Grammarly installs as a browser extension or desktop app and watches what you type wherever you type it — email, documents, forms, chat. It underlines what it would change as you go; you click a suggestion to accept it, or dismiss it and keep writing.
A writing assistant that works inside the applications you already use rather than in its own window.
Free for spelling, grammar, and basic tone; paid for rewrites, tone adjustment, and detection features.
Now one product within a company that renamed itself Superhuman — the writing tool is still called Grammarly.
Best understood as an always-on layer, not a tool you open.
The company is now called Superhuman. It renamed itself on 2025-10-29, uniting the writing tool with an email client and a workspace product. You will see Superhuman branding and prompts for other products. The writing assistant you came for is still Grammarly.
The free plan covers spelling, grammar, and tone signals plus a limited monthly allowance of AI prompts — roughly a hundred.
The main paid tier is priced per person, cheaper if you pay annually, and raises the AI prompt allowance many times over. There is no published top-up if you exhaust it.
Decide where it runs before you install it. The extension can see what you type on the sites it is enabled for, and that choice is more consequential than any setting inside the product.
The company states it does not sell user content or use it to train third-party models, holds recognised security certifications, and performs basic checks on your device rather than in the cloud. Taken on its own that is a reassuring posture, and there is no reason to doubt it.
The exposure is a different shape: surface area. This is software with read access to text as you type it, across whatever sites and apps you enable. That is not a claim about misuse — it is a description of what the product is. The relevant question is not whether the vendor is trustworthy, but whether you want any third party positioned to read everything typed into your banking portal, your medical records, or your employer's internal systems.
Restricts the extension to the sites where you actually want help.
Why this one: The default is broad. Narrowing it deliberately is the highest-value five minutes you will spend with this tool.
Tweak: Start with banking, health, and work systems disabled, then add exceptions as you find you want them.
Drafts the email somewhere Grammarly is enabled and reads the tone reading it shows before you press send.
Why this one: Tone detection is more useful than grammar checking for most adults, and almost nobody uses it deliberately.
Tweak: If the tone reading surprises you, that is the point. Rewrite before you send, not after they reply.
Dismisses a suggestion you disagree with instead of accepting it, and keeps your original wording.
Why this one: Builds the habit of treating suggestions as opinions rather than corrections, which is what keeps your writing sounding like you.
Tweak: Pay attention to how often it wants to remove a deliberate stylistic choice. Those are the ones to keep.
Keeps track of how many AI prompts you use in a month against the free plan's small allowance, without changing how you write.
Why this one: Free and paid tiers differ mostly in this number, so knowing your real usage tells you whether upgrading would change anything.
Tweak: If you never approach the free limit, the paid tier is buying you features rather than capacity — decide on that basis.
