boardCache is your collection of infinite canvas boards for references, inspiration, research, and plans. Pin images, videos, documents, markdown, links, webpages, and more. Draw connections, add timelines, storyboards, task lists and projects when you need structure. Offline-first with optional E2E encrypted sync. The built-in assistant reads your board and acts on it. The desktop app is an MCP server, so agents can build boards too. For web, Mac, Windows and Linux, with a browser clipper.
