Text Tools

ArrayKit's Text tools cover the everyday writing and string work developers, writers and testers do dozens of times a day. Jot things down in the Online Notepad, which saves automatically in your browser, or have any passage read aloud with Text to Speech using the voices on your device. Copy any emoji with one click from the Emoji Picker, then count words, characters, sentences, lines, UTF-8 bytes and an approximate token estimate with the Word and Character Counter. The Case Converter switches identifiers between camelCase, snake_case, kebab-case and PascalCase, and the Slug Generator turns a title into a clean, URL-safe slug. Stuck on a word game? The Word Unscrambler turns a rack of letters into every valid word, with blank-tile wildcards, filters and Scrabble-style scores. Need placeholder copy or characters? The Lorem Ipsum Generator produces paragraphs, sentences or words on demand, the Random Name Generator creates first and last names by region and gender, and the Mock Data Generator creates fake JSON with names, emails, UUIDs and dates. Everything runs in your browser: your text is processed locally on your device and nothing is uploaded.

Frequently asked questions

What can I do with ArrayKit's Text tools?
Write and keep notes in the Online Notepad, listen to text with Text to Speech, copy emoji, count words and characters, convert case, build slugs, unscramble letters into words, generate random names, lorem ipsum and mock JSON. Each tool opens in its own page and works on whatever you paste or type, with nothing uploaded.
Which text tool should I use to count words and characters?
Use the Word & Character Counter. Paste or type your text and it shows live word, character, sentence, line and UTF-8 byte counts plus an approximate token estimate and reading time, with an optional top-words frequency list.
Can these Text tools reformat identifiers and URLs?
Yes. The Case Converter rewrites identifiers between camelCase, snake_case, kebab-case, PascalCase and more, and the Slug Generator turns titles into clean URL slugs with a hyphen or underscore separator, accent stripping and optional stop-word removal, including a batch mode.
Are these Text tools safe to use with sensitive content?
Yes. Every Text tool runs entirely in your browser. Your input is processed locally on your device and nothing is uploaded to a server, so even sensitive drafts, prompts and identifiers never leave your machine.
Do the Text tools work offline?
Once the page has loaded, the tools run on your device in your browser, so word counting, case conversion, slug generation, word unscrambling, lorem ipsum and mock-data creation keep working even if your connection drops.
Can I generate placeholder names and test data with these tools?
Yes. The Random Name Generator creates first and last names by region and gender for characters and placeholders, the Lorem Ipsum Generator produces filler paragraphs, sentences or words for mockups, and the Mock Data Generator creates fake JSON records — names, emails, UUIDs, dates and prices — for seeding databases, populating prototypes and stubbing API responses.
