Grammarly

Grammarly is the writing assistant that shows up wherever you type — email, docs, Slack, forms — and quietly fixes what you got wrong. In 2026 it also became part of something larger: its parent company rebranded to Superhuman, and the browser extension gained an AI assistant that does more than proofread. Grammarly itself keeps its name.

What is Grammarly now?

Grammarly is an AI writing assistant covering grammar, spelling, clarity, tone, conciseness and plagiarism, delivered through a browser extension, desktop apps and mobile keyboards. In late 2025 the company rebranded itself as Superhuman, placing Grammarly in a product family alongside Superhuman Mail and Coda. The rebrand reflected a broader ambition than proofreading — and the clearest expression of it is Superhuman Go, an integrated AI assistant built into the Grammarly browser extension for Chrome and Edge. Superhuman Go, along with connector agents and partner agents, is available to all Grammarly and new Superhuman suite users; it generates writing suggestions, provides email feedback and automates workflows rather than only correcting text.

Key Features

• Ubiquitous corrections: Grammar, spelling, clarity and conciseness anywhere you type, across browser, desktop and mobile.
• Tone detection and adjustment: Rewrite for formality, warmth or directness, which is the feature most business users actually rely on.
• Superhuman Go: An AI assistant inside the browser extension, with connector and partner agents for workflow automation.
• Plagiarism detection: Included on Pro, and the main reason academic users pay.
• Team style guides: Shared brand tone and terminology enforcement on business plans.

Who Should Use Grammarly?

Grammarly is for anyone who writes professionally in short bursts across many applications — the value is coverage, not depth. Students get plagiarism checking and clarity feedback; business users get tone control and consistency. Pro at $12/month is the right tier for most individuals. The $33 per member Superhuman business suite is a different proposition: you are buying Superhuman Mail and the wider productivity stack, not just better writing checks. For long-form generative writing, a general assistant like ChatGPT or Claude will produce better drafts — Grammarly is better at improving text you already wrote.

Pricing

Free covers basic grammar and spelling checks. Grammarly Pro is $12/month, billed as $144 per year, or $360 if billed monthly — unchanged from before the Superhuman rebrand. The Superhuman business suite is $33 per member per month billed annually, or $40 monthly, and bundles Grammarly with Superhuman Mail and other productivity tools. Education and enterprise plans are available separately. Superhuman Go and the connector and partner agents were made available to all Grammarly users at no additional cost through an introductory period.

Pros and Cons

Bottom Line

Grammarly is still the best tool for improving writing you have already produced, and at $12/month Pro is unchanged and easy to justify. The Superhuman rebrand matters mostly if you are evaluating the bundle — Grammarly plus Superhuman Mail at $33 per member is a real productivity suite, not just a writing checker. Use ChatGPT or Claude to draft; use Grammarly to make sure what ships is clean.
