Plug for our https://uphop.ai/app : it's for adult learning / corporate training. We break down a desired job skill into small chunks, and engage the user with practice & give nuanced feedback. And of course like chatbots make it easy for user to ask more questions or go on tangents.

Would appreciate feedback!

There's a bit of overlap with Learn Your Way I guess. I'm not sure users need to toggle between alternate formats of the same instruction though. Instead the instruction itself should be as multi-modal as possible, and offer flexibility to ask questions... which even gemini.google.com offers so I'm not sure this is a net improvement over that.
