## 🔧 Installation

### 1️⃣ Clone the repo

```bash
git clone https://github.com/JustinOros/telegram-bot.git
cd telegram-bot
```

### 2️⃣ Install dependencies

```bash
pip install -r requirements.txt
```

### 3️⃣ Run the bot

```bash
python3 telegram-bot.py
```

On first run, it will prompt you for:

* OpenAI API Key
* Telegram Bot Token

It will then create a `.env` file automatically.

---

## 🔐 Environment Variables

The bot uses a `.env` file:

```
OPENAI_API_KEY=your_openai_key
TELEGRAM_BOT_TOKEN=your_telegram_bot_token
```

⚠️ Important:
Make sure `.env` is included in `.gitignore` so you never upload your API keys.

---

## 🎭 Personality Customization

The bot loads its personality from:

```
personality.txt
```

If it doesn’t exist, a default one is created automatically.

You can edit this file to change the bot’s tone, for example:

* More sarcastic
* More professional
* More flirty
* Super minimal replies
* Long-form explanations

---

## 🧠 Style Mirroring System

The bot automatically:

* Matches capitalization
* Matches punctuation usage
* Matches grammar looseness
* Uses the same shorthand (u, rn, idk, lmk, etc.)
* Matches message length & energy

It does this dynamically per message.
