I'm working on a framework for general purpose interactive tutoring systems. An SRS background process over a pluggable system of pedagogy protocols over a given curriculum. This is at https://github.com/patched-network/vue-skuilder, or https://patched.network/skuilder

With this framework, I'm making (among other things) an early literacy app at https://letterspractice.com. My aim here is to hit >= 75% efficacy of Mentava at <= 1% of the price.

The app is near to production readiness, and I'd be happy to share access now with anyone who has verbal but non-literate kids. Be in touch if interested at colin at letterspractice.com
