Download Cardboard Legal Desktop
The desktop observer that watches which apps you work in and drafts time entries for your approval — so billable hours stop falling through the cracks.
Pilot builds are unsigned
These builds are unsigned while we're in early pilot. Your OS may warn you on first launch.
macOS: Right-click the app → Open → click Open in the Gatekeeper dialog. You only need to do this once.
Windows: If SmartScreen appears, click More info → Run anyway.
Signed builds with Apple notarization will ship before public launch.
What the desktop app does
Passive activity tracking
Watches which app is in focus and for how long. App name only — no window titles, no file contents, no screenshots.
Time entry suggestions
Been in Westlaw for an hour? It drafts a time entry for your review. You approve, edit, or dismiss — nothing hits billing without your sign-off.
Matter attribution
Link app sessions to open matters. Cardboard learns which apps you use for which clients over time.
Privacy by design
All processing is local. App name only — no content, no screenshots. Opt out any time from settings.
