I think it is a solid method to learn a language by reading a lot and taking notes on words and expressions. I learned french this way in the past year and now I can read entry level texts including news sites like lemonde.fr. The method I was using is similar to what you described, but less automatic and integrated. To save dictionary time, I used the google translate extension, I configured it to pop up automatically when I select some words. It worked like a charm. I didn't have a good tool for review. But I usually read the article again to check if I remember the new words. Recently I came across lingonote.com, which seems targets the material collection and review problem as well. I myself is also building a language learning app, but more focused on listening and speaking. I am not reaching out for cofounder per se, but I am very happy to see your post and would like to offer my encouragement. I also checkout the Parsnip app the other day. nice try:)
