Text tools

These tools work on pasted text content — you bring the text, they transform or analyze it. The boundary with the Files category is input method: paste content here, upload binary files there. Writers counting words, developers slugifying strings for URLs, SEO specialists checking keyword density, editors comparing two versions of a document — these are the tools for that work.

The analyze subcategory measures text. The word counter is a multi-output tool: it reports character count (with and without spaces), word count, sentence count, paragraph count, estimated reading time at 200 words per minute, and a Flesch reading ease score — all from one paste. The readability checker goes deeper on the Flesch scale, adding Gunning Fog index and grade-level equivalents. A keyword density analyzer shows which words appear most frequently and at what percentage of the total word count, which is useful for checking whether a piece is over-optimized for a target phrase before you publish it.

The transform subcategory modifies text in place. The case converter handles eight output formats simultaneously: lowercase, UPPERCASE, Title Case, Sentence case, camelCase, PascalCase, snake_case, and kebab-case. A slug generator applies the full URL-safe transformation (accent stripping, special character removal, hyphenation). Strip HTML tags removes markup while preserving the content, sort lines alphabetizes or reverses a list, and find-and-replace handles literal or regex pattern matching across a pasted block.

The compare subcategory is for side-by-side text analysis. The text diff tool shows additions, deletions, and unchanged lines between two blocks of text — the same output you'd get from diff -u in a terminal, without opening a terminal. A similarity checker computes the Levenshtein edit distance and Jaro-Winkler similarity score between two strings, which is useful when you need to know whether two strings are close enough to be considered the same (typo tolerance, fuzzy matching thresholds).

The format subcategory handles markup conversion. A Markdown preview renders your Markdown to HTML in real time in a split panel. A Markdown-to-HTML converter produces clean, copyable HTML from a Markdown source, and the reverse tool goes from HTML to Markdown. These are for markup interchange — converting a README to a blog post, pasting Markdown into a system that expects HTML — not for converting between file formats like DOCX or PDF, which belong in the Files category.

What these tools don't replace: a full writing environment, a version control system, a CMS, or a grammar checker. They're focused single-purpose pages for one-shot transformations. If you're editing the same document repeatedly, a tool like Google Docs or Notion with revision history is the right environment for that.
