Frequently Asked Questions

How accurate is the duplicate word detection compared to professional proofreading tools?

Our duplicate word detection is highly accurate for common repetition errors like 'the the' or 'and and'. The tool uses context-aware analysis to distinguish between accidental duplicates and intentional repetition. While it focuses on adjacent word duplicates rather than distant repetition, it catches the most common typing errors that occur during editing and revision processes.

Will the tool flag intentional word repetition in creative writing or technical content?

The text linter includes context awareness to minimize false positives. It distinguishes between accidental duplicates (like 'the the') and intentional repetition in lists, titles, or stylistic elements. However, for highly stylized creative writing with deliberate repetition, you may need to manually review flagged items. The tool prioritizes catching genuine errors over perfect context recognition.

Does this tool send my text to external servers for analysis?

No, absolutely not. All text analysis happens entirely within your browser using JavaScript. Your text never leaves your device or gets transmitted to any servers. This ensures complete privacy for sensitive documents, personal writing, or confidential business content. The tool works offline once the page is loaded, making it safe for any type of content.

Can this tool replace professional proofreading or advanced grammar checkers?

This tool excels at specific tasks - finding duplicate words and spacing issues - but it's designed as a focused utility rather than a comprehensive grammar solution. Think of it as a specialized lint tool for common text formatting problems. For complex grammar, style analysis, or comprehensive writing review, you'd still want professional editing or full-featured grammar checkers.

What types of spacing and formatting issues does the tool detect?

The tool identifies multiple consecutive spaces, mixed tabs and spaces, trailing whitespace at line ends, and irregular spacing patterns that can occur when copying text from different sources. It's particularly useful for cleaning up text that's been copied from PDFs, emails, or formatted documents where spacing can get mangled during the copy-paste process.
