Great! Suggestion

Love this so far! I have a suggestion (and I’m not creating a twitter account for that lol). I would love if my notes and everything would sync between devices. At home I like to study on the iPad, but otherwise I’m on my phone. I’d like to sync to where I left off.

Top tier

Came here from the online book and nothing cemented my knowledge of Japanese more than Tae Kim’s grammar Guide, even when using other methods the stuff from this Guide stuck and I find myself refering back to it

A free resource way better than any paid app I’ve seen.

I wish I knew where to find more honest and real material like this. It would save me a lot of time filtering through apps and websites begging for subscriptions to use it. I’m not far into the lessons but even just from the intro page I’m hooked.

Better than Genki

This is just absolutely incredible! Everything is well-organized, wonderfully explained, and even nice-looking. It helped clear up a lot of my confusion surrounding adjectives and adverbs (e.g. hayai vs. hayaku). Genki didn’t explain why the -i to -ku change happens. Now I know!

Bad Grammar

Has bad English grammar/typos in the content, so I don’t trust it to teach me Japanese grammar.
