CrossPoint Reader

CrossPoint is community-built, open-source firmware for e-ink readers based on ESP32 chips, including devices like Xteink X4, reTerminal Sticky, and M5Paper. It prioritizes reading experience with proper typography, hyphenation, footnote links, and customizable fonts. The project was built using Claude AI coding tools according to repository documentation.

The software offers comprehensive library management with indexed search across titles and authors, wireless file transfer via WiFi and web UI, OPDS browser support, and Calibre integration. Users can customize fonts, themes, languages (34 UI languages supported), and reading modes including focus reading. It handles multiple formats natively and supports right-to-left text and CJK scripts.
