I was just thinking including Anki as part of it. Ship with it. That's all. Not rebuild.

I'd probably focus less on the content recommendation. But I'm not seeing the big utility as specifically a language learning app. Unless it is purely about language learning content, not just youtube and netflix videos.

For ML, as an ML person I'm glad to hear you say this. I hate when it's hamfisted into bullshit things. The ideas you have seem good though but most are probably handled better by other products which you could integrate. But I am not aware of a good product that helps with pronunciation (at least to any passable degree), though I am aware of ones that do this for singing. I'd see this as a killer feature but it'll cost you some compute to get there.
