To fix Grammarly not working in Gmail or Google Docs, first check your browser extensions (reinstall Grammarly, remove duplicates, and toggle it OFF/ON) and ensure the toggle in Gmail's bottom‑right corner is ON . For Google Docs, you need Grammarly for Chrome — the Grammarly desktop or Word plugin won't work — and make sure the cursor is inside the document for the green Grammarly dot to appear . That's how to fix Grammarly issues in Gmail/Google Docs in 2026. ✍️🔧
