X Thread Splitter
Paste long-form text and split it into a numbered X thread, breaking at sentence boundaries wherever possible. Switch to LinkedIn mode to check the 3,000-character limit instead.
How it splits: the tool fills each part with whole sentences first, falls back to word boundaries when a sentence is too long, and only hard-breaks if a single word exceeds the limit. Numbering space is reserved before splitting, so every part fits with its prefix included. Counts here are plain character counts; remember X counts every URL as 23 characters and most emoji as 2, so a part packed with links may behave slightly differently when posted. Hook readers in part 1, one idea per part, and put hashtags on the last part so the opener stays clean.
