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.

🚀 What's New in v4.1.0

🆕 Multi-Level LLM Architecture: OpenAI → Groq → Local LLM → Fallback Plan
🆕 Local LLM Integration: Google Gemma 4 model for offline operation
🆕 Guaranteed Availability: Bot works even without internet connection
🆕 Enhanced Fallback System: Robust error handling and service switching
🆕 Improved Plan Quality: Professional-grade study plan templates
🆕 Offline Translation: Local LLM supports offline text translation

📌 Features

📚 Multi-Level LLM Architecture: Generate personalized study plans using OpenAI, Groq, Local LLM, or fallback templates
📝 Export Options: Save plans as PDF or TXT files
⏰ Smart Reminders: Receive Telegram notifications for each study step
🗄️ Lightweight Storage: TinyDB-based data storage (no SQL required)
🌐 Multilingual Support: English, Russian, Spanish with real-time LLM translation
🏷️ Reliable UI: All keyboards displayed with proper messages (no Telegram errors)
🔄 Smart Language Handling: Language selection works correctly without translation
🤖 Graceful Fallbacks: Original text sent if translation fails
🧩 Extensible Codebase: Clean, maintainable code ready for extensions
🚀 Offline Operation: Local LLM ensures 100% availability
🔒 Privacy First: Local processing keeps your data secure

🏗️ 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	Google Gemma 4 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:

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

🔄 Translation Fallback

The same multi-level system applies to text translation:

OpenAI for high-quality translations
Groq as secondary translation service
Local LLM for offline translation capability
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

Register and get your API key at Groq Console
Add to your .env file:
```
GROQ_API_KEY=your_groq_api_key
```
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 Google Gemma 4 model for offline operation:

Model: Google Gemma 4 Instruct (GGUF, quantized)
Format: GGUF format
Size: depends on variant/quantization (typically several GB)
Requirements: depends on variant (recommended 8GB+ RAM for 4B class models)

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/google-gemma-4b-it-Q4_K_M.gguf \
    "<YOUR_GEMMA4_GGUF_DOWNLOAD_URL>"

# Option 2: Using curl
curl -L -o models/google-gemma-4b-it-Q4_K_M.gguf \
    "<YOUR_GEMMA4_GGUF_DOWNLOAD_URL>"

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
LOCAL_LLM_MODEL_PATH=models/google-gemma-4b-it-Q4_K_M.gguf
LOCAL_LLM_CONTEXT=4096
LOCAL_LLM_THREADS=4
LOCAL_LLM_MAX_TOKENS=512

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.
