- Linguistics exercises, estimating syllable counts and readability, solving word puzzles with vowel constraints, and quick classroom statistics on writing samples.

- Yes. This tool runs entirely in your browser using client-side JavaScript — nothing you type is transmitted to, logged by, or stored on any server. You can safely process confidential text, tokens, or code.
