So I built this book reader app to allow her to click on the words, sound out the phonemes, and read by herself.
My 12 year old son wrote the first story, there's a cliffhanger at the end and he's working on the next section.
We're going to release more chapters and more stories in the near future.
And there's one other thing -
The reader has an MCP connection, so you can connect your Claude or ChatGPT or Grok, give them a PDF of a book you like (or even a set of scans done quickly with a phone camera) and have them import your favorite books into the app (private to your account, for your own kid, if you own the book of course).
The reader is free to use on its website and open source if you want to tinker and create your own version.
The included stories are under Creative Commons.
Jerry Pournelle often mentioned having an application which would teach reading --- apparently it is now out of print?

Have you looked at intermediary things such as the "Living Books"?
