EinkBro is a full-featured Android WebView-based browser specifically optimized for e-ink displays. It provides a rich reading experience with features like ad blocking (via a native C++ engine forked from Brave), paragraph-level translation (Google/DeepL/OpenAI/Gemini), text-to-speech (Edge TTS, system TTS, Web Speech polyfill), reader mode, EPUB reading, user script support, and AI agent capabilities (chat-with-web, multi-step browsing tasks). The architecture is a monolith Android app with three Gradle modules (app, ad-filter, adblock-client) using Kotlin, Jetpack Compose, Koin DI, Room database, and OkHttp. Key entry points include BrowserActivity (main browser), EBWebView (custom WebView wrapper), and various delegate classes for tab management, translation, AI chat, and gesture handling. The codebase demonstrates strong engineering practices with extensive unit tests, a well-structured delegate pattern, and several reusable components such as type-safe SharedPreferences delegates, a standalone PDF parser, and a jsdom-based test harness for WebView-injected JavaScript.
