Let your agent show you

A simple Markdown tool that works well with agents

With a little extra vizzy magic sprinkled on top.

Native macOS app A fast, fully native SwiftUI app — no Electron, no web wrapper. Documents Open a single file as a focused document, with Source and Terminal tabs in a side pane. Live editing The whole vizzy/ folder is watched — save a file and the canvas re-renders instantly. Lives in your repo Drop diagrams in a vizzy/ folder — self-contained, versioned, committed with your code. Standard Markdown It's just Markdown — vizzy is a light layer on top, and always falls back to plain text. Manipulate markdown tables Add and remove rows and columns, edit cells inline — vizzy writes clean GFM back to the file. Built-in agents Run a coding agent right in the document's terminal to author and maintain diagrams. Present mode Step through a file's diagrams full-screen like slides, with smooth animations. Annotations & review Drop numbered pins on a diagram and leave comments, like a design review. Link between files Attach a hint to any node or edge to open a related diagram or doc on click. Theming Re-theme the standard palette repo-wide with a single vizzy.config. Render with the CLI Export any diagram to PNG, JPEG, HEIC, or AVIF from the command line. Workspaces Open multiple folders in independent windows; auto-discovery keeps each in sync.
