Embedchain supports following data formats:

### Youtube video

To add any youtube video to your app, use the data_type (first argument to `.add()` method) as `youtube_video`. Eg:

```python
app.add('youtube_video', 'a_valid_youtube_url_here')
```

### PDF file

To add any pdf file, use the data_type as `pdf_file`. Eg:

```python
app.add('pdf_file', 'a_valid_url_where_pdf_file_can_be_accessed')
```

Note that we do not support password protected pdfs.

### Web page

To add any web page, use the data_type as `web_page`. Eg:

```python
app.add('web_page', 'a_valid_web_page_url')
```

### Sitemap

Add all web pages from an xml-sitemap. Filters non-text files. Use the data_type as `sitemap`. Eg:

```python
app.add('sitemap', 'https://example.com/sitemap.xml')
```

### Doc file

To add any doc/docx file, use the data_type as `docx`. Eg:

```python
app.add('docx', 'a_local_docx_file_path')
```

### Code documentation website loader

To add any code documentation website as a loader, use the data_type as `docs_site`. Eg:

```python
app.add("docs_site", "https://docs.embedchain.ai/")
```

### Notion
To use notion you must install the extra dependencies with `pip install embedchain[notion]`.

To load a notion page, use the data_type as `notion`.
The next argument must **end** with the `notion page id`. The id is a 32-character string. Eg:

```python
app.add("notion", "cfbc134ca6464fc980d0391613959196")
app.add("notion", "my-page-cfbc134ca6464fc980d0391613959196")
app.add("notion", "https://www.notion.so/my-page-cfbc134ca6464fc980d0391613959196")
```

### Text

To supply your own text, use the data_type as `text` and enter a string. The text is not processed, this can be very versatile. Eg:

```python
app.add_local('text', 'Seek wealth, not money or status. Wealth is having assets that earn while you sleep. Money is how we transfer time and wealth. Status is your place in the social hierarchy.')
```

Note: This is not used in the examples because in most cases you will supply a whole paragraph or file, which did not fit.

### QnA pair

To supply your own QnA pair, use the data_type as `qna_pair` and enter a tuple. Eg:

```python
app.add_local('qna_pair', ("Question", "Answer"))
```

## Reusing a vector database

Default behavior is to create a persistent vector DB in the directory **./db**. You can split your application into two Python scripts: one to create a local vector DB and the other to reuse this local persistent vector DB. This is useful when you want to index hundreds of documents and separately implement a chat interface.

Create a local index:

```python
from embedchain import App

naval_chat_bot = App()
naval_chat_bot.add("youtube_video", "https://www.youtube.com/watch?v=3qHkcs3kG44")
naval_chat_bot.add("pdf_file", "https://navalmanack.s3.amazonaws.com/Eric-Jorgenson_The-Almanack-of-Naval-Ravikant_Final.pdf")
```

You can reuse the local index with the same code, but without adding new documents:

```python
from embedchain import App

naval_chat_bot = App()
print(naval_chat_bot.query("What unique capacity does Naval argue humans possess when it comes to understanding explanations or concepts?"))
```

### More formats (coming soon!)

- If you want to add any other format, please create an [issue](https://github.com/embedchain/embedchain/issues) and we will add it to the list of supported formats.
