What this hub is built for

  • Fast first-pass clarity on duplicates, naming, junk files, and photo metadata.
  • No hidden apply step: browser tools analyze and preview only.
  • Clean handoff into DupeZappa for real batch actions with undo.

Best starting point

Use browser tools to decide. Use DupeZappa to execute.

Run a focused scan, validate the output, and then switch to the desktop app for destructive steps like rename, move, or delete.

Recommended flow

Three steps from scan to safe apply.

1

Pick one tool from the index above.

Start with the exact problem you want to resolve today: duplicates, rename patterns, junk clutter, or photo metadata.

2

Run the scan and review the preview output.

Each tool is local and non-destructive, so you can inspect recommendations and edge cases before committing anything.

3

Move to DupeZappa when you are ready to apply.

Use the desktop app for guarded batch actions, conflict handling, and undo history once the plan looks correct.

Execution boundary

Keep the browser pass and apply pass clearly separated.

The free pages are for analysis and planning. The desktop app is for high-impact operations where preview depth, conflict handling, and undo history matter.
