EduPlannerBotAI

EduPlannerBotAI is a Telegram bot built with aiogram 3.x and powered by a revolutionary multi-level LLM architecture. It generates personalized study plans, exports them to PDF/TXT, and sends reminders as Telegram messages. All data is stored using TinyDB (no other DBs supported).

Note: All code comments and docstrings are in English for international collaboration and code clarity. All user-facing messages and buttons are automatically translated to the user's selected language.

🏗️ Multi-Level LLM Architecture

The bot features a sophisticated 4-tier fallback system that ensures reliable service even during complete internet outages:

🎯 LLM Processing Chain

Priority	Service	Description	Use Case
1	OpenAI GPT	Primary model for high-quality plans	Best quality, when available
2	Groq	Secondary model, OpenAI alternative	Fast fallback, reliable service
3	Local LLM	TinyLlama 1.1B local model	Offline operation, privacy
4	Fallback Plan	Predefined professional template	Guaranteed availability

⚡ How It Works

The bot automatically attempts to generate study plans using available services in order of priority:

1. Primary: OpenAI API (if OPENAI_API_KEY is set and quota available)
2. Fallback 1: Groq (if GROQ_API_KEY is set)
3. Fallback 2: Local LLM (TinyLlama 1.1B model)
4. Last Resort: Local plan generator (comprehensive template)

🔄 Translation Fallback

The same multi-level system applies to text translation:

1. OpenAI for high-quality translations
2. Groq as secondary translation service
3. Local LLM for offline translation capability
4. Original Text if all translation services fail

🤖 Local LLM Integration

✨ Key Benefits

• 🔄 Offline Operation: Works without internet connection
• ⚡ Fast Response: No network latency (0.5-2 seconds)
• 🔒 Privacy: All processing happens locally on your server
• 🛡️ Guaranteed Availability: Always accessible as fallback
• 🎯 High Quality: Professional-grade study plan generation
• 💰 Cost Effective: No API costs for local operations

📊 Performance Metrics

Metric	OpenAI	Groq	Local LLM	Fallback
Response Time	2-5s	1-3s	0.5-2s	0.1s
Availability	99%	99%	100%	100%
Cost	Per token	Per token	Free	Free
Privacy	External	External	Local	Local

🆕 Groq Fallback Integration

If the OpenAI API is unavailable, out of quota, or not configured, the bot automatically uses Groq as a fallback LLM provider.

🚀 Groq Advantages

• Fast and reliable generations
• No strict quotas for most users
• OpenAI-compatible API
• Always available fallback

📝 Setup Instructions

1. Register and get your API key at Groq Console
2. Add to your .env file:

   GROQ_API_KEY=your_groq_api_key

3. No other changes needed — automatic fallback enabled

🌐 Multilingual Support

Choose your preferred language for all bot interactions! Use /language to select from:

Language	Code	Status
English	en	✅ Primary
Русский	ru	✅ Full support
Español	es	✅ Full support

🔄 Translation Features

• Real-time translation using multi-level LLM system
• Context-aware results for better accuracy
• Automatic fallback through available services
• Original text preservation if translation fails

🚀 Quick Start

1. Clone the project

git clone https://github.com/AlexTkDev/EduPlannerBotAI.git
cd EduPlannerBotAI

2. Install dependencies

python -m venv .venv
source .venv/bin/activate   # Windows: .venv\Scripts\activate
pip install -r requirements.txt

3. Set up Local LLM (Recommended)

The bot includes a local TinyLlama 1.1B model for offline operation:

• Model: TinyLlama 1.1B Chat v1.0 (Q4_K_M quantized)
• Format: GGUF format
• Size: ~1.1GB
• Requirements: ~2GB RAM for optimal performance

Important: The model file is not included in the repository due to size limitations. You must download it separately:

# Download the model (choose one method)
# Option 1: Using wget
wget -O models/tinyllama-1.1b-chat-v1.0.Q4_K_M.gguf \
    "https://huggingface.co/TheBloke/TinyLlama-1.1B-Chat-v1.0-GGUF/resolve/main/tinyllama-1.1b-chat-v1.0.Q4_K_M.gguf"

# Option 2: Using curl
curl -L -o models/tinyllama-1.1b-chat-v1.0.Q4_K_M.gguf \
    "https://huggingface.co/TheBloke/TinyLlama-1.1B-Chat-v1.0-GGUF/resolve/main/tinyllama-1.1b-chat-v1.0.Q4_K_M.gguf"

See models/README.md for detailed download instructions and troubleshooting.

The model is automatically loaded at startup and provides offline fallback capability.

4. Create .env file

Create a .env file in the root directory or rename .env.example to .env and fill in your tokens:

BOT_TOKEN=your_telegram_bot_token
OPENAI_API_KEY=your_openai_api_key
GROQ_API_KEY=your_groq_api_key

All environment variables are loaded from .env automatically.

5. Run the bot

python bot.py

🐳 Docker Deployment

Run the bot in a container:

docker-compose up --build

Environment variables are loaded from .env.

🔔 How Reminders Work

When you choose to schedule reminders, the bot sends a separate Telegram message for each study plan step, ensuring timely notifications directly in your chat.

🧪 Testing & Code Quality
