About these tools
This is the utility drawer for anyone who works with text or data: the small jobs that interrupt real work a dozen times a week. Format a wall of unreadable JSON, convert between CSV and JSON, or diff two versions of a document to see exactly what changed.
The writing and publishing tools cover the rest: count words and reading time, convert Markdown to clean HTML, turn any webpage into Markdown for documentation or AI tools, and generate placeholder text for mockups. The password generator uses your browser's crypto API for genuinely random output.
Every tool here runs entirely client-side. Pasted code, uploaded documents, and generated passwords never touch a server - which is exactly what you want from tools that routinely handle unreleased work and credentials.
