Toxvas

Toxvas is an offline canvas application for Mac that transforms how you organize and work with notes and ideas. Every card in your workspace is stored as a plain Markdown file in a folder you control, giving you complete ownership of your data. The app provides a visual board interface where you can create connections between cards, add attachments, and record voice notes—all while keeping your content in standard, editable Markdown format that works with any text editor.

Key features include a keyboard-first interface with command palette (⌘K), full-text search across your entire folder using FTS5, attachment support for files and media, voice recording capabilities, and a structured library view. The frontmatter remains editable in any editor, and the app works completely offline with no internet connection required. Toxvas is designed for developers, writers, and knowledge workers who value privacy, local storage, and the flexibility of working with plain text files.
