Easy Tech TutsHow to Add Grammarly to Google Docs Easily 2026
By Impran M NLast checked against official docs
Catching grammar mistakes and awkward phrasing is faster with Grammarly running right inside Google Docs, instead of copying paragraphs into a separate tab and pasting corrected text back. The extension installs once at the browser level and then attaches itself to every Google Doc opened afterward. This guide covers installing it from the Chrome Web Store, signing in, and using both the underline-based suggestions and the AI assistant panel once it's live in your document.
01Find Grammarly in the Chrome Web Store
Open the Chrome Web Store and search for Grammarly. The official listing, Grammarly: AI Writing Assistant and Grammar Checker App, carries a Featured badge, a rating around 4.5 stars from more than 40,000 reviews, and tens of millions of users, enough to confirm it's the real one and not a lookalike. The listing previews what you're installing: screenshots of inline suggestions and AI support embedded directly into a document.
02Install and sign in
Click Add to Chrome, confirm the permissions prompt, and the extension installs immediately. You're redirected to log into an existing Grammarly account or create one. Sign-in matters here: suggestions and any saved writing goals tie to the account, not the browser, so switching computers just means signing in again.
03Open a Google Doc and look for the floating icon
Open any document and Grammarly attaches to it automatically, no separate step needed inside Docs itself. Place your cursor or start typing and a small green icon appears near the text. That icon is the entry point to everything Grammarly offers on the page, from quick grammar fixes to the full writing assistant.
04Review inline grammar and spelling suggestions
As Grammarly scans the text, it underlines words and phrases it has suggestions for. Clicking an underlined section pops up the specific issue, a misspelling, a punctuation error, an awkward phrase, along with a one-click fix you can accept or dismiss. Nothing changes until you say so.
05Open the assistant panel to rewrite, set your voice, and adjust goals
Click the floating icon to open the full panel, which goes beyond simple corrections. Set your voice calibrates how generated or edited text should sound, and a "What do you want to do?" section offers shortcuts like Improve it, Identify any gaps, and More ideas, plus a free-text box for a specific instruction. A school essay and a marketing email don't call for the same tone, so use this panel's voice and goal settings per document: tell Grammarly what you're writing and who it's for, and its suggestions shift accordingly, flagging casual phrasing in a formal document or stiff wording in something meant to sound conversational.
Frequently asked questions
Is Grammarly free to use with Google Docs?
Yes, for the basics. The free plan checks grammar and spelling and includes 100 AI prompts a month for tools like Improve it. Full-sentence rewrites, tone rewriting, and a higher prompt allowance require the paid Plus plan.
Does Grammarly work on Google Docs mobile?
The browser extension only works on desktop; Grammarly offers a separate mobile keyboard app for phone and tablet use.
Can I adjust the writing tone Grammarly checks for?
Yes, the assistant panel's Set your voice option and goal settings let you tailor suggestions to a specific audience and formality level.
Will Grammarly slow down my document?
It shouldn't noticeably affect performance for typical documents, though very large files may see a slight lag while suggestions load.
How do I know I'm installing the real Grammarly extension?
Check for the Featured badge, the verified Grammarly publisher name, and a large, established rating count on the Chrome Web Store listing before installing.
Why does my document show a Superhuman icon instead of Grammarly's?
Grammarly's own support documentation notes that accounts with Superhuman Go activated see a Superhuman logo and tab in place of Grammarly's, since Grammarly is now part of Superhuman. The underlying suggestions work the same way.
Sources and last check
Install flow and panel screens come from a recorded Chrome and Google Docs session. Re-checked against Grammarly's own support articles and pricing page in September 2026, which corrected the paid tier's current name (Plus, not Premium), added the free plan's 100-prompt monthly cap, and surfaced the Superhuman rebrand some accounts now show.

I've been hooked on technology for as long as I can remember — especially the new tools and AI apps that seem to land every other week. Easy Tech Tuts is where I write up whatever I've just worked out: I do the task in the real product, record the screen, and turn it into the guide I wish I'd found first.
