and copy each part of the thread.
- Smart splitting
- X-compatible counting
- Private browser processing
Build your thread
Paste the complete draft once. The splitter preserves natural reading breaks while enforcing the standard weighted limit for every post.
A practical thread workflow
The generated sequence is a starting point, not a locked result.
Optional numbering
Add familiar 1/5-style suffixes with their weighted character cost reserved automatically.
Editable sequence
Refine, reorder, add and remove posts while seeing an exact weighted count for every entry.
Private preparation
Your source text and generated thread remain in the browser and are never posted automatically.
Review before posting
X Utils prepares the text but never signs in or publishes on your behalf.
Copy posts individually when assembling the thread in X, or copy the entire sequence for another writing workflow. Always review mentions, links and transitions in the official composer before selecting Post all.
