Editorial interest 86/100 Selection signal · not a rating of the site

A browser canvas that combines handwriting, editable code, molecular diagrams, logic circuits, maths, spreadsheets, and charts on one sheet.

Landing page captured for the 2026-08-25 issue.

Field notes

The canvas is organized as a set of embedded scientific instruments rather than a conventional note editor. Its molecule widget accepts element symbols or search input, calculates formula, mass, and name, and can open a 3D companion for measurements. Data work supports XLSX, ODS, and CSV imports, formulas such as =SUM(A2:B4), node-based transformations, and plotting on a coordinate system. The page identifies an accompanying GitHub repository and offers both browser and desktop entry points.
