What’s included

Side Panel UI (with popup fallback)
Math assistant:
- Generate steps (auto-expanding list)
- Hint me
- Check answer (result appears only in the Check box)
General tools:
- Translate (no network, works everywhere)
- Extract highlights (no network, works everywhere)
- Summarize / Rewrite (require on-device AI if available)
Theme: Light / Dark / System
Privacy-first: no data leaves the device; AI is opt-in

Quick start (Developer mode)

Open chrome://extensions → enable Developer mode.
Click Load unpacked → select the extension/ folder.
Highlight text on any page → Right-click → Send selection → Web-to-Quest.
The side panel (or popup fallback) opens with your selection prefilled.

How to use

General tab

Paste or send text into Input.
Choose one action:
- Translate (works offline)
- Extract (works offline)
- Summarize / Rewrite (AI-gated; see below)
Results appear in Result.

Math tab

Paste or send the math expression into Problem.
Click Generate steps and / or Hint me.
Enter your answer → Check answer (only here is the correct value shown).
Generate printable variants drafts similar problems (no answers).

Built-in AI (Gemini Nano) — optional

Web-to-Quest works 100% without AI: math steps / hints / checks, Translate, and Extract are fully local.
If Chrome exposes on-device Gemini Nano (Prompt API), Summarize and Rewrite enable automatically.

Enable (if you want AI):

Use Chrome Canary and flags as described in extension/help/ai.html.
Open the side panel DevTools and run:
```
await window.ai?.canCreateTextSession?.()
```
You might see: ready (enabled), after-download (model fetching), or missing/unavailable (no AI).

(Graceful degradation: when AI isn’t available, those buttons stay disabled and everything else still works.)

Permissions

sidePanel — open the Web-to-Quest panel
contextMenus — add Send selection → Web-to-Quest
storage — pass selection text from background to panel safely

No host_permissions are requested.

Privacy

All computation runs locally in the extension’s process.
We do not collect, transmit, or store personal data or analytics.
Selection text is cached briefly in chrome.storage.session (with chrome.storage.local as a fallback) only to pass data from background → side panel, then overwritten on the next selection.
AI features are opt-in; when enabled they use Chrome’s on-device Gemini Nano (no network calls).

Development

Source lives under /extension.
On tags matching v*.*.*, GitHub Actions can package the build (see .github/workflows/*).

Typical flow:

# from repo root
npm run lint     # (if you add tooling)
# load /extension in chrome://extensions

Troubleshooting

Panel didn’t appear – It may open as a popup (fallback). You can also click the extension icon to open the panel.
“AI: unavailable” – Summarize/Rewrite are disabled; the rest still works.
Context menu didn’t appear – Reload the extension or right-click in a standard text selection area.

Roadmap

Expand the printable-variants generator
More extractors on the General tab
Optional in-panel tutorial cards
