Penmentor
Pen your maths in Xournal++, press a key, get teacher-style ink marks back
For self-taught learners and homeschoolers, it turns your coding agent into a tutor that nudges with hints instead of handing over the answer.
Penmentor watches a Xournal++ page while you work through maths on a pen tablet. Press a key and Claude Code, Codex or the Antigravity CLI marks the page in coloured ink: a tick on correct lines, a circle on the first real error, underlines on steps that depend on it. Hints escalate from a nudge to naming the technique to a faint ghost of the next line, and it can render a manim animation of a boxed idea. Linux on X11 only for now; MIT licensed.
