Text tools

Find and strip the characters that are in your text but not on screen. Everything runs in your browser.

• Invisible Character RemoverFind and remove the characters hiding in your text: zero-width spaces, invisible Unicode, bidirectional overrides and lookalike letters.
• Social Media Character CounterCount a post the way each platform counts it: X link weight, grapheme clusters for Instagram, UTF-16 for TikTok, GSM-7 SMS segments.
• Case Converter for Titles, Sentences & CodeAn editorial rules engine, not a toUpperCase call: AP and Chicago small-word tables, acronyms kept as written, brands like iPhone protected, plus camel.
• URL Slug GeneratorA documented RFC 3986 pipeline: pre-map what NFKD will not decompose, strip marks, transliterate Devanagari and Tamil, truncate at a word boundary.
• Find and Replace with RegexThe replacement half of regex: capture groups, a literal dollar that silently eats text, lookahead, the missing g flag, and a dry run before applying.
• Text Diff CheckerCompare two texts line by line or word by word, with normalisation first so CRLF, tabs and a BOM do not read as changes, plus unified diff output.
• Number to Words (Indian System)Both directions, both numbering systems: lakh, crore, arab and kharab beside million and billion, a proper cheque line, and a words-to-number verifier.
• Readability Checker & Text StatisticsFive formulas with their assumptions shown, plus word, sentence and reading-time counts. Honest about a syllable heuristic wrong on 5-10% of words.
• CSV CleanerParses RFC 4180 by hand, detects the delimiter by column-count consistency not frequency, reports ragged rows by index, keeps destructive fixes off.
