About Text Chunker

Splits long documents into overlapping chunks for embeddings and RAG pipelines, using the same recursive paragraph, sentence, and word boundaries a production splitter would apply.

Key Features

Recursive, paragraph, sentence, markdown-heading, and fixed-window split strategies
Configurable overlap in characters or approximate tokens so context survives chunk boundaries
Exports labelled text, a JSON array, or JSONL ready to feed an embedding job
Handles files up to 100 MB with per-chunk size stats and token estimates

Use Cases

Prepare documentation for a vector database before embedding
Tune chunk size and overlap against a real document instead of guessing
Break a transcript or long article into model-sized pieces for summarisation

About the token estimate

Token counts here are approximated at four characters per token, which tracks English prose closely but drifts on code, JSON, and non-Latin scripts. Boundaries are exact: with overlap set to zero and trimming off, concatenating the chunks reproduces your source text character for character. With overlap on, each chunk repeats the tail of the one before it.

Privacy & Security

All processing happens locally in your browser. Your data never leaves your computer, ensuring complete privacy and security.
