Frequently asked questions
Is my text uploaded when I use these tools?
No. Counting, case conversion, diffing, and Markdown rendering all run as JavaScript on this page. Paste a confidential draft, get your counts, and nothing ever leaves your browser.
How does the diff work?
It compares the two texts line by line: removed lines show in red with strikethrough, added lines in green, unchanged lines in gray. It's built for prose and code snippets rather than huge files.
Which case should I use for variable names?
Convention depends on the language: camelCase for JavaScript and Java, snake_case for Python and Rust, kebab-case for CSS classes and URLs. The converter produces all of them from the same input.
