Intelligently compare the semantic similarity of two texts and get a 0 to 1 score. Ideal for plagiarism checks and content analysis.
When you need to check two pieces of text for plagiarism or duplicate content, our text similarity checker uses semantic analysis algorithms to quantify the correlation between them. The tool processes any plain text paragraphs and outputs a floating-point score between 0 and 1 (where 1 means completely identical). It accurately identifies content that is worded differently but semantically similar.
Q: What does a similarity score of 0.5 mean?
A: It indicates moderate similarity. This means the two texts share some core ideas, but there are significant differences in expression and details.
Q: Can the algorithm detect rewritten or paraphrased plagiarism?
A: Yes. Based on pre-trained models like BERT, this tool detects similarity at the semantic level. It can identify paraphrasing techniques such as synonym replacement and sentence restructuring as long as the core meaning remains the same. However, extreme cases may require manual review.
The maximum limit per check is 2,000 characters. Results are for reference only; academic plagiarism checks should be combined with professional systems. Please do not include personal privacy data when processing sensitive text. Extremely long texts may cause fluctuations in accuracy.
In educational settings, we recommend comparing student assignments with reference materials: a score > 0.7 warrants closer inspection (e.g., an original essay compared to Wikipedia content typically scores < 0.3). Note that the algorithm is highly sensitive to professional terminology, so thresholds may need adjustment for specialized texts in fields like law or medicine.
