Reverses text three ways: by characters (with proper grapheme-cluster handling so emoji don't break), by word order, or by line order.
Reversing is a common text hack for obfuscation, humor, and linguistic tests. Naive character reversal breaks multi-codepoint emoji like family or skin-tone groups — this tool uses Intl.Segmenter for grapheme-aware reversal.

'Hello, world! 👋' reversed by chars → '👋 !dlrow ,olleH' (emoji intact)'one two three' reversed by words → 'three two one'Lines mode on a numbered list reverses the list orderQ: Are emoji safe? A: Yes
grapheme cluster aware via Intl.Segmenter where available (Chrome/Edge/Safari/modern Firefox).
Q: Does it handle newlines?
A: In chars mode they're characters; in lines mode they're separators.
Q: Can I reverse RTL scripts?
A: The tool reverses the underlying code-point order; rendering reshapes per Unicode bidi rules on display.

Reversed (characters)
Character reversal is grapheme-cluster aware (emoji like 👋 stay intact) via Intl.Segmenter.
Sort lines alphabetically and remove duplicates. Use when cleaning lists; for comparing two texts use text-diff-visual. Input: text lines ≤10MB. Returns sorted unique lines. 100% client-side.
Visual side-by-side diff for two texts with char-level highlights. Use as default diff tool; for similarity score use string-comparison, for JSON use json-diff. Input: two texts ≤10MB. Returns visual diff. 100% client-side.
Obfuscate strings with masking and reversible transforms. Use when hiding PII in demos; for hashing use hash-generator. Input: text ≤10MB. Returns obfuscated text. 100% client-side.
Search and copy emoji with keywords. Use when inserting emoji; for ASCII art use ascii-art. Input: search text. Returns emoji to copy. 100% client-side.
Find and replace text with literal, regex, and case-insensitive modes. Shows replacement count.
Count characters, words, lines, and bytes. Use for quick length checks; for full stats use word-counter. Input: text ≤10MB. Returns counts. 100% client-side.
Compute similarity % and Levenshtein distance between strings. Use for fuzzy match scoring; for visual diff use text-diff-visual. Input: two strings ≤10MB. Returns similarity + distance. 100% client-side.
Count words, characters, and sentences. Get reading time and Flesch score as you type.
