What a Frank session actually does

When you're stuck, Frank asks the question your textbook didn't.

Not the answer. Not a paragraph of symbols. The next question: the one that surfaces what you actually didn't see.

You

I keep getting integration by parts wrong. I know the formula. I just always pick the wrong u and dv.

Frank

Try this one: ∫ x · ln(x) dx. Before computing anything, which would be the worse choice for u, and why?(a) u = x(b) u = ln(x)

You

(b)? Differentiating ln(x) gives 1/x, which doesn't simplify.

Frank

Other way. 1/x is the point. Differentiating x gives 1, same complexity as x. Differentiating ln(x)collapses it to an algebraic factor. The rule isn't a guess: pick the u whose derivative makes the integrand simpler. Now try ∫ x · cos(x) dx with that lens.

Every session works this way. Your notes. Your gaps. A question at a time, until the next step is obvious.

How it works

01

Upload your notes or choose a topic

Drop in a PDF, lecture slides, or textbook chapter, or just type a topic and Frank will build a lesson from scratch.

02

Frank builds your study plan

Your document is broken into focused chunks. Questions, flashcards, and a visual blackboard are generated from your content, not generic examples.

03

Learn, practice, and review

Work through explanations, test yourself at three difficulty levels, and use spaced repetition to make it stick long-term.

Memorization fails when the pressure is on.Understanding doesn't.

The reason Frank teaches reasoning, not answers.

Why Frank over ChatGPT?

Four moments where ChatGPT stalls you.

Not a feature list. Four situations every student hits.

ChatGPT

You get the answer. But you still don't know what step you missed.

Frank

Frank teaches through Socratic questions until you find the gap yourself. The answer is a byproduct.

ChatGPT

You paste your lecture notes. The explanation is generic anyway.

Frank

Frank builds from your actual document: your notation, your examples, your professor's phrasing.

ChatGPT

The response is a paragraph of symbols. You read it twice. Still lost.

Frank

Frank draws it on a visual blackboard, step by step. The same way a tutor reaches for a marker.

ChatGPT

One answer and it's over. No way to test yourself or push deeper.

Frank

Frank moves with you: Feynman simplification, Bloom progression, leveled exam practice.

Three teaching techniques, one blackboard

Explain it simply

Feynman

Break dense ideas into plain language until the concept feels obvious. If you cannot explain it simply, you do not understand it yet.

"Imagine the triangle as a ladder leaning against a wall: the hypotenuse is just the ladder itself."

Think, don't just read

Socratic

Ask the next question that forces the learner to reason through the problem rather than copy a finished answer.

"What do you think happens to the hypotenuse if we double side a but keep side b the same?"

Build from recall to mastery

Bloom

Move from recall to understanding, application, and analysis. Each level proves the previous one worked before moving on.

"Now apply it: given sides 5 and 12, find the hypotenuse without looking at the board."

Research-backed

Why this learning model works

  • 01

    Dunlosky, Rawson, Marsh, Nathan, and Willingham (2013) summarize retrieval practice as one of the highest-utility learning techniques.

  • 02

    Self-explanation research shows that explaining ideas in your own words helps surface gaps and strengthens transfer to new problems.

  • 03

    Mixed difficulty, spaced review, and guided retrieval make practice feel harder in the moment but improve long-term learning.

Common questions

FAQ

Why not rely on summary-only tools for math and physics?+

Students often say generic note tools are helpful for theory summaries but weaker on equations, calculations, and symbol-heavy problems. Frank is built for step-by-step reasoning, formula writing, and blackboard visuals that explain the math as it happens.

Can I use Frank for exam prep, not just explanation?+

Yes. Frank can move from explanation into leveled exam prep so you can start easy, push to medium, and finish with hard questions. The goal is not blind confidence from one answer, but repeated guided practice before the test.

What should a good AI tutor feel like?+

Like a patient tutor who knows your notes, explains ideas at different levels, and never gets tired of follow-up questions. Frank is designed to feel like one focused teacher for one student.

Does Frank just give answers?+

No. Frank can teach through Socratic questioning, Feynman-style simplification, and Bloom progression so you actively think through the material instead of only reading finished solutions.

What are students still asking study tools to do better?+

Students want adaptive learning paths, stronger diagrams and simulations, seamless flashcards and quizzes, plus flexible audio and video review. Frank is moving in that direction with blackboard visuals now and additional modes already mapped into the product.

A note from the founder

Frank exists to do one thing: get you to the moment you actually understand.

Not confidence from a slick summary. Not a streak badge for showing up. Real comprehension that holds the morning of the exam, and a year after.
