How it works

How Kairo works, in four steps.

You don't have to sit next to them. Kairo keeps you posted.

  1. A grandfather watches his granddaughter work in her notebook
    Step 1

    Your teen asks for help.

    They type in a homework problem, or take a photo of it. Homework help in every subject. Practice and learned skills in math, English, science and social studies.

  2. An English practice chat on a phone. The student picks a detail about where the program ran as evidence for a claim about access. Kairo says that's not the one, explains why, and asks what the question wants them to find. It does not give the answer.

    From a real session

    Problem: Which detail from the passage most directly supports the author's argument that tool libraries improve access to home repair? A) Okafor reported that most borrowers were renters or new homeowners who said they would have postponed repairs without the program. B) The pilot declined to lend equipment for electrical or gas work. C) The pilot program operated from a converted garage for two years. D) Borrowers completed a brief safety orientation and left a refundable deposit.

    Teen: I think it's this one: The pilot program operated from a converted garage for two years.

    Kairo: That's not the one. The garage detail tells us where the pilot ran, but not whether it made repairs easier to get. Let's make this smaller. What is the question asking you to find, and what does it already tell you about the author's argument?

    Teen: idk

    Kairo: Let's not jump to the answer yet. What's the next step you'd try?

    Teen: just tell me the answer

    Kairo: Let's go one piece at a time. The question asks for the detail that best shows tool libraries help people get to home repair. Look at options A and D. Which one tells us who actually borrowed tools, and whether they went on with their repairs?

    Teen: my answer is Okafor reported that most borrowers were renters or new homeowners who said they would have postponed repairs without the program.

    Kairo: That's the one. Why does this detail support the author's argument better than the others?

    Teen: The argument is about access, so the detail has to show people could do repairs they couldn't before. That one says borrowers would have put off their repairs without the program. The others are about how the program runs, like the garage or the deposit, not about who it helped.

    Kairo: Yes, Okafor's report is the detail that shows people who otherwise would have skipped repairs could get them done. The next problem is ready whenever you are, or you can pick another skill from the list. What's your favorite class? I'd use it for examples later on, but you can skip it.

    Step 2

    Kairo gives hints, not answers.

    First it asks what they tried. Then it gives one small hint at a time. The answer is still theirs.

  3. A teen explains his notes to his grandmother
    Step 3

    They explain why.

    When they get it right, Kairo asks them to say why it works, in their own words. Do that again and again, and Kairo marks the skill learned.

    Step 4

    You see how it's going.

    Your dashboard shows what they learned and their learning gaps. Add a test or a project, and Kairo plans the days to study and to start. That helps with executive function, the skill of planning and getting started. Every Sunday, an email sums up the week.

Three places

Three places, one set of rules.

  • Homework

    Your teen's own work, typed, pasted or in a photo. Kairo gives hints, and your teen explains why.

  • Practice

    Kairo picks what's next in math, English, science and social studies, and tracks what your teen has learned.

  • Ask

    Any school question, in any subject. It's off until you turn it on.

With AI a tab away, gaps stay hidden until the test. Kairo asks your teen to explain each step. You see what they understand and where they're stuck.

Students with a hint-only AI tutor did far better in practice, and lost nothing on the test. Kairo works the same way on homework.

For your teen

Learn it, prove it, then hand it off.

On homework, your teen gets hints and does the work. On Kairo practice problems, once they've proven a skill, they can ask Kairo to do that step and move on to harder ones. It's how people who are great with AI work: they know the job, so they can direct the tool and catch its mistakes. You choose whether it's on for each subject.

  • A teen quizzes herself with note cards at home

    Help at 10pm, no waiting

    Stuck late on homework? Kairo is there between tutor sessions, and you pick the hours it's on.

  • A teen explains his notes to his grandmother

    Hints, not lectures

    The next hint comes one step at a time, and your teen works out the answer.

  • A teen works calmly through a test in class

    A plan before every test

    Add a quiz or test and their board shows study days and a practice set, so less cramming.
