Text Tools
Free online tools for counting, cleaning, converting, sorting, and analyzing text
Text manipulation is a universal task — writers checking word counts, developers converting variable naming conventions, SEO specialists analyzing keyword density, data engineers cleaning duplicate lines from exports. These jobs don't need a subscription or a desktop app. They need fast, reliable tools that work right in the browser.
MODOO HUB's 16 text tools cover the full spectrum from analysis to transformation. The Keyword Density Analyzer helps writers and SEOs optimize content without over-stuffing. The Text Diff Checker compares two text versions side-by-side with highlighted changes — like Git diff for plain text. The Case Converter handles camelCase, snake_case, kebab-case, and 4 other conventions used daily in programming.
All tools are instant, client-side, and handle texts of any length. Paste your content and results appear immediately.
What does the Keyword Density Analyzer measure?
It counts how often each unique word appears in your text and shows the percentage (density). A keyword density of 1–3% is generally recommended for SEO-friendly content writing.
How does the Text Diff Checker work?
Paste two versions of text and the diff checker highlights additions in green and deletions in red, line by line — similar to how Git shows file changes. Useful for proofreading and version comparison.
Can I use the Case Converter for programming naming conventions?
Yes. The Case Converter supports camelCase, PascalCase, snake_case, kebab-case, UPPER_SNAKE_CASE, and Title Case — useful for variable names, API keys, filenames, and CSS class names.
What is the Remove Duplicate Lines tool useful for?
It removes repeated lines from any text block. Useful for cleaning log files, deduplicating keyword lists, removing repeated entries from CSV exports, or cleaning up list-based content.
