+
+Many of the most important LLM applications involve connecting LLMs to external sources of data.
+A prerequisite to doing this is to ingest data into a format where LLMs can easily connect to them.
+Most of the time, that means ingesting data into a vectorstore.
+A prerequisite to doing this is to split the original text into smaller chunks.
+
+While this may seem trivial, it is a nuanced and overlooked step.
+When splitting text, you want to ensure that each chunk has cohesive information - e.g. you don't just want to split in the middle of sentence.
+What "cohesive information" means can differ depending on the text type as well.
+For example, with Markdown you have section delimiters (`##`) so you may want to keep those together, while for splitting Python code you may want to keep all classes and methods together (if possible).
+
+This repo (and associated Streamlit app) are designed to help explore different types of text splitting.
+You can adjust different parameters and choose different types of splitters.
+By pasting a text file, you can apply the splitter to that text and see the resulting splits.
+You are also shown a code snippet that you can copy and use in your application
+
+## Hosted App
+
+To use the hosted app, head to [https://langchain-text-splitter.streamlit.app/](https://langchain-text-splitter.streamlit.app/)
+
+## Running locally
+
+To run locally, first set up the environment by cloning the repo and running:
+
+```shell
+pip install -r requirements
+```
+
+Then, run the Streamlit app with:
+
+```shell
+streamlit run splitter.py
+```
