By using `WebBaseLoader`, you can load all text from webpages into a document format that we can use downstream. Web path used:

`CharacterTextSplitter` implements splitting text based on characters.
|
||
|
||
Text splitters operate as follows:
|
||
|
||
- Split the text into small, meaningful chunks (usually sentences).
|
||
|
||
- Combine these small chunks into larger ones until they reach a certain size (measured by a function).
|
||
|
||
- Once a chunk reaches the desired size, make it its piece of text and create a new chunk with some overlap to maintain context.
|
||
|
||
**Separator used**:
|
||
|
||
```txt
|
||
.
|
||
```
|
||
|
||
**Chunk size used**:
|
||
|
||
```txt
|
||
2000
|
||
```
|
||
|
||
**Chunk overlap used**:
|
||
|
||
```txt
|
||
200
|

```

The `OpenAIEmbeddings`, wrapper around [OpenAI Embeddings](https://platform.openai.com/docs/guides/embeddings/what-are-embeddings){.internal-link target=\_blank} models. Make sure to get the API key from the LLM provider, in this case [OpenAI](https://platform.openai.com/){.internal-link target=\_blank}.

`Chroma` vector databases can be used as vectorstores to conduct a semantic search or to select examples, thanks to a wrapper around them.
|
||
|

<br>
|
||
|
||
A `VectorStoreInfo` set information about the vectorstore, such as the name and description.
|
||
|
||
Name used:
|
||
|
||
```txt
|
||
ruff

||
```
|

For the example, we used `OpenAI` as the LLM, but you can use any LLM that has an API. Make sure to get the API key from the LLM provider. For example, [OpenAI](https://platform.openai.com/){.internal-link target=\_blank} requires you to create an account to get your API key.
