Split long text into token-bounded chunks.

Overview
Splits a long document into chunks that each stay under a token limit — useful for fitting content into a context window or preparing chunks for embeddings, splitting on paragraph boundaries rather than mid-sentence.
How to use it
- 1Paste a long document.
- 2Set the maximum tokens per chunk.
- 3Copy each chunk individually.
Tips
- Splits happen at paragraph breaks, not mid-sentence — a very long single paragraph that exceeds the limit on its own will still form one (over-limit) chunk rather than being cut arbitrarily.
