Infinite canvas
A freeform, infinite workspace for arranging notes, images, links, and files in one view instead of spreading project context across separate apps.
Causal
Causal is an AI canvas workspace for moodboards, notes, files, and links on one infinite board, with full-context AI, a macOS app, and sharing.
Overview
Causal is an AI canvas workspace for planning visual projects in one place. The homepage describes it as an infinite canvas for moodboards, notes, files, and links, with a built-in agent that can read the whole board instead of treating each item in isolation.
It is positioned for people who want to organize scattered inspiration and project material into a single visual workspace. The site shows example boards for product planning, brand research, onboarding, storyboards, video planning, and website moodboards, which suggests a focus on creative and planning-heavy workflows rather than linear document editing.
Features
Text editor
A built-in text editor for storing important information in text files directly on the board.
Image and video handling
Support for pasting images and videos from the clipboard so visual references can live next to notes and links.
Organization tools
Collections and an unsorted tray for grouping related items or parking files that do not yet belong in a board.
Desktop sharing workflow
A desktop app for macOS plus shareable links for sending workspaces to collaborators.
Context-aware AI agent
An AI-powered board agent that reads the full canvas, including text, images, links, and spatial relationships, and can create and place content on the board.
Use Cases
Product design planning
Use Causal to map a product idea from problem statement to screen order, while keeping references and notes on the same board.
Brand and visual research
Build moodboards and brand boards with palettes, typography references, and voice notes arranged side by side for review.
Team onboarding and instructions
Organize onboarding steps, internal instructions, and supporting files into a sequence that is easier to review and revise.
Storyboarding and video planning
Plan a video, film, or content brief by placing the script, references, deliverables, and assets in one workspace.
Research and synthesis
Collect source links, embedded documents, and notes for a topic and let the AI agent work from the full canvas context.
