Overview
About this tool
Splits long-form text into numbered posts at paragraph and sentence boundaries — never mid-sentence — and accounts for the characters that numbering itself consumes so the last post does not overflow.
Instructions
How to use it
Paste your text and choose a character limit — 280 for a standard account, up to 25,000 for Premium. Blank lines are treated as deliberate breaks, so structure your draft in paragraphs and the split will follow your intent.
Why this splits better
Naïve splitters cut at exactly 280 characters, which lands mid-sentence and reads badly. This one prefers paragraph breaks, then sentence endings, and only ever cuts inside a sentence when a single sentence genuinely exceeds the limit.
