When a browser-based tool is enough
Deduplicate and sort lists while preserving the original order. A focused browser utility is often the better choice when the work is temporary, the input should remain private, and a team needs something that opens immediately on different devices.
More complex platforms can be valuable when a workflow needs team permissions, long-term history, integrations or automated reporting. Avoid paying for that overhead when the immediate requirement is simply to complete one clear action.
