Quickstart

Requirements

• Node.js 18+
• Chrome or Chromium-based browser
• An API key for at least one AI provider (Gemini, OpenAI, Anthropic, Perplexity, or OpenRouter)

Build the Extension

1. Install dependencies

npm install

2. Build production assets (outputs dist/)

npm run build

Load in Chrome (Unpacked)

1. Open chrome://extensions
2. Enable Developer Mode (top-right)
3. Click "Load unpacked"
4. Select the dist folder created by the build

The Quanta extension should now appear in your extensions list.

Configure Provider & Model

1. Click the Quanta icon to open the popup
2. Choose an AI provider and paste your API key
3. Pick a model. Quanta can fetch the latest models from OpenAI/OpenRouter and caches results smartly to avoid rate limits
4. Save

Notes:

• OpenRouter may show free models by default; use the custom model field for premium models
• Gemini includes a Reasoning Effort control (Auto, Off, Low, Medium, High)

Using Quanta on a Quiz

1. Navigate to a Moodle quiz page
2. Quanta automatically detects questions and injects a "Get Answer with Quanta" button per question
3. Click the button to get an answer; Quanta will select and highlight the predicted answer(s)

Bulk Answering

Quanta can answer multiple questions sequentially with auto-resume and a reliable stop mechanism. Configure behavior in the main settings panel:

• Start/stop bulk mode
• Resume after interruptions
• Error handling preferences

Session Memory

Starting in 1.4.2, Quanta maintains context across questions within a quiz session to improve consistency.

Stealth Mode

Hide explanations and highlights while keeping auto-answer enabled.

Troubleshooting

• If models don’t appear, recheck provider keys and network, then reopen the popup
• For checkbox questions with ARIA labels, Quanta includes improved dispatching to ensure Moodle recognizes changes (1.2.9)
• See the Changelog for recent fixes and improvements
