See it in a study session
A repeated mistake, turned into a clear next move.
Lirno starts from the work the student already has and makes the next useful action visible. The goal is not more output. It is a smaller decision, a meaningful attempt, and something worth remembering.

Save the earliest broken step, attach a correction rule, and schedule one similar problem.
How it works
From the real question to a reusable method.
Notice what broke
Save the mistake, confusing step, or weak topic instead of letting it disappear after the assignment.
Revisit the idea
Ask for a clearer explanation, practice a similar problem, or review the related study set.
Choose the next focus
Use subject patterns and progress views to decide where the next study block will matter most.
A Mistake Book you will actually reopen
A wrong answer is useful only if you can name what went wrong. The Mistake Book keeps important misses visible so you can return with Tutor, a similar problem, or a short quiz.
Save mistakes that reveal a pattern: the same sign error, a definition you keep mixing up, or a writing structure that repeatedly loses the main point.
- Save the topic and the broken step
- Reconnect mistakes to tutoring and practice
- Review before quizzes and exams
- Keep one error from becoming a repeated habit
See patterns across subjects
The Knowledge Map and progress views help turn isolated sessions into a clearer picture of what you have studied and what still needs attention.
Use those patterns as a prompt for the next action—not as a grade. A quiet week, a difficult unit, or missing data can change what the progress view shows.
Progress should lead to a decision
The useful question is not whether every chart moved up. It is what to do next: repeat a weak card set, start a focus session, reopen a mission, or ask for another explanation.
Rewards and streaks can make consistency visible, but rest, teacher feedback, and realistic planning still matter more than maintaining a perfect number.
Set the right expectation
Lirno is a learning companion. AI explanations can be wrong or use a different method from your class, so verify important steps, follow school rules, and keep the thinking yours.

Questions, answered
What should I save in the Mistake Book?
Save errors that reveal a reusable lesson: a misunderstood concept, a broken setup, or a pattern you are likely to repeat.
Is the Knowledge Map a grade?
No. It is a study view based on your activity and saved learning context, not an official assessment of school performance.
Can I practice directly from a mistake?
Use the saved topic to ask Tutor for a clearer explanation, create a similar problem, or return to related flashcards and quizzes.
Do streaks measure real understanding?
No. Streaks show consistency, not mastery. Use practice and teach-back checks to judge whether you can reuse the method.
