Chunk text for a retrieval pipeline
Retrieval-augmented generation needs long documents split into overlapping chunks before they are embedded and indexed. This tool splits long text into overlapping chunks for RAG and embedding pipelines, ready to index for retrieval.
Why chunking and overlap matter
A RAG system retrieves relevant passages to ground a model’s answer, and that requires documents split into pieces small enough to embed and retrieve precisely. Chunk too large and retrieval returns bloated, unfocused passages; too small and context is lost. Overlap between chunks matters because a relevant idea can straddle a boundary, and overlap ensures it appears whole in at least one chunk rather than being split across two and retrieved by neither. Getting the chunk size and overlap right is a practical foundation of a working retrieval pipeline.
Ready to index
The tool runs entirely in your browser, so nothing you paste, prompts, outputs or documents, is uploaded, which matters when the input is sensitive AI data or your own content.

Frequently Asked Questions
Why split text into chunks for RAG?
Because retrieval needs pieces small enough to embed and retrieve precisely. Whole documents are too large to match a specific query cleanly.
Why overlap the chunks?
Because a relevant idea can straddle a chunk boundary. Overlap ensures it appears whole in at least one chunk rather than being split and missed.
What is the right chunk size?
A balance: too large returns unfocused passages, too small loses context. The tool lets you set size and overlap to tune the trade-off.
What is this for?
Preparing documents for a retrieval-augmented generation or embedding pipeline, producing chunks ready to embed and index.
Is my text uploaded?
No. The chunking runs entirely in your browser.
