Most study tools optimize for the answer. Type a question, get a response, move on. That's fine until the goal is actually learning something — because the part that builds understanding is the work in between, and that's exactly the part those tools skip.

Lune Synth™ is the opposite bet. Do the work by hand, scan it in, and get feedback on your reasoning — the steps, the missteps, and the specific place a proof or a derivation went sideways. We call it the anti-slop learning app because it grades the thing you actually did, not a clean answer you could have copied.

What we're building

The loop is simple on the surface and hard underneath:

• Do the work. Pencil and paper, whiteboard, tablet — however you think best.
• Scan it in. Handwriting, typed answers, or spoken explanations all count.
• Get feedback that helps. Rigorous, rubric-based grading that points at the exact step, not a vague score.
• Practice what's weak. Targeted missions and quizzes built from where you actually struggled.

It's built for the full range of learners — from the Pre-K through the PhD level — and it's designed to be honest about what you know instead of flattering about it.

What you'll read here

This blog is our working notebook. Expect posts on:

• Product updates and new features as the beta grows.
• The learning science behind why handwritten, self-generated work sticks.
• How we grade — rubrics, review, and the guardrails that keep feedback rigorous.
• Occasional field notes from teaching, testing, and getting things wrong.

The goal isn't to make studying feel easy. It's to make the effort count.
