What this text similarity checker does
This tool compares two pasted text blocks and estimates how similar they are based on shared words and exact matching sentences. It is useful when reviewing drafts, checking whether two versions are too close or comparing source notes with a rewritten paragraph.
The checker runs in your browser and only compares the text you paste. It does not search the internet or replace a formal editorial review. Use it as a practical writing helper before publishing.
Good use cases
- Compare an original draft with a revised version.
- Check whether rewritten content still follows a source too closely.
- Find matching sentences between two text blocks.
- Review guest posts or team drafts for repeated wording.
