Text Tools
Count words, convert case, turn Markdown into HTML, test regular expressions and generate placeholder copy, all in your browser. Open DevTools → Network and confirm: nothing about your text leaves your tab.
For writers, devs and everyone in between
A growing set of text utilities for everyday dev and writer workflows: word and character counting, case conversion, Markdown rendering and HTML export, regex evaluation, and placeholder text. No spell or grammar checking, that's a separate category Praticulus stays out of (see FAQ).

Frequently Asked Questions
Does the Markdown preview support GitHub Flavored Markdown (GFM)?
Yes, tables, task lists, strikethrough, and fenced code blocks with syntax highlighting via Prism.js (self-hosted, see privacy). The same GFM parser powers Markdown to HTML.
Can I share a regex pattern via URL?
Yes on Regex Tester (state encoded in the URL hash). URL sharing will be extended to the other text tools. See tool-engagement-url-state in our roadmap.
Will my text content be saved or sent anywhere?
No. The only writes are to localStorage: your preferences and, on the editor tools, a local autosave of your draft. That data stays on your device. Open DevTools → Network before typing and you'll see zero outbound requests.
Why no spell-checker or grammar tool?
Out of scope. Praticulus focuses on dev/utility tools (parsing, formats, encoding, generation). Spell and grammar checking is a distinct category with dedicated players (LanguageTool, Grammarly) that do it better than we ever would.
Does the word counter handle non-Latin scripts like Chinese, Japanese or Arabic?
Yes. The Word Counter uses your browser's Unicode segmentation (Intl.Segmenter) where available, so scripts without spaces between words, such as Chinese, Japanese or Thai, are counted by word rather than as one long token.
