Text Splitter
Split a long document into numbered parts that each fit a token or character budget, so you can paste it piece by piece into ChatGPT, Claude, or any chat UI with an input limit. Parts break at paragraph and sentence boundaries, never mid-word.
Parts
How it works: tokens are estimated as characters / 3.6, the typical average for English prose, so a 4k-token budget maps to roughly 14,400 characters. The splitter fills each part with whole paragraphs first; a paragraph that is too large is broken at sentence boundaries, and only an enormous single sentence gets a hard character split. When headers are on, room for the "Part i of N" line is reserved inside the budget. Estimates are approximate; leave headroom if your target UI counts tokens exactly.
