Who it's for

  • People organizing research or ideas who want a visual canvas with notes, PDF highlights, and linked material.
  • Developers using Claude Code, Cursor, or Codex who want MCP agents to work directly with their local notes and boards.
  • Obsidian or Heptabase users who want to import an existing vault or backup into a visual Markdown workspace.

How it fits your workflow

Create or import a board, then arrange Markdown cards, links, sections, images, and other material on the infinite canvas. Cards can also hold checkboxes that appear in the Tasks kanban, and PDFs can be highlighted with passages turned into source-linked cards.

Key features

Infinite canvas
Arrange Markdown cards, connectors, mind maps, images, freehand ink, and colorable sections on an open-ended board.
Markdown files and readable boards
Cards are plain Markdown and boards are readable JSON in a folder chosen by the user, so files can be opened in an editor, searched, backed up, or used by scripts.
Tasks and kanban view
Checkboxes in cards are gathered into a Tasks view with Open, In Progress, and Done lanes. Boards act as swimlanes, and due dates can be added with @due(date).
MCP agent editing
Claude Code, Cursor, and Codex can connect over MCP to search the graph, write cards, create connections, and frame sections on the board.
Built-in AI assistant
The AI dock can use a user-provided key for Claude, GPT, or Gemini, or run with Ollama or LM Studio. It can make board edits, with card rewrites presented as word-level diffs for approval.
Reviewable agent changes
Agent activity records who changed what and when. Users can inspect note diffs and session summaries, review changes, and revert supported edits with safeguards for newer work.
