An online whiteboard for AI-assisted research.

A clear path from idea to result

  1. 01

    Start a canvas

    Create a whiteboard in the workspace and add your topic and supporting material.

  2. 02

    Connect the ideas

    Add text, shapes or sketches and use arrows to express processes and relationships.

  3. 03

    Save and discuss

    Tidy the canvas and share the result with a read-only link or PNG export.

Tools for the way you work

Capture ideas directly

Pens, watercolor strokes, arbitrary-angle lines and an eraser make sketching immediate.

Text and structured nodes

Place freeform writing and structured components in the same space.

Drag to connect

Drag an arrow from a shape or component's plus control until it snaps to a target.

Choose your line style

Switch between hand-drawn and business styles and adjust color, width and opacity.

Put it to work

Process discussions

Arrange steps and decisions on a canvas and use arrows to check for missing connections.

Visual notes

Combine short text, sketches and structured nodes while studying or discussing.

Research organization

Group topics and claims around a question to discover relationships between sources.

Questions before you start

A whiteboard allows freeform placement of text, shapes and drawings. A mind map focuses on a tree hierarchy of topics and branches.

Pens, watercolor strokes, lines and an eraser are available, with controls for color, width and opacity.

Select a shape or component, drag from its plus control, and move the arrow to a target to create a snapped connection.

Use the existing read-only sharing controls or export PNG. Permissions and allowances depend on your account.

Continue in your workspace

Your documents, canvas and maps belong in one workflow.
