How it works
From a stuck problem to a reusable method.
Capture the full question
Type the problem or scan the worksheet with diagrams, units, and instructions visible.
Ask for the help style you need
Choose a hint, a first step, a full explanation, or a check of the work you already tried.
Practice so it sticks
Turn the method into a mission, quiz, or flashcards before the next class or exam.
Choose by goal
Pick the math workflow you need tonight.
Get unstuck fast
Hints, first steps, concept labelsAsk for a hint or the first setup before requesting a full walkthrough.
Check your own work
Error spotting, reasonableness checksPaste your attempt and ask where the reasoning broke—not only what the final number should be.
Scan a worksheet
Photos, PDFs, textbook pagesCapture the full problem with diagrams and units, then confirm what Lirno read.
Practice the method
Flashcards, quizzes, missionsConvert tonight’s solved item into practice so quiz day does not feel brand new.
Prepare for exams
Weak-topic inventory, timed checksPrioritize shaky skills and run short quizzes without looking at the chat history.
Stay organized
Homework inbox, due dates, focusKeep math assignments visible beside tutoring and practice instead of scattered notes.
Speak the method
Six math terms that make AI help more useful.
Setup
The equations, diagram labels, or relationships you write before calculating.
Ask whether your setup matches what the question is asking.Isolate
Rearranging an equation to get the unknown alone on one side.
Ask which operation should come first and why.Units
The measurement labels that keep answers meaningful and catch impossible results.
Confirm the units the teacher expects in the final answer.Estimate
A quick reasonableness check before or after computing the exact result.
Ask whether the magnitude of the answer makes sense.Similar problem
A practice item that uses the same method with different numbers.
Request one similar problem after you understand the original.Teach-back
Explaining the method in your own words to prove you can reuse it.
Ask Lirno to quiz you on the method without showing the solution.Match help to your level
Tell Lirno where you are in school.
Adding your level and what you already tried produces clearer tutoring. The goal is a method you can reuse—not a one-night copy of the answer.
Middle school
Focus on clean setups, fraction fluency, and reading word problems carefully before calculating.
High school algebra
Prioritize method choice, isolating variables, and checking signs across multi-step work.
Geometry
Keep diagrams labeled, confirm given vs. unknown, and scan figures clearly when using photos.
Pre-calculus / calculus prep
Name the concept first, then walk the procedure. Practice until you can start without the chat history.
Exam crunch
Inventory weak topics, run short timed checks, and rebuild study sets from recent mistakes.
Plan the practice
A solved problem should become a reusable skill.
Same-night review
5–10 minutesOne similar problem or a few flashcards while the method is fresh.
Quiz prep block
20–30 minutesMix shaky topics with a short no-notes check.
Weekly catch-up
1–2 focus sessionsReopen missions from units that still feel unstable.
Exam week
Daily short blocksPrefer dense practice over one impossible marathon.
After a wrong answer
ImmediateIdentify the broken step, then practice that skill once more.
Start with a better scan
The photo controls how useful the explanation becomes.
Sharp focus, even light, and the full problem—including diagrams—give Lirno a cleaner starting point.
