A local-first canvas for your AI co‑work.

Jamb is a floating canvas that lives on your Mac. Jamb sheets hold the things you and your AI build together. Use and share your work — without a side of how it was made.

Coming soon for macOS

Built to be yours alone.

Purchased not rented, works with your AI — not ours, everything lives on your mac.

Always at hand

A floating panel appears when you need it and disappears when you don't. A global hotkey keeps the flow unbroken.

Everything belongs

Markdown, code, images, video, PDFs, and sandboxed interactive web artifacts — one surface for everything you keep close at hand.

Works with your AI

A bundled Agent Skill teaches your AI how to build sheets well. An MCP server lets it read, create, and edit them live. Whichever AI you use.

Yours alone

Local-first by design. No account, no cloud, no subscription. Your sheets are files on your Mac that you own.

What belongs in a Jamb sheet? Everything.

Reference docs, cheat sheets, presentation surfaces, interactive tools, utilities, even a morning routine — built once, kept where you can find them.

AI integration — on your terms, in your Settings.

Flip the MCP server on when you want a live link. Export the bundled skill into whatever AI you use.
