Notes from the anti-slop lab
Product updates, learning science, and behind-the-scenes on how we turn handwritten reasoning into checkable work, rigorous grading, and targeted practice.

Friction is where learning starts
The resistance you feel when you retrieve, struggle, and try again is not getting in the way of learning. It is often the part that changes you.

AI is quietly breaking how we learn
There are two ways to use AI in school: one is cheating, the other feels like studying and mostly isn't. A blunt look at what's actually happening — and why Lune Synth is built to do the opposite.

Welcome to the Lune Synth blog
Why we're building a learning app that grades the work you actually did — by hand — and what you can expect to read here.
