FAQ
Here are answers to some frequently asked questions about Quanta.
Q: What exactly is Quanta?
Quanta is a browser extension that sends quiz questions (primarily on Moodle) to an AI provider and returns suggested answers for you to review before submitting.
Q: Do I need an API key to use Quanta?
Yes. Provide your own API key for one of the supported providers (Google Gemini, OpenAI, Anthropic, Perplexity, or OpenRouter). The key is required because quiz content is sent to these services to generate answers.
Q: Is my API key safe?
Your key stays in your browser's local storage and is only sent to the provider you configure. Quanta does not forward keys to its own servers or third parties.
Q: What AI models can I use?
Quanta supports models from Google Gemini, OpenAI, Anthropic, Perplexity, and OpenRouter. Model lists from OpenAI and OpenRouter are fetched dynamically so new options appear without an extension update.
Privacy note
API keys remain in local storage and are only sent to the provider APIs you configure. Quanta does not transmit keys elsewhere.
Q: Does Quanta work on all websites?
Quanta is built for Moodle quizzes. It may work on other quiz platforms with similar structures, but compatibility is not guaranteed.
Q: What happens if the AI gets the answer wrong?
AI responses can be wrong. Review suggestions before submitting your quiz.
Q: How does Quanta handle questions that load dynamically?
Quanta uses a MutationObserver to detect new question elements and inject the "Get Answer with Quanta" button even when quizzes load content after the initial page load.
Q: What about accessibility and compatibility?
Quanta interacts with Moodle's native inputs and uses ARIA-conscious updates so the platform registers selections. If you see an accessibility issue, report it with repro steps via feedback.
Q: What should I do if the extension isn't working?
Confirm your API key in the popup, then check the browser console for errors. If issues persist, submit a report via feedback with details and screenshots.
Quick fixes
- Verify your provider key and model selection.
- Try another provider if requests keep failing.
- Reopen the popup after entering keys to refresh cached model lists.
Q: How does the Answer Vault work?
The Answer Vault (v1.5.0+) lets users vote on answer options. Mark choices as correct (👍🏻) or wrong (👎🏻); votes sync in real time across users. Consensus scoring blends community votes with AI predictions.
Q: Are my votes anonymous?
Yes. The system stores vote counts and question/answer text only—no user identifiers, emails, IPs, or personal information are collected.
Q: How do I vote on answers?
You can vote in two ways:
- Inline buttons: Use the 👍🏻/👎🏻 buttons next to each answer option while taking a quiz (toggle visibility in Settings → Behavior)
- Answer Vault page: Click the Quanta icon → Answer Vault tab to view all questions and vote on options
Votes sync in real time across users and browser tabs.
Q: Why aren't my votes appearing?
Votes require a live connection. If they still don't appear:
- Refresh the page to resync
- Check the browser console for connection errors
- Confirm you're on v1.5.0+ (includes vote persistence fixes)
Q: Can I hide the vote buttons?
Yes! Go to Main Settings → Behavior tab → toggle "Show Vote Buttons" to hide the inline voting buttons. You can still access voting functionality through the Answer Vault page in the extension popup.
Q: What if the community votes for the wrong answer?
Community votes are just one data source. Quanta combines them with AI predictions using balanced scoring, so a few incorrect votes won't override strong AI confidence. You can always vote to correct inaccurate community answers and help improve the vault quality.
Q: What is Streamdown and how does it improve Quanta?
Streamdown (v1.5.0) is the markdown renderer that replaced KaTeX. It supports:
- LaTeX math - Formulas like
- Code highlighting - 100+ programming languages
- Mermaid diagrams - Flowcharts, sequence diagrams, class diagrams
- GitHub Flavored Markdown - Tables, task lists, rich formatting
This keeps AI explanations readable and properly formatted.
Q: How do I get the AI to use LaTeX or code blocks in explanations?
Just ask normally. For math questions, responses include LaTeX; for programming questions, code uses syntax highlighting. You can also request diagrams or code explicitly.
Q: Can I use markdown formatting in quiz questions?
Yes! Quanta's React-based markdown injection system renders markdown/LaTeX content directly in quiz questions and answer options. This is especially useful for technical quizzes with mathematical formulas or code snippets.
