This looks fine, but I legitimately have no interest in this if it isn't open-source. I know that sounds harsh, but I've gotten so tired of tools changing over time, slowly goading me into another subscription service that I desperately don't want.

I appreciate this tool being free at the moment (the world doesn't need another SAAS), but I've seen nothing on this page that really makes me want to use it. To me, I see a cloud-based Anki alternative with less control over your data/freedom.

Thanks for the feedback. Going open-source is something we'd consider but right now we're focused on building a tool that people love (which becomes difficult with a bunch of hobbyist developers contributing).

Also closed source isn't always bad. It's no secret that Duolingo has the world's best spaced-repetition algorithm - they will IPO for 2.4 billion soon.
