How it works
Words and pictures from your lecture
Upload the page with the figure
Drop in a PDF, slides, or notes that include the diagram you have to learn. Dual coding needs both the words and that picture, from your file.
See the idea next to the figure
Sparky Visuals lets you point at the diagram and get an explanation in words. Verbal and visual at once, tied to the page you uploaded.
Quiz both channels
Practice questions from the same lecture. If you can name the figure and say what it is doing, the idea is actually in.
Words, pictures, then proof
Ask the diagram on your page
Point at a figure in your notes and get an explanation grounded in that lecture. The picture and the words stay together.
Open Sparky VisualsNotes that keep the figure attached
Structured notes from the same PDF, including the figures. You read the idea and still see the picture it belongs to.

Dual coding questions
Dual coding is studying an idea in words and in a picture at the same time, so memory has two ways back to it. On StudyFetch, you upload your lecture, Sparky explains the figure in words, and a quiz checks both.
Dual coding theory says verbal and visual information are stored in related traces. Studying with both is stronger than rereading text alone. StudyFetch runs that on your PDF: the figure on the page, an explanation in words, then a quiz.
Yes. Upload a PDF, PowerPoint, or notes that include figures. Sparky Visuals stays on that page, so the picture you study is the one from class.
You can start for free. Sign up, upload a lecture with a figure, and run your first explanation without paying up front.
Rereading uses one channel and feels fluent. Dual coding makes you look at the figure and say what it is doing. The quiz is how you find out whether both traces are actually there.
Feynman is explain it simply, then teach it back. Dual coding is pair the words with the picture. You can use both on the same study set: see the figure, then explain it in plain language.
