Has anybody used cooori.com? It appeared as a google ad for me when searching about JLPT and looks similar to smartfm/iknow.jp

It claims to learn based on the user, which to me sounds like it is another SRS based site:

Quote:When a person starts using the Cooori system to learn Japanese our artificial intelligence engines start building a model of that persons studies and how they are progressing.

It seems to be iknow.jp with a few additional features (grammar points, etc.) I can't find any information on it from google -- nor on here -- so I guess it's new?

Had a quick look it is a flashcard site and has Genki, and Minna No Nihongo decks.

So I guess no-one here has used Cooori?

No, these kind of services seem like a waste of money to me. SRSs are free. If there aren't vocab/grammar lists or decks that suit you, it's fun to make your own as you go anyway.

Yeah, I wouldn't pay for something that I've essentially already got. Putting in the work will net you progress; buying new shinies, in itself, won't.
