EinkBro

EinkBro is Daniel Kao’s browser for E-Ink readers and note tablets. It began as a fork of FOSS Browser, but now has its own reading, export, translation and userscript features. The interface avoids unnecessary transitions and uses clear black-and-white controls that remain legible after an E-Ink refresh.

Reading tools

• Tap the screen edges or use volume buttons to move by a page instead of smoothly scrolling.
• Reader mode extracts an article, with custom fonts, size and bold controls; vertical layout supports CJK reading.
• Turn a web page into an EPUB, append pages to one book, save PDF with a table of contents, archive MHT, or capture a full-page screenshot.
• Split two pages on screen, put the toolbar on an edge, assign more than forty toolbar actions, and keep per-site settings for images, JavaScript, CSS, desktop mode and dark mode.
• A built-in blocker uses filter lists, while URL cleaning removes common campaign parameters.
• A Tampermonkey-style userscript engine implements GM APIs, matching rules, menu commands and updates.

The browser can send a page to Instapaper and integrates with Android dictionaries and text-to-speech. Its optional AI panel can chat with or summarize the current page, translate paragraph by paragraph, and work with OpenAI, Gemini or an OpenAI-compatible server such as Ollama. Those actions send the selected page text or media to the provider you configure; they are not local just because the browser itself is open source.

Version 16.7.1 adds optional Jev smart extraction through TypeSafe’s API, keeps original pages reachable after popups, fixes stale tabs and dictionary translation, and avoids a crash when a custom font document is missing. Smart reader is off until you enable it, and Jev extraction also needs a key.

Permissions and network behavior

The measured APK declares 13 permissions. Internet and network state are fundamental to a browser. When you grant Android location access to EinkBro, its WebView grants subsequent website geolocation requests without a separate per-site prompt; website microphone requests are also granted by the WebView. Storage permissions cover old Android releases, notifications report downloads, and the F-Droid build can hand a downloaded APK to Android’s package installer.

Our scan found no tracker SDK. That does not mean browsing is anonymous: websites receive normal WebView traffic, and search, translation, AI, TTS, Instapaper or filter-list updates contact the provider selected for that feature. Adding an OpenAI key makes OpenAI the default text-to-speech engine; Google Drive backup can upload every selected backup category, including AI settings and keys. The app permits plain HTTP as well as HTTPS because it is a browser.
