Frequently Asked Questions

Which text tools work offline?

Client-side tools like the Word Counter, Text Case Converter, Lorem Ipsum Generator, and Text Diff work fully offline once loaded. AI-assisted tools (Grammar Checker, Paraphrase Tool, Summarizer) require internet access because they send text to an AI API for processing.

Is my text stored or logged?

For client-side tools, text never leaves your browser. For AI tools, text is sent to the AI API for analysis and immediately discarded — we do not store, log, or share any submitted text.

What is the difference between the Paraphrase Tool and the Grammar Checker?

The Grammar Checker finds and corrects errors in your existing text. The Paraphrase Tool rewrites the text in a different style (formal, casual, shorter, longer, creative) while keeping the same meaning. Use the Grammar Checker to fix mistakes, and the Paraphrase Tool to change tone or style.
