What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

• generate_word_search

  Create a word-search puzzle (sopa de letras) from a list of words. Puzzles up to 10x10 with at most 10 words are free and unlimited; bigger ones use the free puzzles each client gets. Keeps native letters (Ñ, Ç, Ã, Ä, ẞ, È…) as one cell each. Returns the grid, where every word is

• fill_word_search

  Completes a word search: takes the grid from generate_word_search (empty cells are "-") and fills them with random letters in the chosen language, with accents on or off. Letters follow how common they are in that language. Pass the puzzle's words so the filler never creates an e

• stylize_text

  Turns text into Unicode styles for social media bios and posts: bold, italic, script, fraktur, monospace, circled, squared, fullwidth, small caps, strikethrough, underline and more (22 styles). Accents are kept: an accented letter becomes its styled base letter plus the combining

• list_styles

  The Unicode text styles stylize_text offers, with the id to pass, an English name and a category (bold-italic, sans, script, gothic, mono, enclosed, decoration, other).

• sudoku

  Creates a sudoku with exactly one solution. Returns puzzle (0 = empty cell) and solution. Sizes 4, 6, 9 (default), 12 and 16; difficulty 1 easy (most clues) to 4 expert. Free, no usage limit. The same seed gives the same sudoku.

• solve_sudoku

  Solves a sudoku grid (0 = empty cell; sizes 4, 6, 9, 12, 16) and says whether the solution is the only one. Free, no usage limit.

• list_languages

  Languages Lettras supports, with the native letters each one adds to its grid alphabet.
