https://readini.com Side by side, synchronized audio, dictionary, learning words. I'm the author. Considering coming back to working on this project, with more books and languages.
Wonderful! Thanks for sharing and hope you find time to expand on this project. Good luck!
I am interested in English-French at the moment and was hoping to use sideloaded ebooks and mp3 audiobook versions - not necessarily just old classics out of copyright.
It seems there are some open source projects that replicate Amazon Whispersync (sync audio to text and highlight words/phrases as they are spoken).
Thank you. It gives me some motivation :)
