Text & String Tools

Free text utilities for writers and developers: count words, convert cases, generate placeholders, create slugs, encode text, analyze keyword density, and work with Markdown. All client-side.

Text manipulation is a constant need across writing, content creation, development, and data work. The Word Counter and Sentence Counter give writers immediate feedback on length, reading level, and sentence structure — useful for blog posts, documentation, academic writing, and social media character limits. The Case Converter and Title Case Converter handle the transformations developers need when working with variable naming conventions (camelCase, snake_case, kebab-case, PascalCase) or preparing headings for publication.

The Slug Generator converts any text into a clean, URL-safe slug — removing special characters, replacing spaces with hyphens, and lowercasing the result — which is essential for CMS workflows, blog post URLs, and database keys. The Diff Checker highlights line-by-line and character-level differences between two text inputs, which is useful for reviewing document revisions, comparing configuration files, or spotting subtle changes in API responses.

The Markdown tools cover the full workflow from drafting to publishing: the Markdown Preview renders live HTML output as you type; the Markdown to HTML converter outputs clean HTML you can paste into a CMS or template; and the Table Formatter aligns pipe-separated Markdown tables that are painful to maintain by hand. The keyword density and Lorem Ipsum tools round out the content creation toolkit.
