Wndr is a Mac app for people who read a lot of PDFs and want their notes to stay close to the source material.

It gives you one place to collect papers, reports, and reference docs, highlight what matters, and keep Markdown notes alongside them. Everything stays on your Mac.

The easiest way to install Wndr is from GitHub Releases:

1. Open the Releases page.
2. Download Wndr-v0.3.0.dmg.
3. Open the .dmg file.
4. Drag Wndr.app into your Applications folder.
5. Open Wndr from Applications.

If macOS warns you the app was downloaded from the internet, confirm that you want to open it.

Wndr is built for a simple research workflow:

• Import PDFs by drag-and-drop or with the file picker
• Read in a focused, native Mac viewer
• Highlight and annotate important passages
• Write Markdown notes with live preview
• Organize documents with collections and tags
• Search your library by filename or content

When you open Wndr for the first time:

1. Choose where you want your library to live.
2. Import a few PDFs.
3. Start reading, highlighting, and writing notes.

Wndr creates the library structure for you automatically.

v0.3.0 is an early release, but the core workflow is already in place.

Available today:

• PDF import, reading, zooming, and navigation
• Highlights and underline annotations
• Markdown notes with auto-save and live preview
• Collections and tags for organization
• Search across your library
• Native light and dark mode support

In progress:

• Better linking between notes and PDF selections
• A richer inspector panel with more context around documents and annotations

If you want to run the app from source instead of installing the release build:

1. Open Wndr.xcodeproj or Wndr.xcworkspace in Xcode.
2. Build and run the WndrApp scheme.

You’ll need macOS with Xcode installed.
