Big ideas. Clear notation.

Keep the equation, diagram, and explanation in one file.

Math that belongs in your notes

Use $ for inline math and $$ for display equations. KaTeX renders the result in your preview.

Chemistry, without image attachments

Write chemical formulae with mhchem notation inside math expressions. The formula stays editable text.

Diagrams from a few lines of text

Use a fenced mermaid block for flowcharts, sequence diagrams, and more. Edit the text to update the diagram.

Try it in a note

Inline math: $E = mc^2$

Chemistry: $\ce{2 H2 + O2 -> 2 H2O}$
