How to Add Grammarly to Google Docs Easily 2026

Open the Chrome Web Store and search for Grammarly. The official listing — Grammarly: AI Writing Assistant and Grammar Checker App — is easy to confirm as legitimate: it carries a Featured badge, a 4.5-star rating from over 43,000 reviews, and a user count in the tens of millions. The store listing itself previews what you're installing, showing screenshots of inline clarity suggestions and AI support embedded directly into a document.

Click Add to Chrome, confirm the permissions prompt, and the extension installs immediately. You're then redirected to log into an existing Grammarly account or create a new one — this sign-in matters because Grammarly ties its suggestions and any saved writing goals to your account rather than to the browser alone, so switching computers just means signing in again rather than reconfiguring anything.

Open any document, and Grammarly attaches to it automatically — no separate step needed inside Docs itself. As you place your cursor or start typing, a small green icon appears near the text, which is your entry point into everything Grammarly offers on that page, from quick grammar fixes to its broader writing assistant.

As Grammarly scans your text, it underlines words and phrases it has suggestions for. Clicking an underlined section pops up the specific issue — a misspelling, a punctuation error, or an awkward phrasing — along with one-click fixes you can accept or dismiss individually, so you stay in control of every change rather than accepting a blanket correction pass.

Click the floating icon to expand Grammarly's full panel, which goes well beyond simple corrections. It offers a Set your voice option for calibrating how your generated or edited text should sound, plus a "What do you want to do?" section with shortcuts like Improve it, Identify any gaps, and More ideas, alongside a free-text box where you can type a specific instruction for how you want a passage rewritten.

Not every document needs the same voice — a school essay and a marketing brochure call for different levels of formality. Use the panel's voice and goal settings to tell Grammarly what you're writing and who it's for, and its suggestions shift accordingly, flagging casual phrasing in a formal document or overly stiff wording in something meant to sound conversational.
