SnapAssist AI is a real-time AI-powered study assistant that helps students solve problems independently by giving progressive hints instead of direct answers.

Take a screenshot of a question (assignments, PDFs, exams, etc.). SnapAssist will:

• Detect the screenshot from the clipboard
• Extract text via OCR (Tesseract)
• Classify the question (MCQ or Descriptive) and estimate difficulty
• Query an AI model (Ollama locally, or Gemini via API) to generate stepwise hints
• Show hints in a simple GUI, or print them in headless mode

✨ Features

• 📸 Cross-platform screenshot detection – Uses clipboard on macOS, Windows, and Linux
• 🔎 OCR with Tesseract – Robust text extraction via pytesseract
• 🧩 Question classification – MCQ vs. descriptive
• ⚖️ Difficulty estimation – Easy / Medium / Hard
• 🤖 LLM provider selection – Local via Ollama, or cloud via Gemini
• ⬇️ Auto-pull Ollama model – Ensures the selected model is available before first use
• 🔐 Keychain storage – Saves Gemini API key securely via keyring (one-time setup)
• 🖥️ GUI or headless – Tkinter GUI if available, otherwise prints to console
• Beautiful, distraction-free UI with styled hints (bold labels, soft colors)

📦 Installation (Users)

Install from PyPI (recommended):

pip install -U hintify

Then start:

hintify

2. Install Tesseract (required)

• macOS: brew install tesseract
• Windows: choco install tesseract (or download from the UB Mannheim builds)
• Linux: sudo apt-get install tesseract-ocr (or your distro equivalent)

3. Option A: Local via Ollama (recommended for offline)

• Install Ollama from: https://ollama.com/download
• The app will auto-pull the model on first run

If you prefer source install:

pip install -r requirements.txt
python hintify.py

4. Option B: Gemini API (cloud)

• Get an API key from Google AI Studio: https://aistudio.google.com/apikey
• The app will offer to open the page and save your key securely on first run

🚀 Quickstart

Run from terminal after install:

hintify

Hotkeys:

• macOS (global): Cmd+Shift+H to capture (may require Accessibility permission)
• Windows (global): Ctrl+Shift+H to capture (opens Snipping Tool)
• In-app: press 'c' while the window is focused, or click Capture

Headless mode (no tkinter installed):

python hintify.py --no-gui

Take a screenshot and copy it to the clipboard. Hints will appear automatically.

• GUI extras:
  • Click the "Capture (press 'c')" button or press 'c' while the window is focused to select an area and process it immediately (macOS).

⚙️ Configuration

CLI options:

python hintify.py \
  --provider {ollama|gemini} \
  --ollama-model granite3.2-vision:2b \
  --gemini-model gemini-2.0-flash \
  --poll-interval 1.5 \
  --no-gui

Environment variables:

• HINTIFY_PROVIDER – Force provider (ollama or gemini)
• HINTIFY_OLLAMA_MODEL – Ollama model ID (default granite3.2-vision:2b)
• GEMINI_API_KEY – Gemini API key
• GEMINI_MODEL – Gemini model ID (default gemini-2.0-flash; auto-fallback to gemini-1.5-flash)

Provider behavior:

• If Ollama is installed, the app uses Ollama and auto-pulls the model if missing
• If Ollama is not installed, the app offers Gemini setup, opens the API key page, and saves the key in the system keychain
• If both are available, you can select via --provider or HINTIFY_PROVIDER

Key storage:

• Gemini key is stored securely with keyring (service = hintify, username = gemini_api_key)
• To clear the saved key:

python -c "import keyring; keyring.delete_password('hintify','gemini_api_key')"

🔄 How it Works

1. Monitor clipboard for images
2. OCR with Tesseract
3. Classify question type and difficulty
4. Build a “hints-only” prompt
5. Query Ollama or Gemini
6. Show 3–5 progressive hints (concept → formula → setup → approach → nudge)

---

🧰 Troubleshooting

• Tesseract not found: install it and ensure tesseract is on PATH (see Installation)
• Clipboard returns None on Linux: ensure a desktop environment/clipboard manager is running
• Ollama not found: install from https://ollama.com/download
• Gemini 2.5 model not available to your account: the app auto-falls back to gemini-1.5-flash
