Turn your project folder into a map your agents can read
A canvas-first desktop workspace for thinking with files and agents. Free and open source.

“This” means what you selected
Select a card or a passage and ask. BaseHalf records the selection where Claude Code, Codex and other agents look, so “who asked for this?” is enough.
Working with agents
Connections live in the files
Draw a line from one card to another, and the note gets one more line of plain text in its upstream list, where git and every agent can read it.
How connections work

Generate from what’s on the canvas
Connect frames, clips and notes to an image, video or sound draft, choose a model, and generate with your own provider keys. What comes back is an ordinary file in the folder.
AI images, video and soundWhat else it does
- Tidy up in one move Select a few cards and line them up, or let Tidy Canvas lay out the whole folder along its connections.

- PDFs and books on the canvas A PDF or an e-book is a card with its cover, opens to be read, and agents can see the passage you select.

- Undo puts it all back Deleting asks nothing, because one undo returns the files with their places, descriptions and connections.

- VS Code underneath Files, Git and Search are VS Code’s own, so your branches and diffs work the way they always have.

- Any agent that runs in a terminal Claude Code, Codex, OpenCode or Gemini CLI, side by side in the Agent Area, each in a session of its own.

- Plain files, no account Everything stays in an ordinary folder on your Mac, where git and other editors see it too.

All posts- Context is the interface We typed “improve this” to an agent, and it could not tell what we meant. What it took to fix one word.
- Project management is context management An agent found a request that had fallen out of a plan, and the connections showed the step where it was lost.
- What compounds in thinking Most of what an AI writes for you should be thrown away. A few small pieces make the next round of work easier.
