The thing is I keep track of absolutely everything Japanese related.
So I can’t settle with one site exclusively on the stats offered by learnnatively, bunpro, bookmeter, etc…
I have also integrated the tool into various things such as a Streamdeck and a Discord bot, and technically since you are in control, the possibilities are endless. You could even integrate it with the API of the websites and get the data automatically and things like that… but that might be outside of my knowledge scope.
I have recently come across a tool that helps that is open source that I have added to my report workflow, I’ll write about it soon in more detail as I finish tinkering with it along with the other changes I have made since the initial post. This tool is more designed towards software development but it works as well for other things such as Language learning tasks.
