9 pieces

All topics
  • ResourceTool
    String Case ConverterConvert any string into camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, Title Case, Sentence case, or flat upper/lower. Renaming things across a codebase reads faster when every variant is one click away.
  • ResourceTool
    Slug GeneratorTurn any text into a URL-safe slug. Strips diacritics, collapses whitespace, picks - or _ separators. Authoring titles for blog posts, projects, or storage keys without hand-rolling the same regex every time.
  • ResourceTool
    Lorem IpsumGenerate paragraphs, sentences, or words of placeholder text. Seeded so the output is stable across rerolls. Filling a layout while real copy is still pending — boring tools should boot instantly.
  • ResourceTool
    Word & Character CounterLive count of words, characters, lines, sentences, paragraphs, and an estimated read time. Trimming meta descriptions, social posts, or tweet drafts to a target length.
  • ResourceTool
    Regex TesterLive pattern + flags against a sample buffer. Highlighted matches, capture groups inspector, error messages. The fastest way to know whether your regex actually matches what you think it does.
  • ResourceTool
    Text DiffLine-level diff between two text blocks. LCS-based; additions, deletions, and matches highlighted. Pull-request review without leaving the page — paste before and after, see the change.
  • ResourceTool
    Morse CodeTwo-way text ↔ Morse converter. International alphabet, `/` between words, single space between letters. The kind of utility that's only needed twice a year — but really needed those two times.
  • ResourceTool
    ASCII ArtRender short strings as 5-row block-font ASCII art. Pick the fill character; copy as plaintext. Banners for terminal headers and README hero blocks, without a node CLI install.
  • ResourceTool
    Roman Numeral ConverterTwo-way Roman ↔ decimal converter. Validates canonical form (no double subtractive, no rank repetition over 3). Stamping a copyright year is easy; reading MMXXVI in someone else's headline is less so.
