How would you explain a fraction?
Your words become an explanation
A fraction shows equal parts of a whole. If I share a pizza in four equal slices, one slice is one quarter.
You recalled the idea and gave it an example.

A little feedback.
A clearer explanation.
Find a gap, work on it, and try again. Use what you discover to guide your studying or give a weaker point its own review goal.
Retries and resumes are part of the same review.
Small changes. Clearer understanding.Example feedback
Your first attempt
“To simplify 6/8, divide the top and bottom by 2. That gives 3/4.”
A useful next step
Your method is right. Add why dividing both parts by the same factor keeps the value unchanged.

What can I study with RigorSync?
Anything you can define in words and numbers—from a historical event or scientific concept to a formula, language rule, or work process. Bring a clear explanation, course notes, a worked example, or your own writing as a starting point.
What happens during a review?
A review has four parts: explain aloud, answer a short quiz, teach the idea in your own words, and connect it to another idea. AI feedback helps you identify gaps and retry. You can skip speaking when you can’t talk.
Do I need a card to try it?
No. Create an account to get 10 free review starts. It’s a one-time allowance. Retrying or resuming a review you already started does not use another review. Paid subscriptions are coming soon.
Can I choose how challenging it is?
Yes. Explanation level changes how simply or technically things are explained. Review goal changes the depth of understanding you’re practicing. You can adjust both in Settings.
How should I use the AI feedback?
Use feedback to guide your studying and your next attempt. If it reveals a weaker part of a larger concept, create a focused review goal or a separate study idea to practice that part. Check the feedback against your learning materials, since AI can make mistakes. Scores are practice feedback, not a guarantee of mastery or exam performance.
Can I use it on my phone?
Yes. RigorSync works in your phone’s web browser as well as on a computer. Dedicated Android and iOS apps are part of the longer-term plan; they are not available yet.
