A stuck moment, 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.

Start with one clue: follow where the energy enters the system before naming where it is stored.
How it works
From the real question to a reusable method.
Bring the real question
Type it, paste it, or add a homework photo so the explanation starts from the assignment in front of you.
Choose how you want help
Ask for an explanation, a hint, a check of your work, or a teach-back so you can prove you understand.
Prove the idea clicked
Run a 30-second check or turn the topic into flashcards, a quiz, a graph, or a homework mission.
A study sidekick, not an answer dump
Lirno is built for curious students who want to finish homework faster and still understand what they are doing. Lirno Tutor keeps the focus on reasoning: what the question is asking, which concept applies, and what to try next.
Use it when you are stuck on a single step, when a worksheet feels dense, or when you want a second explanation in clearer student language.

What makes help useful
The best sessions begin with the real question and a little context: your grade level, what you already tried, and where you got stuck. Vague prompts get vague help.
Treat every explanation as a learning aid. Double-check calculations, cite sources when your teacher requires them, and follow your school’s academic integrity rules.
From one question to lasting practice
A strong homework night does more than clear tonight’s worksheet. Save the topic, turn it into a study set, or continue in a mission so you can revisit the idea before a quiz or exam.
Lirno connects tutoring with planning and practice so help does not disappear the moment the assignment is submitted.
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.

Next: Scan homework
Take a photo or open a homework file. Lirno helps identify the tasks, confirm the subject and level, and turn the assignment into a guided Homework Mission.
