Frequently Asked Questions
Is my text data safe?
Absolutely. SlipCompare processes everything locally in your browser using JavaScript. Your text is never transmitted to any server. This makes it safe for comparing sensitive content, proprietary code, or confidential information.
Can I compare very long texts?
Yes. SlipCompare can handle large text comparisons, though very large files may take a moment to process depending on your device. For best performance, we recommend texts under 100,000 characters, but there's no hard limit.
Does it work offline?
Once the page is loaded, the text comparison functionality works offline since all processing happens in your browser. You don't need an internet connection to compare texts.
