**paperless-gpt** is a tool designed to generate accurate and meaningful document titles for [paperless-ngx](https://github.com/paperless-ngx/paperless-ngx) using Large Language Models (LLMs). It supports multiple LLM providers, including **OpenAI** and **Ollama**. With paperless-gpt, you can streamline your document management by automatically suggesting appropriate titles based on the content of your scanned documents.

## Getting Started

### Prerequisites

- [Docker](https://www.docker.com/get-started) installed on your system.
- A running instance of [paperless-ngx](https://github.com/paperless-ngx/paperless-ngx).
- Access to an LLM provider:
  - **OpenAI**: An API key with access to models like `gpt-4o` or `gpt-3.5-turbo`.
  - **Ollama**: A running Ollama server with models like `llama2` installed.

### Installation

#### Docker Compose

The easiest way to get started is by using Docker Compose. Below is an example `docker-compose.yml` file to set up paperless-gpt alongside paperless-ngx.

```yaml
version: '3.7'
services:
  paperless-ngx:
    image: ghcr.io/paperless-ngx/paperless-ngx:latest
    # ... (your existing paperless-ngx configuration)

  paperless-gpt:
    image: icereed/paperless-gpt:latest
    environment:
      PAPERLESS_BASE_URL: 'http://paperless-ngx:8000'
      PAPERLESS_API_TOKEN: 'your_paperless_api_token'
      LLM_PROVIDER: 'openai' # or 'ollama'
      LLM_MODEL: 'gpt-4o'     # or 'llama2'
      OPENAI_API_KEY: 'your_openai_api_key' # Required if using OpenAI
      LLM_LANGUAGE: 'English' # Optional, default is 'English'
      OLLAMA_HOST: http://host.docker.internal:11434 # Useful if using Ollama
    ports:
      - '8080:8080'
    depends_on:
      - paperless-ngx
```

**Note:** Replace the placeholder values with your actual configuration.
