Frequently Asked Questions
Everything you need to know about Text Compare
What is text comparison?
Text comparison is the process of identifying differences between two pieces of text. Our tool uses an advanced algorithm to detect additions, deletions, and modifications at both character and word levels, making it easy to track changes in documents, code, or any text content.
How accurate is the text compare tool?
Our text comparison tool uses the Longest Common Subsequence (LCS) algorithm, which is highly accurate for detecting differences. It can identify even single character changes and provides both word-level and character-level comparison modes for precise analysis.
What's the difference between word and character level?
Word-level comparison treats each word as a unit and highlights entire words that differ. Character-level comparison checks every single character, making it ideal for catching typos or small code changes like a missing semicolon.
Can I ignore case and whitespace?
Yes! You can enable 'Ignore Case' to treat uppercase and lowercase letters as equal, and 'Ignore Whitespace' to focus only on actual content differences while ignoring spacing variations.
Is there a file size limit?
Text Compare can handle large texts efficiently. For best performance, we recommend texts up to 1MB each. The tool processes everything in your browser, so your data remains private and secure.
Is my text data saved or stored?
No, your text data is completely private. All comparison happens locally in your browser using JavaScript. We use localStorage to save your session temporarily, but nothing is sent to our servers. You can clear your data anytime.
Can I compare code files?
Yes! Text Compare is perfect for comparing code files. You can drag and drop .txt or .md files, or paste code directly. The side-by-side and unified views make it easy to review code changes, similar to Git diff views.
What are the use cases for text comparison?
Text Compare is useful for: reviewing document revisions, comparing code versions, checking contract changes, analyzing article edits, detecting plagiarism, proofreading translations, and tracking content modifications across versions.
Can I export the comparison results?
Yes! You can copy the diff to your clipboard or download it as a .txt file. The exported format shows additions with '+' and deletions with '-', similar to standard diff formats used in version control systems.
