This $40M AI Company Is Using AI Tutors to Teach 2 Hours/Day | #233

The AI generates lessons based on knowledge graph, interest graph, and cognitive load theory, keeping accuracy at 80-85%. It uses vision models to coach learning habits. The system is mastery-based, so students don't move on until they master a topic. This frees up afternoons for life skills. The platform is called Timeback, and they've invested over $100M in it.

The vision models detect anti-patterns like switching to ChatGPT or Minecraft, guessing, skipping explanations. It assigns XP (experience points) only for focused learning minutes. A waste meter shows percentage of time wasted. This was initially trained with human reviewers watching recordings at night.

The system is called Timeback because it gives time back. It tells a student 'you're 17 hours away' from mastering a grade level. This reframes academic struggle as a time investment, not a lack of intelligence. It also allows advanced students to accelerate without being held back. Joe shared that when they assessed incoming students, A students were anywhere from 1 year ahead to 3 years behind; B students were 3 to 7 years behind. The system quickly fills those gaps.

The guide's role is purely motivational and emotional. These meetings are a key part of the culture. The most popular emporium item is a special lunch with the guide, indicating the value students place on this connection. The guide training is based on Dr. Yeager's '10 to 25' book and mentor mindset.

Examples include fifth graders running food trucks, high schoolers building businesses, a senior producing a Broadway musical, and a student submitting to Nature. The school also does an Ikigai values workshop and a 168-hour time tracking exercise to help students become intentional creators rather than passive consumers. The workshops are designed to be fun and team-based.

These micro-celebrations are part of the motivational culture. The silent dance party is a quick, fun break. The roller coaster involves the whole class. Alpha currency can be used to buy LEGO sets, snacks, or a special lunch with the guide. This system gamifies learning and reinforces goal-setting.

McKenzie says they host info sessions and shadow days. The warning is serious: kids will rebel if they have to return to traditional school. This is a testament to the love of school.

Joe mentions that they had Matt Ridley visit, and students used his own arguments to challenge his education doomerism. The school emphasizes that this is the best time in history to be a five-year-old because AI will give kids superpowers. The guides are also happy and optimistic, which contrasts with many traditional educators.

Joe explains that once a school has 100 students, demand surges. Founding families are crucial. McKenzie's own story of co-founding to curate her kids' peer group exemplifies this.

The waste meter is part of the AI coaching. It ties into the motivation of getting time back: if you waste time, you take longer to finish academics and have less time for fun workshops. The AI detects specific anti-patterns.

Joe explains that they took all the learning science and built an engine with AI tutors (not chatbots) that generate personalized lessons for each kid at their level, considering knowledge graph, interest graph, and cognitive load theory. The AI ensures 80-85% accuracy to keep kids in the zone of proximal development. They use vision models to monitor screen activity and coach learning habits, detecting cheating or guessing. They have a 'waste meter' showing time wasted. The system is mastery-based: students don't advance until they master a topic, so all kids can get 100% on standardized tests. This shifts the mindset from 'I'm not smart enough' to 'I'm 5 hours away from mastering it.' The platform cost over $100M to build, and they currently spend $10k per kid on AI tokens, which they aim to reduce.

The afternoon workshops are team-based, fun, and run by adults. Examples: fifth graders running food trucks and Airbnbs, high schoolers building businesses, a senior producing a Broadway musical, a student submitting research to Nature. The workshops are designed to be adaptable; for instance, a sailing workshop teaches adaptability and teamwork by sailing from Florida to the Bahamas. The school also has an 'emporium' where kids spend Alpha currency earned from hitting goals, teaching financial literacy. The guides help students shift from being consumers to creators, e.g., instead of playing video games, they learn to code and build their own. They do an Ikigai values workshop and track 168 hours of their week to become intentional.

Joe explains that they are the only ones with a closed-loop data cycle in education. The learning science team comes up with an idea, puts it into the lesson generation, kids do the lessons, and they measure learning via standardized test results. They can then adapt. He gave an example: in August, he announced a new math curriculum that would be 20% more efficient. Eight weeks later, he reported that grades 4-12 were exceeding targets, but K-3 were struggling because they gave too much freedom of choice; they adjusted and got back on track. This rapid iteration is possible because they control the whole stack. They initially had humans reviewing video to train the AI, similar to Tesla's autopilot training.

Joe describes the brainlift as a data structure for human knowledge. It categorizes areas where LLMs excel and where humans still have an edge, and they teach students accordingly. As AI improves, they update the brainlift. This prepares students to use AI as a superpower. The students are optimistic, telling Joe that AI will give them superpowers and 'it's wraps for you adults.' The school fosters this optimism by having students read 'The Rational Optimist' and 'Abundance,' and even had Matt Ridley visit, where students used his own arguments to counter his education doomerism.

Joe explains that nobody wants to be the first 20 families. Once a school has 100 students, everyone wants to come. So they find founding families who are willing to be first and actively recruit others. The two things parents need to move their kid: a reference from a trusted adult in their city, and seeing a kid at the school do something their kid can't (love of school, academics, life skills). McKenzie's own story: she co-founded Alpha to surround her kids with the right peers. Joe was a laggard, taking 2 years to be convinced.
