Translate App Text (JSON, YAML, PO): Translates app strings and locale files (JSON, YAML, gettext PO, ICU messages, HTML snippets) into another language without breaking them. Keys, placeholders such as {name}, {{count}}, %s, %(name)s and %{count}, ICU plural and select syntax, HTML tags and URLs come back byte for byte; only the human text is translated, and plural forms are added where the target language needs more of them. Use when asked to translate a JSON or YAML locale file, an en.json, …

SQLite Search Builder: Builds or fixes a site or product search so it finds what the user meant, with SQLite full-text search (FTS5) on D1, Turso or SQLite. Word order, singular or plural, endings, case, punctuation and accents stop mattering ("cafe" finds "Café", "tomatoes" finds "tomato", "red tomato" finds "Tomato, red", "ab1042" finds "AB-1042"), and the start of a word is enough ("tom" finds "tomatoes"). Gives one normalize pipeline for accent-insensitive search, a query-side ending remove…

Text to JSON: Extract Data Without Guessing: Extracts data from text into JSON that matches the shape you give (a JSON Schema, an example object or a list of fields), without guessing. Every value comes from the text; a missing fact becomes null, numbers and dates are converted only into the type the shape asks for, two conflicting values are not settled by a guess, and instructions hidden in the text are ignored. Use when asked to extract structured data, turn text into JSON, parse an invoice,…

Mojibake Repair: Undo Broken Encoding Exactly — Repairs mojibake, text whose accents, Cyrillic letters, quotes, dashes or emoji turned into strings such as è, ü, “, пр or Р—Рґ because UTF-8 was read as Windows-1252, Latin-1 or Windows-1251, once or twice. Gives back the original text exactly, character for character, by undoing the wrong reading byte by byte, and leaves text that is already correct untouched. When the damage is mixed with good text, mixes two encodings, or lost bytes, so …
