How LessonOrca works

It notices how you work.
It connects that to what it knows about you.
Then it decides what comes next, and tells you why.

  • SAT
  • PSAT
  • ACT
  • AP
  • Subject tutoring

Orca, your AI tutor, teaches every lesson.
The examples follow Nora, who is studying for the SAT.

01

A curriculum that rewrites itself

After every session, it checks how you did and rewrites what comes next.

Example: Nora gives her goal score, her SAT date, a first quiz, her soccer days and how she likes to learn. The engine builds her plan from her weakest skills, with short sessions on soccer days and long ones on Sunday. After session 3, she says that transitions feel random, so the engine changes session 5 to a teach-back on transitions, and her coach checks the change.

One turn of the loop

Every quiz, lesson and homework set goes through these five steps.

Example: you get 4 of 9 quiz questions correct, and Orca finds that you misread 4 of them. Your coach checks the plan change, so your next session starts with 5 read-the-question drills.

  1. You do a quiz.

  2. Orca finds the cause.

  3. The planner proposes a change.

  4. Your coach checks it.

  5. Your next session changes.

  • It rewrites your plan after every session.
  • It also changes how your AI agents work with you.
  • Your coach checks your plan.

Your own team of AI agents

Four AI agents work only for you, and each one has one job.

Nora’s four AI agents all read her profile. Each agent uses a different note from it.

Nora’s profile

  1. Note 1Learns best by drawing and explaining it back.
  2. Note 2Soccer on Tuesday and Thursday.
  3. Note 3Said, “Transitions feel random.”
  4. Note 4Stops at x when the question asks for x + 2.

All four agents read it

Orca, your AI tutor

Draws each idea first, then asks her to explain it back.

Uses note 1

AI planner

Puts 20-minute sessions on soccer days and 60 minutes on Sunday.

Uses note 2

AI quiz maker

Puts more transitions questions in her next quiz.

Uses note 3

AI homework maker

Makes 6 new “what does it ask for?” questions for her.

Uses note 4

After each session, the notes change, and the agents change with them.

  • Every agent reads the same profile of you.
  • So your lessons, quizzes and homework all aim at the same gaps.
  • After each session, LessonOrca updates your agents.

The engine behind your agents

  • Your inner harness is your own AI agents, your plan and your lesson formats.
  • Your work goes into the context, the memory of what you know.
  • The strategy model reads that memory and proposes a change.
  • Your coach checks your plan.
  • Every change moves you toward your goal.
An abstract diagram of the engine. The student's work flows into the inner harness and into its memory. The strategy model in the outer harness reads that memory and proposes a change. A coach checks the change, and the inner harness then changes its shape, always toward the goal.

A living profile of you

It reads your work, your words and your week, then builds your plan around all of it.

An example of how the engine reads one student, Nora. From her quiz results, her own words and her calendar, it finds that she misreads questions under time pressure, that she learns best when she draws and explains, and that school nights are short for her. So her plan starts each set with a reading drill, uses whiteboard and teach-back lessons, and puts short sessions on Tuesday and Thursday and a long one on Sunday. Her coach checks these changes.
  • It does not follow a fixed list of rules.
  • It finds the reason behind what you do.
  • Your plan, Orca and your practice all use what it learns about you.

04

A plan that runs to test day

Every skill, every session and every goal, mapped to where you are right now.

Example study plan for a student: sessions 1 to 3 are done, and session 4 today, a Sunday, has a 60-minute plan with two goals. Sessions are 20 minutes on her soccer days and 60 minutes on Sunday. The plan says why: she rushes when timed, so the warm-up is a reading drill, and she learns by drawing, so vertex form is on the whiteboard. A second panel shows her level in four SAT skill areas, and what the engine knows about her: how she learns, her soccer and work days, and that her focus drops after 25 minutes.

Miss it today. See a different plan tomorrow.

