Show HN: Open-source early-reading reader with phonics help

Yara Reads is an open-source early-reading app designed for children who have learned phonics sounds. It provides stories where every word can be sounded out, offering interactive help by tapping words to reveal sound buttons. The app checks stories word-by-word against known sounds, allows users to bring their own books via agents like Claude or ChatGPT, and enables parents to customize known sounds and tricky words. Built with Cloudflare Worker, D1, and R2, it's available for tech-savvy parents to run and customize.
