// FIELD NOTES · PRO TIPS
- ◆Install the browser extension — the real value is corrections appearing everywhere you type (email, docs, social), not the web editor.
- ◆Set your goals per document (audience, formality, intent) — suggestions change meaningfully based on these.
- ◆Don't accept every suggestion: Grammarly optimizes for clarity and convention, which can flatten a distinctive voice.
- ◆The tone detector is excellent for emails — check it before sending anything sensitive.
