Remove Duplicate Lines for developers
For developers, Remove Duplicate Lines fills a gap most developers run into daily: a small text task that doesn't justify opening a heavyweight editor, but that doing by hand is error-prone. Open the page, paste, do the thing, paste back.
Common developers workflows
- Quick checks before sending — counts, capitalization, formatting
- Cleanup of pasted-in content from another source (Word, Slack, web pages)
- Format conversion to fit a target medium with strict character limits
