THINK ON THE PAGE
From a formula
to a clearer idea.
Keep the working where it belongs.
Alongside your thoughts, in your own vault.
See the shape of it.
Preview supported functions from the current equation. Explore polar curves, complex points and explicit XYZ wireframes too.
Numerical graphing within supported domains; not a general equation solver.
Keep the result.
Insert the equation and graph into your note. They become independent blocks. Choose Save view to keep graph navigation changes.
The saved equation remains after closing and reopening the note.

A TOOLKIT FOR SCIENTIFIC NOTES
More of the working.
Less of the friction.
From a lecture note to a lab notebook,
keep your notation close to your thinking.
Visual, LaTeX and Hybrid equation editing
Insert and reopen inline or display LaTeX formulas, including fractions, roots, scripts, integrals and sums.
Scope & limits
Unknown macros and complex TeX may require source editing.
Function, polar, complex-plane and XYZ graphs
Plot supported explicit y=f(x), r=f(theta), z=f(x,y), and rectangular complex points locally.
Scope & limits
Numerical approximations; no general implicit/parametric solver, symbolic algebra, overlays or sliders.
Numerical calculus views
First and second numerical derivatives and finite definite integration for supported real functions.
Scope & limits
Not symbolic differentiation/integration; finite increasing continuous intervals only.
Chemistry and physics writing tools
Format chemical notation, use bounded balance suggestions, insert physics symbols and editable templates.
Scope & limits
Balance suggestions do not establish reaction feasibility; no molecular or physics simulation.
Units and periodic table
Convert among 63 preset unit choices in 11 categories; look up 118 elements.
Scope & limits
Within-category preset conversion and local reference data; no arbitrary dimensional analysis.
Custom formula keywords
Save up to 50 formula shortcuts per vault and expand them in Visual/Hybrid formatted input.
Scope & limits
Keywords do not expand in ordinary notes or the LaTeX source pane.
Your workspace stays local. No runtime account or network connection is required. Downloading and installing the plugin needs access to its distribution source.

Read the release notesA FEW USEFUL DETAILS
Before you
get started.
Have a question or a reproducible issue?
Talk to us on GitHubDoes Visual Math work in this browser?
Visual Math runs inside Obsidian on desktop. This website introduces the plugin and helps you install it in a vault.
Which devices can I use?
This release requires Obsidian 1.14.4 or later and is desktop only. Native checks have used macOS with Obsidian 1.14.4. Windows and Linux have not been verified. Mobile is not supported.
Do I need an account, API key or Node.js?
No runtime account, API key or Node.js is required for the compiled plugin. The editor, bundled data and graph tools run locally. Downloading and installing requires access to the distribution source.
Will an edited equation update its saved graph?
Live equation/graph preview is linked only while its editor is open. Saved formula and graph are separate blocks; navigation persists only when explicitly saved. Changing a saved equation later does not automatically update an existing graph. After moving, zooming or rotating a graph, explicitly choose Save view or Save graph to keep the changes.
Can it solve any equation or calculate symbolic integrals?
Graphing and calculus use numerical methods within supported domains. They are not a general equation solver or symbolic algebra system. Numerical calculus is for supported real functions on finite, increasing, continuous intervals; results are approximations.
What if my LaTeX does not render visually?
Unknown macros and complex TeX may need source editing. Use the LaTeX source view and check the expression. Visual editing does not support every TeX command.
How do I report a problem?
Open a GitHub issue with your plugin version, Obsidian version, operating system and exact steps. Include a small example you are comfortable sharing. Check existing issues first.
What license does the plugin use?
GNU GPL version 3 only with the Obsidian linking exception. See the licensing details for the full terms and third-party notices.
