700,000 Students, 148 Courses in One Year β€” How AI Is Reshaping Learning

Research suggests that a good personal tutor can improve a student's performance by more than two standard deviations compared to classroom instruction. The problem has always been cost β€” personal tutors are a privilege of the few. But what if an AI tutor could be provided to every student for about $24 a year? In 2026, that question is getting closer to an answer.

1. Khan Academy: From 40,000 to 700,000

Between the 2024–25 and 2025–26 school years, the number of users of Khanmigo β€” Khan Academy's AI tutoring service β€” jumped from 40,000 to 700,000. That's more than 17x growth in a single year. Partner school districts expanded from 45 to more than 380.

What makes these numbers compelling isn't just the growth rate β€” it's the learning outcome data behind it:

  • In pilot school districts, students saw an average improvement of 1.4 grade levels in math
  • Khan Academy achieves double the learning effect in less than half the time compared to other personalized learning software
  • Cost: approximately $24 per student per year

Khanmigo isn't designed to hand out answers. It works more like a Socratic tutor β€” asking questions to guide students toward their own understanding. "What have you tried so far on this problem?" "Why do you think that's the right approach?" These prompts keep the thinking where it belongs: with the student.

The US Department of Education granted $7.6 million to Georgia State University to scale this approach into introductory English and math courses β€” a pilot that could inform national expansion depending on the results.

2. Duolingo: Building 12 Years of Courses in One Year

In April 2025, Duolingo launched 148 new language courses built with generative AI β€” effectively doubling its total course library in a single year. It took the company 12 years to build its first 100 courses. The next 148 took about one year.

The new courses cover the 7 most popular non-English languages (Spanish, French, German, Italian, Japanese, Korean, Mandarin) across all 28 supported interface languages β€” unlocking combinations that previously weren't available at all.

The business results are striking:

  • Quarterly revenue hit $252.3 million (up 41% year-over-year)
  • Paid subscribers reached 10.9 million (up 37% year-over-year)

Duolingo's internal research suggests that 150 hours on the platform is equivalent to four semesters of university Spanish β€” though this is self-reported and awaits independent validation. What's clear is that AI dramatically lowered the cost of creating high-quality language content.

The expansion came with controversy, however. Duolingo also announced plans to replace some human contractors with AI, raising questions about what happens to the language specialists who built the foundation. Technology enabling more access while displacing the people who made it β€” a familiar tension.

3. VR Education: Learning Through Your Body

Where Khan Academy and Duolingo operate in text and audio, virtual reality (VR) education engages a completely different set of senses.

Research consistently shows:

  • VR learners feel 3.75 times more emotionally connected to content than they do in a regular classroom
  • Immersive learning improves knowledge confidence by 275% compared to classroom instruction
  • 93% of teachers believe VR would be beneficial in their teaching

The market reflects this potential. The global VR in education market is projected to grow from 24.24billionin2026to24.24 billion in 2026 to 83.09 billion by 2034 (CAGR of 16.6%). The share of US K-12 schools incorporating AR/VR in some capacity has grown from under 20% in 2022 to over 40% in 2026.

Walking through ancient Rome in a history class. Exploring the interior of a cell in biology. These experiences deliver something textbooks simply cannot. Cost and hardware access remain real barriers, but headset prices continue to fall.

4. What the Market Numbers Are Saying

Taken together, the numbers point to a genuine inflection point in EdTech:

  • Global AI in education market: 5.88billionin2024βˆ—βˆ—β†’projectedβˆ—βˆ—5.88 billion in 2024** β†’ projected **32.27 billion by 2030 (CAGR 31.2%)
  • AI tutors market: $3.55 billion in 2025
  • Active AI education startups in 2026: 2,800+ (an 18x increase from 2023)
  • Share of higher education institutions expected to deploy adaptive learning platforms by 2026: 71% (up from 34% in 2023)

These numbers don't just describe a financial trend. They signal a structural shift in how education is delivered. The 20th century model was "the same content, at the same pace, for all students." What EdTech is moving toward is "different content, at each student's pace, for each individual student."

5. Why Technology Isn't Everything

That said, important questions remain. As the OECD noted in its performance-learning gap research, AI tutors may raise test scores without deepening real thinking. Getting to an answer faster and thinking more deeply are different things.

There is also the equity question. Even a $24/year AI tutor is useless to a student without reliable internet access. The faster EdTech advances, the wider the gap grows for students who can't access it.

Technology is a tool. Good education starts with good tools β€” but it doesn't end there. A teacher's judgment, the relationship between teacher and student, the context of learning β€” these are things AI cannot yet replace. As technology races forward, remembering why we learn matters just as much as how fast we can learn.
