2D graphing workspace

One workspace. Connected mathematics.

Plot equations, explore data, and check your reasoning with tools that work together.

Graph broadly

Plot more than y = f(x)

Work with explicit, implicit, polar, and parametric relations, plus inequalities and dynamic geometry in the same focused canvas.

y = sin(x)x² + y² = 16r = 2cos(3θ)(x(t), y(t))
Connect representations

Tables, statistics, and regression

Compare values with the graph, summarize data, fit supported models, and inspect residual evidence.

Build and measure

Geometry that stays connected

Create points, lines, circles, polygons, vectors, and constrained objects whose measurements update with the construction.

Investigate further

Analysis and bounded symbolic work

Explore visible roots and intersections, derivatives, integrals, limits, and a declared symbolic subset with honest result boundaries.

Visible rootx ≈ 1.414Check exactness when required
Beyond graph pixels

Trace, summaries, and sound

Follow curves with the keyboard, read structured summaries and tables, or use sonification with a visible data alternative.

Dedicated 3D workspace

Explore another dimension.

Plot explicit, parametric, and implicit surfaces alongside points, curves, and vectors. Rotate the view, inspect cross-sections, and export your work.

  • Multiple surfaces with individual styles and domains
  • Adjustable detail for exploring surfaces
  • PNG images and OBJ geometry export

Guided Student Goals

A clear next step for your mathematics.

Choose a Student Goal in the expression panel. Follow the linked evidence, check the result, and understand what it means.

  1. Start with your mathematicsAn expression, construction, or data table.
  2. Read the linked evidenceValues and diagnostics stay tied to their source.
  3. Check the conclusionEstimates and exact claims remain distinct.

Made for real study sessions

Built for everyday study.

Local projects

Create, rename, switch, save, recover, export, and import projects without creating an account.

Share and present

Create portable share links, export crisp PNGs, print assignments, save PDFs, and keep a .gcalc backup.

Private by default

Equations stay in your browser unless you deliberately export a file or create and send a share link.

Install and work offline

After the first visit, install the app and reopen supported cached workflows without a connection.

Accessible alternatives

Use keyboard navigation, structured graph summaries, tables, reduced motion, contrast themes, Braille input/export, and sonification.

Help when it matters

Search supported syntax, open example projects, follow the product tour, and use plain-language diagnostics to recover from errors.

Learning library

A little guidance goes a long way.