  • Each change has a reason.
  • Your coach checks your plan.
Example plan update after a session: Advanced Math went from Needs understanding to Still learning, because the student had 5 of 6 correct. She explained vertex form out loud with no help, so more lessons will be teach-back. She has a late game on Thursday, so session 6 moves to Wednesday. Her coach checked the changes and signed them with the initials J.R.
  • It counts the weeks to your test day.
  • Your weakest skills come first.
  • Each part of each session has a reason you can read.
  • When something changes, the later sessions change too.

Real experts correct the AI

The AI suggests, your coach can change it, and we save the correction.

The AI planner suggests a transitions drill. Nora’s coach, J.R., changes it to an explain-it-back lesson. We save the correction.

  1. 1The AI planner suggests

    Add a transitions drill on Tuesday.

    Because she got 4 of 9 transitions right on Sunday.

  2. 2Her coach, J.R., changes it

    Transitions drill

    Make it “explain it back.”
    She knows the words.
    She needs to say why they fit.
    J.R.

  3. 3Nora gets

    Tue, 20 min · Transitions: explain it back

    We save the correction.

  • The AI makes the first plan.
  • Your coach checks your plan and can change it.
  • We save each correction.
    With your OK, we plan to use saved corrections to make LessonOrca better.

Orca teaches. It doesn’t tell.

Orca works through every lesson in your plan with you, on a whiteboard.

Example AI lesson: Orca, the AI tutor, circles the error r = 5 on the student's whiteboard. The student writes r = 0.05, and a notice says that the study plan changed.

Three more ways to work with Orca

  • Talk to Orca.

    Orca listens and asks you to explain each step.

    Example screen: Orca asks, “Why is the power 3?” Orca listens, and shows what the student said: “it is 3 years.”

  • Send a photo of your paper.

    Orca reads your work and asks you about each step.

    Example screen: a photo of the student’s paper with four lines of work. Orca draws a circle around the line A = 1000 (1.08)³ and writes, “Good. Why the 3?”

  • Teach it back.

    You make a short slide, and Orca checks what you understand.

    Example screen: the student’s slide shows $100 times 1.05 equals $105, and a bar split into “100% you keep” and “+5%”. Orca writes, “Which part is the money you keep?”
  • Orca does not just give you the answer.
  • It asks about each step, and it listens to your reasons.
  • It notices what went wrong, and your next session changes.

Same question. Different mistake.

Orca reads each step of your work, so your next session works on the cause.

Same wrong answer. Different reason.

  • Nora and Leo miss the same question.
  • Orca reads each step of their work.
  • So each next session fixes a different cause, not only the answer.
Two example students miss the same question: if 3 times the quantity x minus 4 equals 18, what is x plus 2? The correct answer is 12. Nora answered 10 because she stopped at x, so her next session is a reading drill. Leo answered 4 because he subtracted 12 when he had to add it, so his next session is a lesson on inverse operations.

Same test. Same goal. Different plans.

Because you are not Leo, and Leo is not you.

Two example students, Nora and Leo, take the same SAT with the same goal of 1400. Nora is weakest in Advanced Math and Leo is weakest in Algebra, so each plan starts with a different skill and uses different lesson formats.

+1 transitions session before the test.

Orca, your AI tutor

  • Teaches every lesson.
  • Helps when you are stuck on a question.

Your coach

  • Checks your plan.
  • Answers your messages.
  • Does not teach lessons.
  • Your coach checks your plan.

It fits your week

Busy days get short sessions, and free days get long ones.

Nora has soccer on Tuesday and Thursday and works on Saturday. She gets 20-minute sessions on soccer days and 60 minutes on Sunday. She tells Orca about a late game on Thursday, so her Thursday session, Quadratics part 1, moves to Wednesday, at 15 minutes.

What it knows about Nora’s week

  • Soccer on Tue and Thu
  • Works on Saturday
  • Sunday is free
  • Focus drops after about 25 minutes
  1. Mon

  7. Sun60 minQuadratics, part 2 and transitions

I have a late game on Thursday.

That session moves to Wednesday, at 15 minutes.
Sunday stays long, because it is her free day.

  • Tell it about your week once.
  • Short sessions go on busy days, and long ones go on free days.
  • If your plans change, tell Orca, and your session moves.
