Rag Chunking Playground

RAG Chunking Playground is a browser-based visual tool for comparing document chunking strategies used in retrieval-augmented generation. It displays chunk boundaries, offers quality grading and a BM25-ranked query view, and lists cost estimates and code export for RAG frameworks.

Practical overview

When it fits

Use it while exploring or evaluating chunking choices for a RAG workflow, especially when you want to inspect actual boundaries or see which chunks rank for a sample query.

Who it is for

  • RAG developers comparing how splitting choices affect their documents.
  • Learners exploring chunking concepts through visual examples.
  • Teams reviewing chunk boundaries and retrieval selections before implementation.

Documented uses

  • Compare documented chunking approaches side by side.
  • Find awkward or broken boundaries in document chunks.
  • Inspect chunks ranked for a sample query using BM25.
  • Review listed embedding and context-window cost estimates and integration code exports.
Before you choose

Requirements & limits

The project documents a live web tool and a public repository under the MIT License. Its README also describes opening index.html locally without a build step or dependencies.

  • The README lists semantic chunking as coming soon, despite including it among six strategies.
  • The project describes token counts as GPT-3 estimates, using approximately one token per four characters.
  • The README says processing is client-side and identifies semantic processing as an OpenAI API exception, while that capability is marked as coming soon.
  • Listed cost estimates and strategy scores are project documentation, not a guarantee of performance or cost for a particular system.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Open the project locally

Set up the repository's browser-based playground from its documented HTML entry point.

Before you start

  • Git
  • A web browser

Steps

  1. Clone the public repository.

  2. Change into the repository directory.

  3. Open index.html in a browser.

Expected outcome

The README describes the local tool as opening in a browser without a build step or dependencies.

Guide limitations

  • This guide covers the documented local setup only, not a particular comparison or result.
  • The README describes semantic chunking as coming soon.
