duckAssist

Lightweight, privacy-focused WebView wrapper for Duck.ai
duckAssist is a lightweight, privacy-focused Android WebView wrapper designed specifically for Duck.ai (DuckDuckGo's private AI chat service). It bridges the gap between web and native by providing advanced integration features while maintaining the core privacy principles of DuckDuckGo.

Key Features:
- Focused Interface: A clean, distraction-free environment tailored for AI chat, complete with a native progress bar.
- Digital Assistant Integration: Set duckAssist as your device's default digital assistant app for instant access.
- Auto-Voice Activation: Launching via the assistant shortcut automatically triggers a new voice chat.
- "Ask duck.ai" Integration: Select text in any application and choose "Ask duck.ai" from the context menu to paste your query directly.
- Smart Link Handling: External links open automatically in your system's default browser.
- Enhanced Privacy: Session persistence is preserved, and the application cache is automatically purged when leaving/closing the app.
- Native File Support: Seamlessly upload documents and download attachments.
- Bottom Drawer Interface: Slide up a convenient bottom sheet drawer when using assistant shortcuts or sharing content to interact with the AI without losing your background app context.
- Customizable Prompts & UI Settings: Configure bottom drawer panel behavior, assistant voice options, and default prompt suffixes for text and document sharing via a custom-styled HTML settings page.
