Free browser tool

Formula Notebook

Build a private multi-formula notebook with named documents, live previews, duplication, import, export, printing, and local autosave.

A small document workspace without an account

Each formula cell stores editable LaTeX and an optional note in this browser only. Export JSON before clearing browser storage or moving to another device. Markdown export keeps formulas in display delimiters so the notebook can move into compatible documentation systems.

Worked example and guidance

Use Formula Notebook with a checkable example

Example input

A titled cell containing E=mc^2

Expected output

A saved local notebook cell with rendered preview

For the example above, the output should be read as a structured notation output rather than a proof that the underlying formula is correct. Formula Notebook performs the browser-side transformation or calculation, but the mathematical convention, units, domain, and intended publishing format still come from your problem.

How to use it

Enter or paste a small known LaTeX source expression before using a larger real-world example.
Choose the required options and run Formula Notebook; keep the original input available for comparison.
Read the result together with its grouping, command support, and rendered structure, then copy or export only after the check passes.

Useful for

Drafting equations for documents and Markdown
Checking grouping before publication
Moving notation between supported source formats

Limits and checks

Package-specific macros may not be supported by the browser renderer
Visual output can differ from a full TeX engine
Conversion cannot infer missing mathematical semantics

Formula Notebook FAQ

Does Formula Notebook upload my input?

No. The published tool runs in the browser. Avoid placing confidential material in share URLs or exported files that you later send elsewhere.

How should I verify a Formula Notebook result?

Start with the worked example, inspect the grouping, command support, and rendered structure, and compare one result with an independent calculation or representation.

What should I do when the input is rejected?

Reduce the input to the smallest failing LaTeX source expression, check delimiters and supported syntax, then add the remaining structure back one step at a time.
