/capabilities
A fast diff checker for code and plain text
Clear changes
Line-level changes use explicit plus and minus markers, with word-level highlights for manageable changed lines.
Bounded work
Large unchanged sections collapse automatically. Highly divergent regions fall back to a coarse summary instead of freezing the page.
/faq
Text comparison questions
Are my texts uploaded?
No. Both inputs are compared in a dedicated browser worker. Text, filenames, and diff content are not included in analytics events.
What files can I compare?
Any plain-text format is suitable, including TXT, JSON, YAML, XML, Markdown, source code, configuration files, and CSV.
What is the input limit?
Each side accepts up to 10 MB. Very large or highly divergent sections may be summarized to protect browser responsiveness.
