A SHORT GUIDE
Make a sheet you can actually use.
A cheatsheet is a compact reference for information you repeatedly look up: definitions, formulas, commands or steps. The useful part is choosing what belongs on it.
- Start with your material. Pick a template, paste plain text or import a .txt or .md file. Templates are editable starting points, not a substitute for your course material.
- Group related ideas. In Paste notes, start a heading with
#or##. Body text is retained, including long paragraphs. There is no automatic AI summary. - Edit the essentials. Keep each section focused. Add, remove or reorder sections. Write
**bold**,`code`, or start a line with a hyphen for a bullet. - Typeset formulas. Use
$x^2$for inline math or$$ rac{a}{b}$$for a displayed equation. Check the preview; unsupported or invalid math stays visible. - Choose your page. In Layout, pick A4 or Letter, portrait or landscape, and one to four columns. Fit to one page reduces text size to a minimum of 9px. Trim notes if they still overflow.
- Keep a copy. Download PDF for a one-page raster document, Print for your browser’s print dialog, or Save editable JSON to preserve editable text and settings. Markdown is a plain-text backup.
Print settings that matter
Select the same paper size and orientation as the preview. Use 100% scale, zero margins and no browser headers or footers. Enable background graphics to retain section colors. The downloadable PDF fixes the page size and contains a rendered image; its text is not selectable.
What the page-fit check means
The percentage compares the natural rendered content height to the usable page height. It is a layout estimate, not a measure of how thoroughly a subject is covered. Wide formulas and excess height disable exporting until corrected. Always read your final PDF at actual size.
A small example
For a probability sheet, use sections such as Definitions, Probability rules and Common mistakes. Include a formula together with the condition under which it applies. Removing that condition to save room makes the sheet less useful.
Use and limits
Verify formulas and examples against your own sources. Only bring a reference sheet to an exam when the rules permit it. This edition supports text, Markdown and Sheetmint JSON; PDF extraction and AI summarization are not included.
