Grammarly is still the best real-time writing assistant in 2026, and the one tool on this site we'd recommend to almost anyone who types for a living. Its edge isn't the smartest AI — it's that it sits inside every app you use, from Gmail to Google Docs to Slack, correcting and rewriting as you go. The generative features have caught up to the chatbots, and new "Superhuman Go" agents add genuine capability. It's not the tool for drafting long-form marketing content from scratch — that's Jasper's job — but for polishing everything you write, nothing beats it.
Verdict: The most useful writing tool to have installed — ubiquitous, fast, and now genuinely capable at rewriting and generation. A polisher, not a long-form drafting machine.
Best for: professionals and students who write across many apps every day.
What is Grammarly?
Grammarly is an AI writing assistant that checks grammar, spelling, clarity, and tone, and rewrites or generates text on demand. What separates it from a chatbot is reach: it runs as a browser extension, desktop app, and mobile keyboard, so it works in basically every text box you touch rather than living in one tab.
In 2026 it's more than a grammar checker. It rewrites sentences for tone, generates drafts and replies with its generative AI, adapts to a set style guide, and — new this year — connects to agents that can pull context and take action across your apps.
Key features
Real-time correction everywhere
This is the core and still the best reason to use it. Grammarly underlines issues as you type in Gmail, Docs, LinkedIn, Slack, Word, and thousands of other sites, with one-click fixes. The suggestions are fast, accurate, and unobtrusive, and the "everywhere" coverage is what no chatbot replicates.
Tone detection & rewrites
Grammarly reads the tone of what you've written — confident, friendly, formal — and can rewrite a sentence or a whole message to shift it. For email and professional messaging this is the feature people actually keep using: turn a blunt draft into something diplomatic without rewriting it yourself.
Generative writing
Grammarly's generative AI drafts text from a prompt, shortens or expands passages, and composes replies. It's solid for emails, summaries, and short-form work. It's not built to out-write a dedicated long-form tool on a 2,000-word blog post, but for the quick "help me write this" moments inside your inbox, it's right there.
The Superhuman rebrand
Worth knowing: Grammarly's parent company rebranded to Superhuman in late 2025, uniting Grammarly, the Coda workspace, and Superhuman Mail under one brand as an AI-native productivity platform. The Grammarly writing assistant still exists and is still called Grammarly — you didn't lose anything.
What's new is Superhuman Go: connector and partner agents available on the Chrome and Edge extensions (with Mac and Windows following) that let Grammarly pull data and coordinate actions across your apps, not just fix text. It's the company's bet that writing assistance becomes agent assistance. If you also live in your inbox, see our Superhuman review for the mail side of the platform.
Pricing
Grammarly has a genuinely useful free plan and a single main paid tier.
| Plan | Price | What you get |
|---|---|---|
| Free | $0 | Grammar, spelling, basic tone, 100 AI prompts/month |
| Pro | $12/mo annual ($30 monthly) | Unlimited rewrites, full generative AI, style guide, brand tone, snippets, team analytics |
| Enterprise | Custom | SSO, SCIM, managed mode, BYOK encryption, DLP, audit logs, admin controls |
The gap between monthly ($30) and annual ($12/mo, billed $144/year) is huge, so only pay monthly if you're testing. The free plan's 100 AI prompts a month is enough for casual use; Pro is the one to get if you rewrite and generate weekly. Full breakdown in our Grammarly pricing guide.

Who it's for
Get Grammarly if you write emails, docs, and messages all day and want them cleaner without effort — it's the highest-value writing tool you can install, and the free plan proves it before you pay. Look elsewhere if your main job is producing long-form marketing content at scale; a tool like Jasper or Copy.ai is built for that. Many people run both: Grammarly to polish, a dedicated writer to draft.

Frequently Asked Questions
Is Grammarly worth it in 2026?
Yes for anyone who writes across many apps and wants real-time correction everywhere. Grammarly Pro at $12/month annually is worth it if you use the tone, rewrite, and generative features weekly. The free plan is enough for basic grammar and spelling.
How much does Grammarly cost?
Free is $0 with 100 AI prompts per month. Pro is $12/month billed annually, $20/month quarterly, or $30 month-to-month. Enterprise is quote-based and adds SSO, SCIM, and admin controls.
Did Grammarly change its name to Superhuman?
The parent company rebranded to Superhuman in late 2025, uniting Grammarly, Coda, and Superhuman Mail. The Grammarly writing assistant still exists under the Grammarly name; Superhuman Go adds connector and partner agents to its browser extension.
Is the free version of Grammarly good enough?
For grammar, spelling, and basic tone, yes. The free plan also includes 100 AI prompts a month. If you rely on rewrites, the full generative features, a style guide, or brand tone, you'll want Pro.
Can Grammarly write full articles?
It can draft and expand text, but it's designed as a polisher and short-form generator, not a long-form content engine. For 2,000-word marketing articles, a dedicated tool like Jasper or Writesonic produces stronger first drafts.
Does Grammarly work in Google Docs and Word?
Yes. Grammarly runs in Google Docs via the browser extension and integrates with Microsoft Word, plus Gmail, Outlook, Slack, LinkedIn, and thousands of other sites through its extension, desktop app, and mobile keyboard.
Is Grammarly better than ChatGPT for writing?
They do different jobs. ChatGPT is a better generative drafting tool; Grammarly is a better real-time editor that works inside every app. Many writers use ChatGPT to draft and Grammarly to catch errors and adjust tone as they type.
What is Superhuman Go?
Superhuman Go is a set of connector and partner agents on Grammarly's browser extension that pull context from your apps and coordinate actions, moving Grammarly from a text tool toward an agent that can help with tasks, not just corrections.
