What this tool does
Duplicate Content Similarity Checker gives you a fast, focused way to compare two text blocks with complementary lexical and phrase-overlap metrics, readable findings, and a clearly labelled heuristic assessment. Everything runs locally in this tab.
The result is produced only after the input is checked. If the value cannot be processed, the workspace reports a specific error instead of guessing.

Limitations
Review important output before using it in production.
Very large inputs remain subject to browser memory limits.
Similarity is heuristic and does not represent a search-engine penalty, index selection, plagiarism ruling, or semantic-equivalence score.
Boilerplate, very short samples, and language-specific tokenization can affect the result.
