Import unstructured data (text and images) into structured tables

## Installation

Install this plugin in the same environment as [Datasette](https://datasette.io/).
```bash
datasette install datasette-extract
```

## Configuration

This plugin requires an [OpenAI API key](https://platform.openai.com/api-keys).

You can set this using the `DATASETTE_SECRETS_OPENAI_API_KEY` environment variable, or you can configure the [datasette-secrets](https://github.com/datasette/datasette-secrets) plugin to allow users to enter their own plugin and save it, encrypted, in their database.

Here's how to start using Datasette with that environment variable:

```bash
DATASETTE_SECRETS_OPENAI_API_KEY="xxx" datasette data.db --root --create
# Now click or command-click the URL containing .../-/auth-token?token=...
```
- Replace `xxx` with your OpenAI API key
- The `--root` flag causes Datasette to output a link that will sign you in as root
- The `--create` flag will create the `data.db` SQLite database file if it does not exist

If you are using other models from plugins you should consult those LLM plugins for documentation on how to configure their API keys, if they need one.

By default all asyncio and schema supporting LLM models will be provided as options for the user. You can restrict that to a subset of models using the `models` setting:

```yaml
plugins:
 datasette-extract:
  models:
  - openai/gpt-4.1-nano
```
If you only list a single model users will not get an option to select the model when they use the extraction tool.

## Usage

This plugin provides the following features:

- In the database action cog menu for a database select "Create table with extracted data" to create a new table with data extracted from text or an image
- In the table action cog menu select "Extract data into this table" to extract data into an existing table

When creating a table you can specify the column names, types and provide an optional hint (like "YYYY-MM-DD" for dates) to influence how the data should be extracted.

When populating an existing table you can provide hints and select which columns should be populated.

Text input can be pasted directly into the textarea.

Drag and drop a PDF or text file onto the textarea to populate it with the contents of that file. PDF files will have their text extracted, but only if the file contains text as opposed to scanned images.

Drag and drop a single image onto the textarea - or select it with the image file input box - to process an image.

## Permissions

Users must have the `datasette-extract` permission to use this tool.

In order to create tables they also need the `create-table` permission.

To insert rows into an existing table they need `insert-row`.

Run this to grant those permissions to the root user:
```bash
datasette . --root \
  -s permissions.insert-row.id root \
  -s permissions.create-table.id root \
  -s permissions.datasette-extract.id root \
```

## Development

To set up this plugin locally, first checkout the code. Then create a new virtual environment:
```bash
cd datasette-extract
python3 -m venv venv
source venv/bin/activate
```
Now install the dependencies and test dependencies:
```bash
pip install -e '.[test]'
```
To run the tests:
```bash
pytest
```
One option to run this in development is to use this recipe:
```bash
DATASETTE_SECRETS_OPENAI_API_KEY="$(llm keys get openai)" \
  datasette . --root --secret 1 \
  -s permissions.insert-row.id root \
  -s permissions.create-table.id root \
  -s permissions.datasette-extract.id root \
  -s plugins.datasette-extract.models '["openai/gpt-4.1-nano", "openai/gpt-4.1-mini"]' \
  --internal internal.db --reload
```
