About this tool
Make the result useful—not just precise-looking
Review one title per line for length and catalog duplication. Normalized matching ignores case, repeated whitespace, and punctuation so easily missed near-duplicates are visible.
How to use it
- Paste one product title per line.
- Set the character limit used by your destination.
- Check titles and review the status for each line.
Useful for
- Preparing marketplace titles
- Auditing a seasonal catalog
- Finding capitalization or punctuation-only duplicates
Assumptions
- Length uses JavaScript character counting.
- Blank lines are ignored.
- Normalized duplicate detection removes punctuation and folds case.
Limitations
- The checker does not know marketplace keyword, style, or prohibited-content policies.
- Visually similar Unicode characters may not normalize identically.
Common questions
Frequently asked questions
What is a normalized duplicate?
Two titles are normalized duplicates when they differ only in case, punctuation, or spacing after normalization.
Does the checker count spaces?
Yes. The displayed length counts spaces and punctuation in the original title.
What limit should I use?
Use the current limit documented by the destination marketplace or storefront field.
