I'm building a reader app that tries to solve this exact problem by providing a range of gradually simplified versions of each article to match your proficiency. So you can stay in the sweet spot, or work your way up version by version.

If your target language happens to be Chinese then you can give it a try at https://reader.longyan.io/landing

Sure. This kind of project seems to be pretty common. I'd strongly suggest using traditional characters as a base because it's very easy to map multiple characters into simplified forms but much harder to disambiguate simplified forms into the traditional versions.

Thanks for having a look, I actually started out from traditional characters, but once I realized >90% of the students only do simplified I switched.

I also tend to believe to just convert between them is not the best approach. Better to find different content for both. If student wants to learn traditional script, they usualy want content from Taiwan and not from China, and the other way round.
