  3. The text splits instantly — copy individual parts or the entire thread at once.

About this tool

A thread splitter takes a long text and breaks it into parts that fit within a platform's character limit. It tries to split at sentence boundaries so each part reads naturally, and adds part numbers (1/N, 2/N...) for readers to follow.

Twitter/X allows 280 characters per post. Instagram carousel captions can be up to 2,200 characters but are cut off visually after about 125. LinkedIn posts are cut at 3,000 characters. This tool handles any limit you set.

The split is by character count, not by word count. Emojis count as 2 characters on some platforms — the tool counts them as JavaScript characters (which may differ from the platform count by 1 for some emoji).

Frequently asked questions

Does it preserve paragraphs?

It tries to split at paragraph or sentence boundaries. If a single sentence exceeds the limit, it splits mid-sentence.

Does it add thread numbers?

Yes — each part is numbered (1/N, 2/N).

Does my text leave the browser?

No. Everything runs locally in JavaScript on your device — nothing is transmitted or stored.
