Upload the lecture, the PDF, or the notes. Sparky explains the idea in plain language, you teach it back, and a quiz finds the holes. That is the Feynman Technique, on your material.

How it works
Three steps on your lecture
Upload what still feels fuzzy
Drop in a PDF, slides, notes, or a YouTube lecture. One study set holds the source, so Sparky is not guessing from the open web.
Get a plain-language explanation
Sparky walks through the idea, including the figure in your file. If you could not explain it to a classmate, you go again.
Teach it back, then quiz the gaps
Tutor Me puts you on the other side of the desk. You say the idea out loud. A quiz from the same set shows what you still cannot say.
Explain, teach back, then prove it
Plain language, tied to your figure
Sparky Visuals lets you point at a diagram in the notes and ask what it is doing. The answer stays on your lecture, not a generic textbook.
Open Sparky VisualsYou explain it. Sparky catches the hand-waving.
Tutor Me runs a lesson from your study set. You teach the idea back. The holes become the next question, not a surprise on the exam.
Open Tutor MeProof you can say it without the notes
Practice questions from the same lecture. Miss one, and that idea goes back into the explanation loop.

Feynman Technique questions
You pick one idea, explain it in plain language, find the holes, then go back to the source. On StudyFetch, Sparky explains your lecture simply, you teach it back in Tutor Me, and a quiz shows what you still cannot say out loud.
Choose one concept from class, explain it simply, notice where you get stuck, then restudy that part. StudyFetch runs those steps on your PDF or notes: a simple explanation, a teach-back, and a quiz.
Yes. Upload a PDF, PowerPoint, notes, photos of handwritten pages, or paste a YouTube lecture. Sparky explains from that file, not from a generic article.
You can start for free. Sign up, upload a file or a YouTube link, and run your first explanation without paying up front.
Rereading feels fluent and hides the gaps. Teaching the idea back, then taking a quiz, makes the gaps obvious so you can fix them before the exam.
No. Sparky is the partner. Tutor Me and chat sit on the other side of the desk, ask follow-ups, and stay on your material.
