What's new
TL;DR as a diagram. The summary card has a List / Diagram switch. A diagram shows the whole document's shape at a glance as a Mermaid flowchart, mind map or timeline, and its nodes link to their sections: click one to jump there. Each style is kept with the file, so switching back is instant. Choose the default in Settings ▸ AI Summary ▸ Summary style.
- If the model writes a diagram that can't be drawn, MDViewer asks it once to fix it, then offers the list instead.
- Tested on long design documents from the Go, Kubernetes and React projects.
Huge documents on small models. Notes on the parts of a long document are now merged in rounds until they fit the model, and the list of sections is kept within budget too. No request exceeds the model's context, which matters most for local models (Ollama, LM Studio) that would otherwise silently drop part of the input.
Zoom. The summary now zooms with the document (⌘+ / ⌘−) and lines up with its text column.
Install: download the .dmg for your Mac below (macOS 13 or later), open it and drag MDViewer to Applications. It's signed and notarised, so it opens like any other app.
- Apple silicon (M1 and later):
MDViewer_0.3.2_aarch64.dmg - Intel:
MDViewer_0.3.2_x64.dmg - Not sure?
MDViewer_0.3.2_universal.dmgworks on both, but is bigger. (Apple menu ▸ About This Mac shows which chip you have.)
To open Markdown files with MDViewer by double-click, choose MDViewer ▸ Settings… ▸ Make Default.
