Choosing the right tool
Text tools solve the small jobs that come up all day. A word counter checks a draft against a limit and estimates reading time. A case converter changes a heading from title case to a variable name in camelCase or snake_case, which saves retyping. A diff checker shows exactly what changed between two versions of a document, line by line or word by word, so a careless edit does not slip through.
A regular expression tester helps when you need to find or validate a pattern, such as an email address or a date, and shows each match as you type so you can fix the pattern before you use it in code. Regular expressions are powerful and easy to get subtly wrong, which is why seeing the matches live is so useful.
Everything runs in your browser, so drafts, contracts and source code you paste are never uploaded or stored anywhere.
Frequently asked questions
- How is a word count worked out?
- Words are found with the Unicode rules built into your browser, so contractions, accents and non-Latin text count correctly. Different programs treat hyphens and numbers slightly differently, so counts can vary by a few words.
- What can I use a diff checker for?
- Comparing two versions of a contract, an article or a piece of code to see precisely what was added, removed or changed.
- Are my texts stored anywhere?
- No. They are processed in your browser. Some tools remember your last input on your own device so it is there next time, and you can clear it at any time.
