FAQ
How does the thread splitter decide where to break?+
It prefers paragraph breaks, then spaces, and never cuts inside a detected http/https URL. Oversized segments are hard-split by weighted length as a last resort.
Are numbering prefixes counted?+
Yes. When numbering is enabled, prefixes like 1/5 are included in the 280 weighted budget so each part pastes cleanly.
Can I copy one tweet at a time?+
Yes. Each part has a copy button, and you can copy the full thread with blank lines between tweets.
