Browser extension

The browser extension is the individual-user product. Install once and get accessibility tools on every site you visit.

Install

• Edge → Edge Add-ons listing (coming soon)
• Firefox → Firefox Add-ons listing (coming soon)

7 built-in capabilities across vision, motor, and cognitive modalities:

Voice command	Motor	Yes
High contrast	Vision	No (CSS injection)

Local dev

Until the store listings are live:

git clone https://github.com/webdevhari/wholisphere
cd wholisphere/agent
pnpm install
pnpm --filter @wholisphere/extension build
# Then in Chrome:
#   chrome://extensions → enable Developer mode → Load unpacked
#   → pick agent/apps/extension/.output/chrome-mv3

Permissions

The extension requests:

• storage — to remember your preferences
• activeTab — to know which page the popup is for
• scripting — reserved for future on-demand injection
• <all_urls> — required because the widget mounts on any page you visit

We do not collect any data without explicit telemetry opt-in. Audit log lives locally in chrome.storage.local and you can export or clear it from the popup.

Settings

Open the popup (extension icon) to adjust:

• Backend URL (defaults to http://127.0.0.1:8787 in local dev)
• Widget position
• Keyboard shortcut
• Speech rate
• Telemetry opt-in

Recent activity

The popup shows the last 50 agent actions: capability, timestamp, host. Export as JSON for your own audit; clear at any time.
