Frequently Asked Questions
Are these tools really offline?
Absolutely. Once the page is loaded, all logic executes locally on your device. We do not store or transmit your sensitive data to any server, making it 100% private and secure.
What is the difference between Free and Pro?
Free tools are available to everyone with a daily usage limit. Pro tools offer more advanced algorithms (like Plagiarism Checking or Flowchart Generation), feature unlimited usage, and allow for data exports.
How accurate is the Plagiarism Checker?
Our Plagiarism Checker use a Levenshtein distance algorithm to compare two texts. While it's great for spotting similarities between documents, it doesn't search the entire web – it's designed for comparing local sources or multi-draft analysis.
Do I need an internet connection to use the tools?
You only need an internet connection to load the tool page for the first time. Once loaded, you can disconnect, and the tool will continue to function perfectly as all the logic is inside your browser.
Which programming languages do the Code Tools support?
Our formatters and minifiers work best with JavaScript, JSON, HTML, and CSS. The Regex Tester supports standard PCRE patterns, making it compatible with most modern development environments.
Can I request a new tool?
Yes! We are constantly expanding our library based on user feedback. If you have a specific utility in mind that would help students or developers, feel free to contact us with your suggestions.
