This is a powerful, free online duplicate remover tool that combines multiple text processing features in one place. It serves as a line counter, word counter, character counter, and comprehensive text deduplication tool. Our tool removes duplicate lines and/or duplicate words from your text while providing real-time statistics including line count, word count, character count, and characters without spaces.

Our line counter provides instant, accurate line counting for both input and output text. The line count updates automatically as you type or paste text. This feature is perfect for:
• Counting total lines in documents, code files, or data lists
• Tracking how many lines contain data before and after deduplication
• Verifying the number of entries in lists, CSV files, or database exports
• Measuring text length and structure
The line counter counts each line break as a separate line, giving you precise metrics for your text data. Use it as a standalone line counting tool or combine it with our deduplication features for comprehensive text analysis.

The built-in word counter delivers real-time word counting with precision. Our word count tool intelligently identifies words by splitting on whitespace and filtering out empty entries. Perfect for:
• Counting words in essays, articles, and blog posts
• Tracking word count before and after removing duplicates
• Measuring content length for SEO optimization
• Verifying word limits for academic or professional writing
• Analyzing data entries and list items
The word counter updates instantly as you type, providing immediate feedback. It excludes newlines and empty strings, ensuring accurate word counts. This makes it an excellent free alternative to Microsoft Word's word counter or other online word counting tools.

Our advanced character counter provides TWO types of character counting:

1. Total Characters: Counts all characters including spaces, punctuation, and symbols (excluding empty newlines). Ideal for:
• Measuring total text length
• Checking character limits for social media posts (Twitter, Facebook, Instagram)

• Analyzing document size

2. Characters Without Spaces: Counts only letters, numbers, and symbols, excluding ALL whitespace. Perfect for:
• Precise content measurement

Both counters update in real-time, making this a powerful letter counter and character counting tool for any text analysis needs.

Absolutely! Our tool prioritizes privacy and data security. All text processing and deduplication happen locally in your browser, meaning no data is sent to a server. This ensures your sensitive lists remain private and secure, making it ideal for text cleanup and list management without compromising privacy.

Yes, our tool can handle large lists for deduplication and text processing. However, extremely large lists may slow down your browser due to processing constraints. For optimal performance, we recommend breaking very large lists into smaller chunks to ensure smooth text cleanup and efficient list management. This approach maintains accuracy and speed.

Use our text processing tool at your own risk. While we strive for accuracy in deduplication and text cleanup, always verify the results for critical tasks to ensure precision.
