Text Tools
Test regular expressions, preview Markdown with GitHub Flavored syntax, 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
Three text tools focused on the common dev/writer workflows: live regex evaluation, real-time Markdown rendering (CommonMark + GitHub Flavored Markdown), and on-demand placeholder text. No spell or grammar checking — that's a separate category Praticulus stays out of (see FAQ).
Start with Regex Tester for pattern work, Markdown Preview for writing, or Lorem Ipsum Generator for filler copy.
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).
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 write is to localStorage, for preferences (theme, editor options) — explicitly opt-in, never the content itself. Open DevTools → Network before typing, 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.
When will text case converter and word counter be available?
Planned — see Coming next on this page and tool-saturation-text-v1 in our roadmap. Dedicated HTML entity encode/decode pages are also planned via tool-longtail-encoding-matrix.
