About Text Tools
These are the small text jobs that interrupt real work. A heading needs to be Title Case. A variable name needs to be camelCase. A client asks how long the copy is. Two versions of a document exist and nobody remembers what changed between them.
None of it is difficult, but doing it by hand is slow and error-prone, and pasting a draft into an unknown website is a bad habit when the draft is unpublished or confidential. Everything here runs locally in your browser, so the text you paste stays in the tab.
Which tool do you need?
- Changing capitalisation
- The Case Converter handles UPPERCASE, lowercase, Title Case and Sentence case for writing, plus camelCase, PascalCase, snake_case and kebab-case for code. Pick the code conventions by language: camelCase for JavaScript variables, snake_case for Python, kebab-case for CSS classes and URLs.
- Measuring length
- The Word Counter gives words, characters with and without spaces, and an estimated reading time. Useful against a word limit, and for checking whether a meta description will be truncated.
- Finding what changed
- The Diff Checker compares two texts side by side and highlights the differences. Faster than reading both, and it catches the single changed number that the eye slides past.
- Making a URL
- The Slug Generator turns a title into a clean lowercase, hyphenated slug — accents folded, punctuation dropped, spaces converted.
- Writing Markdown
- The Markdown Preview renders as you type, so you can check a README or a blog post before committing it.
- Making a banner
- The ASCII Art Generator turns text into block letters for terminal splash screens, code comments and READMEs.
For anything you plan to publish, the Word Counter and the Slug Generator are worth running together: one tells you whether the piece is the right length, the other gives you the URL it should live at.
Frequently asked
Is my text sent anywhere?
No. Every text tool runs in your browser. Nothing you paste is transmitted, which is worth knowing before you drop a draft contract or an unpublished article into a random online word counter.
Why do two tools give different character counts?
Usually spaces. Most publishers and academic limits count characters including spaces; some social platforms count them excluding spaces. The Word Counter shows both, so use whichever the place you are submitting to asks for.
How is reading time calculated?
From word count at roughly 200–250 words per minute, which is the usual range for adults reading ordinary prose. It is an estimate, not a measurement — dense technical writing runs slower and light copy runs faster.
What is a URL slug and why does it matter?
The human-readable part of a web address after the domain. A short slug made of real words is easier to read, easier to share, and gives search engines a clearer signal than a string of numbers. The Slug Generator strips accents, punctuation and spacing for you.
