TutorOS
Interactive learning through guided lessons and feedback.
01The product
TutorOS is an interactive tutor for algebra, physics and geometry — “a more thoughtful way to learn.” Every answer is checked exactly, and hints arrive one step at a time rather than all at once.
Sessions move through three stages — Learn Together, Try It Yourself and Challenge Yourself — from being guided, to working a problem with support, to working it alone.
The design focus: make explanations clear, support learner confidence, and move learners from watching to actively solving problems.
02My role
Product design, learning-flow architecture, interaction design, frontend development and AI integration.
03Three stages
04Key decisions
- 01
One hint at a time.
Showing a full worked solution turns learning back into reading. Releasing one step per request keeps the learner doing the thinking, and keeps the screen calm.
- 02
Check answers exactly.
A tutor that is loosely right is worse than no tutor. Exact checking means feedback can be trusted, which matters most when someone is unsure of themselves.
- 03
Move from guidance to independence.
The three stages hand control to the learner gradually, so confident and hesitant learners both have somewhere to start.
05What I chose not to build
A tutor can be built to do almost anything on request. The design work was deciding what it shouldn't do.
- Why it was tempting
- Showing the whole solution is the fastest way to unstick someone, and it's what most learners ask for.
- Why I cut it
- Once the full answer is on screen, the learner stops thinking. One step per request keeps the work theirs.
- What got simpler
- The screen holds one idea at a time instead of a wall of working.
- The trade-off
- Someone who just wants the answer has to ask several times. That friction is deliberate.
- Why it was tempting
- Loose matching is easier to build and rarely tells anyone they're wrong.
- Why I cut it
- Feedback is only useful if it can be trusted — most of all for a learner who isn't sure of themselves.
- What got simpler
- Right means right. There's no “close enough” to interpret.
