Frequently Asked Questions

TextCompare is an advanced text comparison tool that allows you to compare two texts and identify differences between them. It's designed for writers, editors, developers, researchers, and anyone who needs to compare text documents. Our tool highlights differences, calculates similarity scores, and provides detailed analysis of the compared texts.

Yes, the basic version of TextCompare is completely free to use with no registration required. We also offer premium features for advanced users with larger text comparison needs, which require a subscription. You can find more information about our pricing on our Pricing page.

No, you don't need to create an account to use the basic features of TextCompare. However, creating an account allows you to save your comparison history, access premium features, and customize your experience.

Yes, your data security is our priority. All text processing occurs in your browser, and we do not store or save the text content you compare. Your text data is not transmitted to our servers, and once you leave the page or clear the tool, the text data is permanently deleted. For more information, please refer to our Privacy Policy.

To compare two texts:

1. Paste your original text in the "Original Text" field
2. Paste your modified text in the "Modified Text" field
3. Click the "Compare Texts" button
4. View the results showing similarity score, differences count, and highlighted differences

The similarity score is a percentage that indicates how similar the two texts are. A score of 100% means the texts are identical, while a score of 0% means they are completely different. The score is calculated using a combination of character-level and word-level similarity algorithms to provide the most accurate assessment.

In the comparison results:

• Added content (present in the modified text but not in the original) is highlighted in green
• Removed content (present in the original text but not in the modified) is highlighted in red with a strikethrough
• Unchanged content appears in normal text

This visual highlighting makes it easy to quickly identify what has changed between the two texts.

The free version of TextCompare allows you to compare texts up to 10,000 characters each. For larger text comparisons, you can upgrade to our premium version, which supports comparing texts up to 100,000 characters each and offers additional features like batch comparison and export options.

TextCompare works on all modern browsers, including:

• Google Chrome (recommended)
• Mozilla Firefox
• Microsoft Edge
• Safari
• Opera

For the best experience, we recommend using the latest version of your browser.

Yes, TextCompare is fully responsive and works on smartphones and tablets. However, due to the nature of text comparison, the experience is optimized for devices with larger screens. For complex comparisons, we recommend using a desktop or laptop computer.

TextCompare currently supports plain text comparison only. Formatting, images, and other non-text elements will be stripped when you paste content into the comparison fields. If you need to compare formatted documents, we recommend extracting the text content first or using a specialized document comparison tool.

TextCompare uses a combination of advanced algorithms for accurate text comparison:

• Levenshtein distance for character-level similarity
• Jaccard index for word-level similarity
• Longest Common Subsequence (LCS) for identifying specific differences

This multi-algorithm approach ensures high accuracy in detecting even subtle differences between texts.
