EduPlannerBotAI is a Telegram bot built with aiogram 3.x and powered by a 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).

Developed for ForgeFlow Tech: https://www.upwork.com/agencies/2050880168568328242/

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: OpenAI → Groq → Local LLM → Fallback Plan

• 📝 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

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

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 (Google Gemma 4 model)
4. Last Resort: Local plan generator (comprehensive template)

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

• 🔄 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

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

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

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

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

• 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

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

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

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.

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.

python bot.py

Run the bot in a container:

docker-compose up --build

Environment variables are loaded from .env.

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.
