An AI study tool for your own lectures

The AI study tool
that shows its work.

QuizWhiz is an AI study tool that turns your lectures, slides, PDFs and notes into clean notes, flashcards and practice questions. Everything it makes links to the exact second of your recording, or the page or paragraph it came from, so a wrong answer opens your own material at that spot.

01 · The trace

Get it wrong, and your own lecture plays at that second.

Every note, card and question keeps the exact span of your material it came from. So a miss doesn't just mark you wrong: it shows the answer, why, and the words from your lecture, one tap from the audio.

A missed question showing the key, the reason and the quoted lecture line at 41:30, beside the lecture playing from that second with the line highlighted.

G protein-coupled receptors · Biology, 14 Oct

When a G protein is switched on, which molecule is bound to it?

Not quite

Comes back later in this round and again tomorrow.

Your answer

ATP

Key

GTP

An active G protein holds GTP. It switches itself off by breaking GTP down to GDP.

41:30
“When the signal binds, the receptor changes shape, and the G protein lets go of its GDP and picks up a GTP.”

Biology, 14 Oct

Biology 101 · Lecture, 1:12:40

Cited in G protein-coupled receptors

  1. 41:18

    On the inside it's sitting next to a G protein, and the G protein is holding GDP. That's the off position.

  2. 41:30

    When the signal binds, the receptor changes shape, and the G protein lets go of its GDP and picks up a GTP. That's the on switch.

  3. 41:47

    And it stays on until it hydrolyses that GTP back to GDP. The signal is temporary by design.

  1. 1

    The answer, and why

    The key, a one-to-two sentence reason, and when the item comes back.

  2. 2

    The words from your source

    Quoted from your own lecture or document. Notes are written only from your material, never the open web.

  3. 3

    One tap to the second

    Your lecture plays from 41:30 with the passage highlighted. Close it and you're back on the same question.

02 · How it works

From the lecture hall to the exam, in one study tool.

Notes from what you bring, flashcards and practice questions until it sticks, and a daily review list that knows when your exam is. Studying is never capped.

  1. 01

    Bring what you have

    Record a lecture in the browser, or upload audio, video, a PDF or slides. Paste typed notes or a transcript, or import your Quizlet sets.

  2. 02

    Notes, tied to the second

    Clean notes in sections, without the side talk. Every block links to its second of audio or its page, and your edits keep the link.

  3. 03

    Practice until it sticks

    Cards and questions come from each section's key lines. New items start as multiple choice, then move to typed recall, graded by a published rule.

  4. 04

    Due today, in the right order

    One queue across your courses: nearest exam first, then what you were sure of but got wrong. Review spacing squeezes to fit before the exam.

  5. 05

    See what's still weak

    Weak topics by first-try recall, as plain numbers. An item counts as mastered after typed recall on 3 separate days.

  6. 06

    Back to the notes

    Open the exact passages you missed, then answer questions in wordings you haven't seen. Retakes only count on a later day.

03 · Free tools

Every free tool is the real app.

Each one works fully on a small job, with its limit stated before you start. Anything over a limit is saved and waits with a date. It's never refused.

05 · Honest by default

It cites its sources. It doesn't do your homework.

QuizWhiz earns trust the way a good tutor does: by showing where everything came from, and by being plain about what it is.

  • It says when AI made it

    Every output carries one plain line: “Made by AI from your material. Checked against your source. Report any error.”

  • Checked against your source

    A second model checks every question against the passage it came from. Items that fail are dropped, never shown.

  • Report any error

    Every note and question has Report. It hides for you at once and goes for review.

  • Your work is never lost

    Anything you make before signing up comes with you. Anything over a limit is saved and waits, with the date it will be made.

  • No ads. No grade promises.

    On any plan. And no claims that experts wrote your notes: they come from your own material.

  • Nothing that does graded work

    No essay writers and no homework solvers. QuizWhiz helps you learn what's already yours.

06 · Questions

Before you start

What is QuizWhiz?
QuizWhiz is an AI study tool for your own lectures, slides, PDFs and notes. It turns them into notes, flashcards and practice questions, and everything it makes links back to the second, page or paragraph it came from.
Is QuizWhiz free?
Yes, to start and to keep studying. Your first 3 sources are made in full. After that it's 1 a month (the first 90 minutes or 30 pages; the rest waits), plus 3 short pastes. Anything over the limit is saved and waits, with the date it will be made. A Term Pass makes it straight away; it's one payment and never renews.
Can I check the notes against my lecture?
Yes. Every note, and every flashcard and question made from your material, links to the second of your recording, or the page or paragraph it came from, one tap away. Notes are written only from your material, and a second model checks every question against its passage. Quizlet cards you import and cards you write yourself have no source to link to.
Why not just use ChatGPT to study?
A chatbot answers from anything it was trained on. QuizWhiz writes only from your lecture or document, shows the line of your material behind each answer, and brings back what you missed for review on later days, paced to your exam date.
Is using AI to study cheating?
That depends on your course's rules, so check them, and check before you record a lecture or upload slides too. QuizWhiz doesn't write essays or solve homework. It makes notes and practice questions from material you already have.
Can I bring my Quizlet sets?
Yes. Paste a Quizlet export, copy the text straight from a set page, or bring a CSV file. Every card arrives with its wording and order unchanged. One set at a time is free, and you can export to Anki, CSV or Quizlet format any time.
Can I record on my phone?
Yes, in the browser, with the screen on. If your iPhone will be locked during the lecture, record in Voice Memos and upload the file afterwards.
How long do you keep my recordings?
On a free account, audio and files are kept for 30 days after a source is fully made; with a pass, until 90 days after it ends. Transcripts and page text stay for the life of the course, so every link still works. You can delete a source, a course or your account at any time.

Bring your next lecture.

Notes in sections, questions from the key lines, and every line traced back to the second you heard it.
