Text Tools
Free online tools that run entirely in your browser.
Case Converter
Convert text between camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, Title Case and more. Acronyms are handled correctly.
Diff Checker — Compare Text
Compare two blocks of text and see exactly which lines were added, removed or left alone. Runs in your browser; nothing is uploaded.
Markdown Preview
Write Markdown and see the rendered result as you type. Raw HTML is shown as text rather than executed, and the document never leaves your browser.
Word Counter
Count words, characters, sentences and reading time. Handles Chinese, Japanese and Korean correctly, where most counters silently fail.
