## What it is
EinkBro is a lightweight, fast Android web browser built on Android WebView, optimized for E-Ink devices with zero animations, high-contrast UI, and e-paper-friendly reading features. It also works well on regular Android devices, offering reader mode, EPUB export, userscripts, ad blocking, and AI-powered page chat and summarization.

## Use cases
- browse the web on an e-ink e-reader android device
- read articles distraction-free with reader mode and export to epub
- block ads and trackers on a lightweight android browser
- run tampermonkey-style userscripts on mobile
- chat with or summarize web pages using an AI assistant
- turn pages with volume keys or screen taps while reading
- read CJK vertical text with custom fonts on android

## When to choose
- you use an Android e-ink device or e-reader and need a browser tuned for e-paper displays
- you want a small, fast, privacy-focused browser with ad blocking and per-site controls
- you need reader mode, EPUB/PDF export, or userscript support on mobile
- you want AI features (chat, summarize, TTS) integrated into your browsing

## When to avoid
- you need a full-featured mainstream browser with extension ecosystem like Firefox or Chrome
- you need desktop browsing - this is Android-only
- you rely on heavy web apps needing the latest engine features beyond WebView
- you need strict FOSS licensing assurance - the license is not a standard OSI-approved one
