Superhuman Go is built by the makers of Grammarly. It works inside your Grammarly extension and uses the same account, so you get Go alongside Grammarly’s writing features—no separate app, no separate subscription. Think of Go as the AI learning partner that joins your existing Grammarly workflow.

Yes. You can use Superhuman Go for free with a Grammarly account. Some advanced capabilities—like unlimited AI Detector checks and Plagiarism Checker—are part of Grammarly Pro. You can activate Go without entering a credit card.

Go is built as a learning partner, not a shortcut. It explains concepts, helps you refine your own writing, and surfaces sources—but it doesn’t generate finished work for you. Every school has its own AI policies, so check yours. Authorship, included with Grammarly, keeps a transparent record of how AI helped, so you can show your professor exactly what you wrote.

Two big differences. First, Go works inside the tools you already use for school—Google Docs, Microsoft Word, your LMS, your browser—instead of pulling you into a separate tab. Second, Go is built for academic work specifically: It understands assignment context, preserves your voice, and pairs with the Grammarly authenticity suite (AI Detector, Authorship, Plagiarism Checker, Citation Finder), so you can submit with proof. ChatGPT is a general-purpose chatbot. Go is a learning partner built for school.

Go is available through the Grammarly extension for Chrome and Edge, plus the Grammarly desktop app. Once activated, it shows up across the sites and apps you already use—Google Docs, Microsoft Word, your LMS (including Canvas), and most websites where you read or write online.

Grammarly processes only what’s needed to give you a response for the task at hand. Your data isn’t sold. And with Authorship, you control exactly what’s recorded about your writing process and what you choose to share. See Grammarly’s Privacy Policy and Trust Center for more details.
