Learn to adapt to anything.

The world changes fast. AdaptSage finds the exact mistake behind a wrong answer, then keeps working on it until it's fixed.

We started with one test that decides which high school a New York City kid gets into. What we built for it, an engine that names the reasoning error behind every wrong answer , works for whatever you need to learn next.

A detected pattern: the student misreads 'less than' as subtraction in 8 of the last 12 sessions

It finds the pattern

"Misreads 'less than' as subtraction, 8 of the last 12 sessions" is something you can fix. "Weak at algebra" isn't.

Quiet, focused practice

Nothing flashy. The SHSAT is stressful enough, so the app stays calm.

Full-length mock: 100 questions in 180 minutes, split across revising, reading and math

Full-length mocks

Timed like the real test and scored against all eight specialized high schools.

Student progress: predicted score rising from 527 to 553

One set of numbers

Students, parents and tutors all look at the same progress, so nobody has to ask how it's going.

"Our practice is adaptive, and it names the reasoning error behind each wrong answer."

That's the engine: an item bank, a difficulty model, an error taxonomy and a mistake journal. It works for any exam and it doesn't expire. It's the thing AdaptSage actually owns.

The SHSAT is the first. It won't be the last.

Any subject where reasoning can be checked can run on the engine. These are the areas we're looking at next.

Hi, we're AdaptSage.

We're a small team in New York City. We started by helping students prepare for one high-stakes exam, and found that more practice wasn't what helped. Finding the exact mistake and fixing it was.

Exams and careers change. You'll always need to find what you've misunderstood and fix it. That's what we build for.

Questions

How are AdaptSage and AdaptSHSAT related?

AdaptSage is the company and the engine. AdaptSHSAT is our first product, built on that engine for the NYC Specialized High Schools Admissions Test. Students and parents can sign up at adaptshsat.com.

Is AdaptSage only for test prep?

No. Test prep is where we started because the stakes are high and results are easy to measure. The engine works for any subject where reasoning can be checked, including other exams, certifications and job skills.

How is this different from other adaptive learning tools?

Most adaptive tools only change how hard the questions are. We also track the specific mistake you keep making and pick questions that target it.

How do you handle student data?

We use it to personalize practice and to report progress to the student and the adults linked to them. Read the privacy policy and children's privacy notice.
