Can it use the notation of my textbook?

Yes. Add the textbook chapter or your lecture notes to a project and name the file. The sheet uses the symbols of that material.

Can I print it for an exam?

Yes. The sheet is a document you can export and print. Check your exam's rules first: some exams allow only the sheet they supply.

Can I edit the result?

Yes. It is a document in your project. Edit it directly, or ask in the chat for a change, and only that part is rewritten.

Formula sheet maker

Name a course or a topic, or add your lecture notes. Winda writes its formula sheet: every formula you need, what each symbol means, its units, and when the formula applies.

What you get

Formulas in groups: Three to six groups by part of the subject, in the order a course teaches them. Eight to twenty formulas in all.
Symbols and units: Beside each formula, what every symbol stands for and the unit it is measured in.
When it applies: The condition each formula needs, such as constant acceleration, and the case where it fails.
Constants and common mistakes: The constants with their values, and two or three mistakes people make when they pick a formula.

How to use a formula sheet

A formula sheet is one page with the equations of a subject. Some exams give you one, some let you bring your own, and many allow none. In all three cases the sheet is worth making, because most errors in problem solving are not errors of algebra. They come from a formula used where it does not apply.

For that reason a useful sheet holds more than the equations. For each formula it says what the symbols mean, which units go in, and under which condition the formula is true. The equation v = v₀ + at is short; the fact that it needs constant acceleration is what the exam tests.

When you add your course material, the sheet uses your course's notation, which matters when your textbook writes s for distance where another writes x. Solve problems with the sheet open at first. Then cover it and write from memory the formula each problem needs. The sheet has done its work when you no longer look at it.

How it works

Say what it is about
Name a topic, or add a PDF, a lecture video, an article or your own notes. With files, the result is written from them.
Winda makes it
The template sets the form, so you do not write a prompt. You choose the model that does the work: Claude, GPT, Gemini and others.
Keep it and change it
The result is saved in your project beside your files and chats. Ask for a change in the chat, or make flashcards and a quiz from the same material.
