tool
RAG chunk-size visualizer
A browser tool that splits a document into chunks at different sizes and overlaps, so you can see how chunking changes what a retriever would return — before you build the pipeline.
Why we built this
Chunking is the first knob teams get wrong on a RAG system. Pick chunks too large and retrieval pulls in noise; too small and you shred the context a passage needs to make sense. Most people tune it by feel, rebuild the index, and guess whether it got better.
What it shows
Paste in a document, set a chunk size and overlap, and the tool draws the actual splits — where each chunk starts and ends, and what overlaps with what. Seeing the boundaries makes the trade-off concrete: you can watch a heading get separated from its paragraph, or a table get cut in half, and adjust before any of it reaches a retriever.
It’s intentionally small and runs entirely in the browser — nothing is uploaded.
