Split text by rules first, then compare differences and commonalities between two texts. Supports splitting by character, delimiter, prefix, or suffix. Can filter to keep digits, letters, Chinese, etc. All processing happens locally in your browser — no server upload.
Features
- Paste two texts, split by rules, then compare Only A / Only B / Common.
- Toolbar: “Deduplicate split results” (default) or “Keep duplicate split results”.
- Keep digits / letters / Chinese; split by line, delimiter, prefix, or suffix.
Use Cases
- List comparison: Compare two lists to find new, deleted, and common items.
- Tag verification: Compare two tag lists to find differences and common tags.
- Data cleaning: Compare two data sets to identify duplicate and unique content.
How to Use
- Paste content into Text A and Text B.
- Choose dedupe: default “Deduplicate split results”, or “Keep duplicate split results”.
- Click Compare and set retain / split rules in the dialog.
- Review the three result blocks and copy as needed.
Notes
- Dedupe is on by default (set compare). With “keep duplicates”, counts cancel: common gets min(countA, countB); extras go to Only A / Only B.
- Prefix/suffix splitting sorts items by rules.
- After comparison, the summary result (Only A / Only B / Common) is auto-copied.
- Character limit: Max 10,000 characters per session — process in batches if exceeded.
