Semantic chunker / text splitter / RAG chunker / chunking with overlap / sentence + paragraph aware. Splits long text into chunks with three modes: 'fixed' (hard char-count windows with overlap), 'sentence' (greedy pack of sentences up to chunk_size), 'paragraph' (split on blank lines, never pack across paragraphs). Returns each chunk's text, start/end character offsets, and char count. Pure local — no upstream call.
INPUT — request schema
| property | type | description | req? |
|---|---|---|---|
| text | string | Text to split. Up to 1,000,000 chars. | required |
| chunk_size | number | Target chunk size in characters. Range [50, 20000]. Default 500. | optional |
| overlap | number | Overlap between chunks in characters. Default 50. Capped at chunk_size - 1. | optional |
| mode | string | Splitting strategy. Default 'fixed'. enum: fixed · sentence · paragraph | optional |
OUTPUT — response shape
| field | type | description |
|---|---|---|
| chunks | string | Array of chunk objects, each with text, start offset, end offset, and char count. |
| chunk_count | string | Number of chunks produced from the input text. |
| mode | string | Chunking mode used: 'fixed', 'sentence', or 'paragraph'. |
| chunk_size | string | Target maximum character size per chunk as applied. |
| overlap | string | Character overlap between adjacent chunks (fixed mode) or 0 otherwise. |
