Hide From Screen Capture

Obsidian plugin that excludes all Obsidian windows (main window and any popped-out panes) from screen-share/recording capture on Windows, using SetWindowDisplayAffinity(WDA_EXCLUDEFROMCAPTURE) via Electron's BrowserWindow.setContentProtection().

How it works

• A ribbon icon (left sidebar) toggles capture-hiding on/off.
  • Protected: eye-off icon, highlighted.
  • Unprotected: eye icon, normal.
• Hiding is enabled by default on first install.
• The toggle state persists across restarts.
• Obsidian's Settings dialog is an in-window modal (not a separate OS window), so it is automatically covered whenever the main window is protected. Popped-out tab windows are protected too, via Obsidian's window-open workspace event.
• Windows-only. On other platforms the ribbon button is inert (no-op, no errors).
• Disabling/removing the plugin turns protection back off on unload.

Install (manual / dev)

npm install
npm run build

Then copy (or symlink) manifest.json, main.js, and styles.css into <vault>/.obsidian/plugins/hide-from-capture/, and enable the plugin from Obsidian's Community Plugins settings.

For iterative development, use npm run dev (esbuild watch mode) and symlink the plugin folder into your vault so rebuilds are picked up without recopying.

Verifying it works

Press Win+Shift+S (Snipping Tool) and try to capture the Obsidian window while protection is enabled — it should appear black or be omitted from the capture. Toggle the ribbon button off and repeat to confirm the window captures normally again.
