Getting Started & AI Credits
1. Log In or Sign Up
To use the AI Assistant and save your work, please log in or create a new account. Logging in unlocks your daily free AI credits and enables the "Share" feature.
2. Understanding AI Credits
AI Credits are used for premium features like the "Generate with
AI" button, voice input , and "Import
from File" .
You get 10 free AI credits every day with the Free plan. Manual
graphing, plotting, and customization are always free and do not consume
credits.
3. Choose Your Mode
Use the switcher at the top to select your graph type: 2D Graph, Stats Graph, or 3D Graph. Each mode has unique tools and options.
Using the AI Assistant (All Modes)
After logging in, simply describe the graph you want in plain English. The more specific your request, the better the result. This feature consumes AI Credits.
Try prompts like:
- (2D) "Plot a sine wave and a cosine wave from 0 to 4pi"
- (2D) "Graph the trajectory of a projectile launched at 20 m/s at a 45-degree angle"
- (Stats) "Create a bar chart of 10, 25, 18 with labels Apples, Oranges, Bananas"
- (Stats) "A pie chart showing 40% for Team A and 60% for Team B"
- (3D) "Plot a ripple effect where z = sin(sqrt(x^2 + y^2))"
- (3D) "Generate a saddle surface with z = x^2 - y^2"
2D Graph Mode Features
Manual Plotting & Customization
You have full control over your 2D graphs. All manual features are free.
- Datasets: Manage multiple plots on one graph. Add new datasets, change their name and color, and toggle visibility with the icon.
- Add/Edit 2D Data: Manually input your data points as X,Y pairs
(e.g.,
1, 2.5). - Plot Options: After adding data, choose to connect points with straight lines, a smooth curve, or a best-fit line.
- Customize Function: Click "Plot Options" then "Customize 2D Function" to plot any function using the math editor.
- Customize Axes: Use the tabs to change labels, units, ranges, and gridlines.
Stats Graph Mode Features
Easily create statistical charts for your data. All manual features are free.
- Chart Types: Select Pie, Bar, or Histogram from the "Chart Type" card.
- Add/Edit Stats Data: Click the "Add/Edit Stats
Data" button.
- - For Pie & Bar Charts, enter data as
Label, Valuepairs (e.g.,Apples, 50). - - For Histograms, enter one numerical value per line
(e.g.,
5,10,5).
- - For Pie & Bar Charts, enter data as
- Customization: Change the color palette (Pie), set a single chart color (Bar/Histo), make the bar chart horizontal, or adjust the bin size (Histo).
Economics Graph Mode Features
Designed specifically for visualizing economic models and curves. All manual features are free.
- Draw Econ Curves: Click "Plot Custom Econ Curve" to enter standard math equations. Use variables like x, y, p, q.
- Display Options: Toggle between single quadrant (standard economics view) or four-quadrant view. Hide numerical labels to focus purely on the theoretical curves.
- Annotations: Easily add custom text labels using the "Text Tool" at the top to mark equilibrium points or consumer surplus areas.
3D Graph Mode Features
Manual 3D Plotting
- Scatter Plots: Click Add/Edit 3D Data to enter
X,Y,Z data points (e.g.,
1, 2, 5) for a 3D scatter plot. - Surface Plots: Click Plot 3D Function to open
a math editor and define your own function for
z(x,y).
Interacting with the 3D Graph
The 3D canvas is fully interactive:
- Rotate: Click and drag the mouse.
- Zoom: Use the mouse scroll wheel.
- Pan: Hold Shift, then click and drag.
Special Features & Tools
- Explain Mode: (2D Mode Only) Click the icon to
enter a teaching mode.
- - Single Click: Shows the (x, y) coordinates at that point.
- - Double Click: Calculates the gradient and draws the tangent line.
- - Click & Drag: Selects a region to calculate the area under the curve.
- - Annotate: Use the "Annotate" button in this mode to draw, write, or erase on your graph.
- Share Graph: Click the icon (requires login) to generate a unique public link and an iframe embed code for your current graph.
- Graph Gallery: Click the icon to browse and load pre-built graph templates.
Actions & Exporting
Use the buttons in the Actions card to:
- Generate/Redraw Graph: Redraws the graph after you've changed customization settings.
- Download PNG/SVG: Save a high-quality image of your graph. This works for all modes.
- Download CSV/Excel: (2D & Stats Mode) Export your datasets for use in other applications.
