Motusor is an independent software studio in Hong Kong. We build GrabScore, an AI IELTS writing feedback tool, and lucnook, a local-first task and notes app.
Every product gives you a few high-signal surfaces: score, next action, calendar, and exports you can inspect.
Band diagnosis with sentence-level revision and one next drill.
Live Products connected by the same studio standards.
Useful feedback that points to the next concrete move.
Readable exports, local-first posture, and data ownership by default.
Each one does a few things well: fewer menus, clearer next steps, faster feedback.
GrabScore scores one IELTS essay, then returns a band breakdown, sentence-level revision, and one focused drill for the next draft.

Motusor is the studio system behind GrabScore and lucnook: the same product principles show up as scoring, planning, ownership, and calm daily progress.
Each product finds the next useful signal inside messy work: a draft, a task list, or a folder of notes.
The screen should make the next move obvious.Capture, decide, act, review. Motusor tools are built for repeat use, not decorative dashboards.
Small actions should turn into visible progress.Feedback, plans, notes, and exports stay readable after the session ends.
Clear history, open formats, calm ownership.
