**Transform raw text into structured, formatted content for WriteFreely and beyond.**

`write_struct` is a Python package designed to enhance content creation by automatically converting user-submitted text into well-structured, formatted output. It leverages AI-powered pattern matching to ensure consistency, readability, and publication-ready quality for articles, blog posts, social media updates, and more.

---

## 🚀 Features
- **Automated text structuring** using AI-driven pattern matching.
- **Flexible LLM integration** – works with default `ChatLLM7` or any LangChain-compatible model.
- **Regex-based validation** to enforce output consistency.
- **Lightweight and efficient** for text-based content processing.
- **No multimedia handling** – focuses purely on text formatting.

---

## 📦 Installation

Install via pip:

```bash
pip install write_struct
```

---

## 🔧 Usage

### Basic Usage (Default LLM7)
```python
from write_struct import write_struct

user_input = "Your raw text here..."
response = write_struct(user_input)
print(response)
```

### Custom LLM Integration
You can replace the default `ChatLLM7` with any LangChain-compatible model (e.g., OpenAI, Anthropic, Google Generative AI):

#### Using OpenAI:
```python
from langchain_openai import ChatOpenAI
from write_struct import write_struct

llm = ChatOpenAI()
response = write_struct(user_input, llm=llm)
```

#### Using Anthropic:
```python
from langchain_anthropic import ChatAnthropic
from write_struct import write_struct

llm = ChatAnthropic()
response = write_struct(user_input, llm=llm)
```

#### Using Google Generative AI:
```python
from langchain_google_genai import ChatGoogleGenerativeAI
from write_struct import write_struct

llm = ChatGoogleGenerativeAI()
response = write_struct(user_input, llm=llm)
```

---

## 🔑 API Key Configuration
- **Default**: Uses `LLM7_API_KEY` from environment variables.
- **Manual Override**: Pass the API key directly:
```python
response = write_struct(user_input, api_key="your_api_key_here")
```
- **Free API Key**: Register at [https://token.llm7.io/](https://token.llm7.io/) for LLM7.

---

## 📜 Input Parameters
| Parameter | Type | Description |
|-----------|------------|-----------------------------------------------------------------------------|
| `user_input` | `str` | Raw text to be structured. |
| `api_key` | `Optional[str]` | LLM7 API key (defaults to `LLM7_API_KEY` env var). |
| `llm` | `Optional[BaseChatModel]` | Custom LangChain LLM (e.g., `ChatOpenAI`, `ChatAnthropic`). Defaults to `ChatLLM7`. |

---

## 📊 Rate Limits
- **LLM7 Free Tier**: Sufficient for most use cases.
- **Upgrade**: For higher limits, use a custom API key or switch to a paid plan.
