Toxvas

Toxvas is an offline workspace canvas for Mac where every card is a plain Markdown file in a folder you choose. Arrange cards on boards, render headings, lists, tables, quotes, code fences and frontmatter, and connect ideas with ink connectors. It also supports attached files, voice notes, local full-text search and keyboard commands. The folder structure remains accessible in Finder, any editor or Git, while shell-capable agents can read and write boards without an account or API key. Toxvas requires macOS 14 or later and Apple silicon.
