Chunks
How to use Token Splitter
- Paste your text.
- Set the maximum tokens per chunk and the overlap.
- Copy individual chunks or download them all as JSON or text.
Formula & assumptions
- Counts are estimates: the tokenizer approximation was calibrated against OpenAI’s o200k_base (typically within a few percent for English prose and code; up to about 20% off for some other languages). Nothing you paste leaves your browser.
- Chunks break at paragraph, sentence or word boundaries, never in the middle of a word.
