Questions
Is my writing sent anywhere?
No. A small language model runs in your browser — the same ~500 MB model as the AI Summarizer, downloaded once and cached.
How good is it?
It catches most spelling, grammar and punctuation mistakes in everyday writing. Always review the highlighted changes.
Which languages?
Works best in English; it also handles major European and Asian languages reasonably.
