Question 1

How can I sync my progress across multiple devices?

Accepted Answer

Currently, CrackQuiz operates entirely locally in your browser to ensure maximum privacy. To transfer your data between devices, use the Export feature in your History page to create a JSON backup, then import it on another device. This local-first approach ensures your learning data never leaves your device and is never uploaded to external servers. Tip: Regularly export your data as a backup before clearing browser cache.

Question 2

Will I lose my data if I clear my browser cache?

Accepted Answer

Yes, because all your data (quiz history, scores, progress) is stored in your browser's local storage to protect your privacy. If you clear your browser cache, this data will be permanently deleted. To prevent data loss, we strongly recommend regularly exporting your history and quizzes to a JSON file via the Export button in your History page. You can then re-import this backup at any time. Pro tip: Create a backup before browser updates or scheduled cache cleanups.

Question 3

How do I format mathematical equations in my quizzes?

Accepted Answer

CrackQuiz natively supports LaTeX for professional-quality math rendering. Use single dollar signs `$` for inline equations (e.g., `$E = mc^2$` displays as $E = mc^2$) or double dollar signs `$$` for block equations on a separate line. Example complex equation: `$$ \int_{0}^{\infty} e^{-x^2} dx = \frac{\sqrt{\pi}}{2} $$` displays as a perfectly formatted Gaussian integral. The LaTeX rendering engine runs client-side, ensuring your mathematical formulas remain private and are never sent to external servers.

Question 4

Can I include code blocks in my quiz questions?

Accepted Answer

Yes, absolutely! CrackQuiz fully supports Markdown syntax, including syntax highlighting for code blocks. Use three backticks (```) followed by the language name to create a highlighted code block. Example: 
```python
print('Hello World')
```
Supported languages include Python, JavaScript, TypeScript, Java, C++, SQL, and many others. You can also use a single backtick `like this` for inline code. This feature is perfect for creating programming quizzes, algorithm questions, or code debugging exercises.

Question 5

How do I get API keys for OpenAI, Groq, Mistral AI, and others?

Accepted Answer

You can get your API keys from the official provider websites: OpenAI, Groq, OpenRouter, and Gemini.

Question 6

Can I generate a quiz from a PDF file?

Accepted Answer

Yes! CrackQuiz includes a built-in PDF parser that runs entirely in your browser. Simply upload your PDF slides or notes, and our local AI engine will extract the text to generate valid quiz questions instantly. This ensures your data remains private and never uploads to external servers.

Question 7

Does CrackQuiz have a CLI?

Accepted Answer

Yes, CrackQuiz offers a powerful active-recall CLI for developers. You can install it easily using package managers: run `npm install -g crackquiz` or `brew install crackquiz`. It allows you to generate and take quizzes directly from your terminal using local files.

Question 8

Which AI models does CrackQuiz support?

Accepted Answer

CrackQuiz is model-agnostic. By default, it uses privacy-first local models (WebLLM) so no data leaves your device. However, you can also connect your own API keys for Mistral AI (Le Chat) or OpenAI (GPT-4o) if you prefer cloud-based reasoning for complex topics.
