Text Tools

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
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
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
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
