The Neuro-Symbolic Engine

Lune Synth™ is built on a unique Neuro-Symbolic AI architecture designed to move beyond "vibes" and statistical guesses.

Rubric-Grounded Scoring

The system reads handwritten work, maps each step to explicit rubric rules, and keeps interpretation separate from scoring so feedback has a clear basis.

Designed to Reduce Grading Slop

Instead of relying on plausible guesses, the grading flow checks work against defined criteria. Mistakes are surfaced with supporting evidence, with review paths when a closer look is needed.

Explicit Rules, Not Vibes

Students get step-level feedback grounded in visible reasoning, so they can understand what to fix next.

Delivery Model

Think on Paper

Students do the work first, then use AI to sharpen it.

Read the Work

Vision turns handwritten reasoning into clean, checkable steps.

Grade the Reasoning

Each step is checked for correctness, not vibes.

Practice What Matters

Targeted drills, streaks, and progress loops keep students moving.
