As an avid language learner I'm trying to create the best tool for intermediate to advanced learners, so for those who know that there is no silver bullet and learning takes years of effort, instead of some magical hack that AI-bros are trying to sell you.
https://okuread.com/ is a desktop App that works completely offline and helps you read foreign language texts and learn vocabulary that way. No AI-garbage included.
Right now I'm working on an open source platform for enabling human pronunciations in Oku. Anki/Flashcard integration and a UI redesign are also all scheduled sometime in Q2.
