Language learner looking to build tool

Hi everyone!

I’m looking to validate an idea I’ve been exploring. I’ve been learning Brazilian Portuguese for the past six years and would say I’m around a B1/B2 level. I meet with a tutor weekly and keep both a handwritten notebook and a Notion doc for my homework, but sometimes struggle with my writing.

I’ve been thinking about a platform that could help nudge me in the right direction with my writing. Something that explains why one phrase might work better than another, tracks my progress, and helps me avoid anglicized sentence structures. In an open-ended notebook style.

Does this sound like a useful way to supplement language learning? Would you use something like this?
