AllCoreKit's text tools handle the everyday text-processing tasks that developers, writers, and content creators reach for constantly. Whether you're counting words before hitting a platform limit, converting a slug for a CMS, cleaning up whitespace from a PDF export, comparing two document drafts, or reversing a string during a code review — every tool here runs instantly in your browser, processes your text locally, and never sends a character to a server.

Word Counter

Popular

Real-time count of words, characters, sentences, paragraphs, and reading time.

e.g. Check word count before submitting an academic essay with a strict limit

Case Converter

Popular

Convert text to uppercase, lowercase, title case, camelCase, snake_case, and more.

e.g. Convert a function name from snake_case to camelCase when refactoring code

Remove Duplicate Lines

Paste text and instantly remove duplicate lines, with options for case sensitivity.

e.g. Deduplicate an email list merged from multiple CRM exports

Text Reverser

Reverse your text character-by-character or word-by-word instantly.

e.g. Generate reversed placeholder text for RTL layout testing

Slug Generator

Convert any text into a clean URL-friendly slug with your choice of separator.

e.g. Generate a blog post permalink from a headline before publishing

Whitespace Cleaner

Remove extra spaces, trim lines, delete blank lines, flatten paragraphs, and replace tabs — all with live preview.

e.g. Clean up text pasted from a PDF that has extra line breaks at every column wrap

Text Diff

Compare two texts and highlight added, removed, and unchanged content at word or character level.

e.g. Compare two versions of a legal contract to identify what was changed between drafts

Sort Lines

Sort any list of text lines alphabetically, numerically, by length or complexity. Remove duplicates and customize sorting options instantly.

e.g. Alphabetize a list of names or titles for a directory or index

Full-width Converter

Convert ASCII characters to Unicode full-width (abc123) and back — useful for styled text.

e.g. Style a social media bio or username with the aesthetic vaporwave look

Binary ↔ Text

Convert text to binary (0s and 1s) and back — both directions, with live validation.

e.g. Convert a message to binary for a computer science assignment on character encoding

Morse Code Converter

Convert text to Morse code and back, with audio playback and adjustable speed.

e.g. Translate a short message to Morse and play it back to practise recognising the codes by ear

Split Text

Split any text into chunks by line, sentence, word count, character count, or a custom delimiter.

e.g. Split a long article into sentence-sized chunks to build an LLM prompt that processes each sentence individually

Replace Text

Apply multiple find-and-replace rules simultaneously, with regex and whole-word support.

e.g. Normalise a data export by replacing semicolons with commas and stripping extraneous quote pairs in one pass

Text to ASCII Codes

Convert text to ASCII decimal, hex, binary, or octal codes instantly. See the ASCII value of every character.

e.g. Decode a space-separated list of decimal ASCII codes encountered in a CTF challenge or encoding puzzle

Shuffle Lines

Randomly shuffle the lines of any text instantly. Perfect for randomizing lists, quiz questions, or dataset rows.

e.g. Randomise the order of quiz questions or flashcard prompts before a study session

Text Centering

Center, left-align, or right-align text within a fixed width. Perfect for formatting CLI output, README banners, and plain text documents.

e.g. Centre a title or section heading within an 80-column README or documentation file

Text Repeater

Repeat any word, phrase or string multiple times with custom separators. Generate repeated text instantly.

e.g. Generate large amounts of placeholder text for UI/UX testing and mockups

Line Numbering

Add line numbers to any text with custom start number, step, separator and zero-padding options.

e.g. Add line numbers to code snippets to make them easier to reference in technical guides.

Emoji Picker

Popular

Browse, search and copy emojis easily. Get the Unicode code point, HTML entity and CSS values for any emoji instantly.

e.g. Quickly find and copy emojis for social media posts, emails, or blog articles

Text Corruptor

Add realistic random errors and typos to any text. Control error intensity and types to simulate human mistakes, test spell checkers, or create corrupted text effects.

e.g. Generate test data to evaluate the accuracy of a spell checker or autocorrect algorithm
