User reviews

With all the buzz about learning by immersion, Hayailearn provides an excellent learning environment currently based on the many Youtube Japanese videos at all levels of difficulty. It leverages spaced repetitition to help you learn new words and best of all, provides an AI explanation of the vocabulary and grammar of the part of the video that you are currently watching. There are many other features and the developer Lawrence Tan, is actively enhancing the platform and is very responsive to user questions and suggestions. There's also a Hayailearn community on Discord. After a free trial during which I had several questions that were quickly answered, I was happy to invest in the lifetime package. This may be one to buy into now as the price is sure to go up as he adds more and more!

This requires a paid ($10/month) account but they do give a free trial. I spent a lot of time with DuoLingo, using Anki flash cards, and books, but listening to Japanese videos while getting the explanation I needed to understand was even better than on-the-street immersion for me. Just wish it was free...

One of the best learning tools I've ever tried (and I tried them all). The developer is very responsive and actively implements requests.
