The Socratic AI tutor

Every tutor can hand over the answer. It lives at the surface.

Understanding lives further down. Scroll — we'll take you there.

0 m · The surface

The answer.

Minimum 3, at x = 2. Any app can hand this over in a second — and nothing sticks.

f(x) = 2x² − 8x + 11 → min = 3 at x = 2
−40 m · The method

The how.

Completing the square, step by step. Better — but it is still someone else's thinking, read off a screen.

2(x² − 4x) + 11 → 2(x − 2)² + 3 → vertex (2, 3)
−80 m · The break

Where the reasoning bent.

This student drops the leading 2 when balancing the constant — same slip as July 24. This is what DoubleDive hunts for, by asking instead of telling.

2(x² − 4x + 4) + 11 − 8 ← the step that keeps breaking

Yours for good.

Six generated problems built on the same trap with new numbers. When these fall, the concept is truly theirs — that's the double dive.

Back at the surface

What comes back up with them

Every session ends deeper than it began — and everything found down there is kept.

01

A review book that writes itself

Each dive is filed with weak-concept tags, automatically.

02

A daily challenge

One problem a day, one step harder, built from their own history.

03

More than one way to solve it

Beyond the route you took — two or three genuinely different paths to the same answer.

Works on desktop, laptop, tablet, and phone — no install, right in your browser.

Orchestration

Why one DoubleDive is enough

DoubleDive doesn't rely on a single AI. For every problem it conducts the model best suited to solve it, has the models cross-check each other, and turns the result into a Socratic dialogue.

01

Accuracy beyond any single model

The best model is selected for each problem type, and the models cross-verify each other. The benchmark above is the proof.

02

One subscription is all you need

No need to pay for several AI subscriptions. With DoubleDive alone, every problem gets the best combination available at that moment.

03

It gets stronger in real time

The moment any underlying model is upgraded, DoubleDive's orchestration instantly becomes that much more powerful.

FAQ

Frequently asked questions

Does DoubleDive just give my child the answers?

No — that's the whole point. The Socratic tutor responds with guiding questions and hints until students reach the answer themselves, then generates similar problems at each difficulty until the concept sticks. Step-by-step explanations are available when you want them.

Which subjects and grade levels are covered?

All core subjects — math, language, English, science, and social studies — from pre-K through high school, including exam-level problems. For US students that includes 35+ AP courses: AP Calculus AB/BC, AP Statistics, AP Physics, AP Chemistry, AP Biology, AP US History, AP Psychology, AP English Language, AP Economics and more. Math is where DoubleDive is strongest, with perfect scores on AIME 2026 I and JEE Advanced 2026 Math.

Is there a free plan?

Yes. You get a 3-day free trial of Pro on signup with no card required, and 1 free problem every day forever. Socratic tutoring, step-by-step explanations, and concept chat are always free. The 3-day trial comes with signing up — a paid Pro plan ($14.99/mo, or $4.49/week for a short sprint) starts as soon as you subscribe.

How do I cancel? What about refunds?

The 3-day signup trial takes no card, so it can never charge you. Once you subscribe, cancel anytime. Payments are processed securely by Stripe. For billing questions or refund requests, email support@doubledive.ai; refunds follow our Terms of Service.

Do purchased credits expire?

No. Credit packs never expire — use them at your own pace. They also work as top-ups for subscribers who want extra problems beyond the daily 30 included with Pro.

Can parents and teachers see progress?

Yes — through Teacher Mode, which gives academies, tutors, and homeschooling parents per-student diagnostic reports, homework packs, and a live dashboard.
