Pricing & Limits

Grammarly's AI capabilities vary by plan:

Additionally, Windows and Mac AI Chat supports up to 1,000 chat prompts per day, providing substantial capacity for power users.

Getting Started with Grammarly AI

Creating a Grammarly Account

Grammarly's generative AI features are accessible through a straightforward account setup. The platform offers two main tiers: Free (with 100 generative AI prompts per month) and Pro (with 2,000 prompts per member per month). To begin:

1. Visit Grammarly's website and enter your email address
2. Create a password and verify your email
3. Choose your plan (Free or Pro)
4. Grant browser or application permissions as needed
5. Start writing or uploading documents

The Free tier is ideal for users testing AI-assisted writing, while Pro subscribers benefit from higher prompt limits—approximately 20× more monthly capacity for intensive drafting and revision workflows.

Navigating the Grammarly Editor

Once logged in, you'll interact with Grammarly's core writing interface. The generative AI tools integrate directly into your workflow:

Using AI Rewriting:

• Select any text passage in the editor
• Click the pencil, lightbulb, or paragraph sidebar button that appears
• Review suggested rewrites or enter a custom prompt for specific revisions
• Choose an option or reject all suggestions

Drafting with AI: The "Write with generative AI" tab in the Grammarly Editor helps you start outlines or generate initial drafts. This feature accelerates the blank-page problem by providing structural scaffolding or content seeds you can refine.

Important Limits: Free users receive 100 prompts monthly; Pro subscribers get 2,000 prompts. Each rewrite suggestion or custom prompt counts toward your monthly allocation, so plan accordingly for high-volume writing projects.

Installing Grammarly on Different Devices

Grammarly AI Chat—a dedicated feature on Windows and Mac—expands your capabilities beyond the web editor. Installation steps:

1. Download the Grammarly desktop app from grammarly.com
2. Run the installer and follow on-screen prompts
3. Log in with your account credentials
4. Enable integrations with your preferred applications (Word, Google Docs, email clients, etc.)

On Windows and Mac, AI Chat accepts open-ended prompts for drafting, feedback, and rewriting. Select text in any supported application, choose "Revise with AI," and click "Accept" to integrate generated suggestions. Note that AI Chat operates under a separate limit: 1,000 chat prompts per day.

For mobile users, Grammarly's iOS and Android apps provide core writing assistance and grammar checking, though generative AI features remain most robust on desktop platforms.

Using Grammarly AI for Text Revision

Grammarly's generative AI features allow you to revise, rewrite, and refine your text directly within the editor or through AI Chat. Below are the core workflows for selecting text, applying rewrites, and accepting suggestions.

Selecting Text for Revision

Start by identifying the text you want to improve. In Grammarly Editor, highlight your selection and look for the AI revision interface. A pencil icon, lightbulb, or paragraph sidebar will appear, signaling that generative AI assistance is available. This works across platforms—whether you're using the web editor, browser extension, or native Windows and Mac applications.

For more advanced workflows, open the "Write with generative AI" tab in Grammarly Editor. This feature helps you create outlines, draft new sections, or completely reframe existing passages before you commit them to your document.

Using the AI Rewrite Feature

Once text is selected, you have two options:

1. Choose a suggested rewrite – Grammarly displays multiple AI-generated alternatives tailored to tone, clarity, or brevity.
2. Enter a custom prompt – Type specific instructions (e.g., "Make this more conversational" or "Reduce this to one sentence") for fine-tuned results.

On Windows and Mac, Grammarly AI Chat accepts open-ended prompts for drafting, feedback, and rewriting. You can describe what you need, and the AI generates customized text suggestions within the chat interface.

Accepting AI Suggestions

After reviewing generated text, click "Accept" to apply the rewrite to your document. The original text is replaced instantly, though you can undo the change if needed. This workflow repeats for each section you revise.

Pricing & Limits

Grammarly's generative AI access depends on your plan:

• Free plan: 100 generative AI prompts per month
• Pro plan: 2,000 prompts per member per month

On Windows and Mac, AI Chat enforces an additional daily limit of 1,000 chat prompts per day, ensuring fair resource allocation during peak usage.

For teams managing multiple writers, the Grammarly Enterprise plan scales these limits across your organization while centralizing style guidelines and compliance standards.

Drafting with Grammarly AI

Grammarly's generative AI transforms the drafting process by automating outline creation, draft generation, and content refinement. Whether you're starting from scratch or revising existing work, these tools streamline writing workflows across multiple platforms.

Starting an Outline with AI

The "Write with generative AI" tab in the Grammarly Editor jumpstarts your creative process. Rather than staring at a blank page, you can prompt Grammarly to generate structured outlines tailored to your topic and tone. This feature is particularly useful for long-form content like blog posts, reports, or academic papers.

To access this feature:

1. Open the Grammarly Editor
2. Click the "Write with generative AI" tab
3. Enter your topic or working title
4. Review the suggested outline structure
5. Refine sections or prompt for additional details

Generating Drafts Using AI

Once you have an outline, Grammarly can expand it into full drafts. Select any text in your document and click the pencil, lightbulb, or paragraph sidebar that appears. You'll see suggested rewrites or can enter a custom prompt for more control.

On Windows and Mac, the AI Chat feature offers additional flexibility:

1. Select text you want to revise
2. Choose "Revise with AI" from the context menu
3. Review the generated alternative
4. Click "Accept" to apply or "Reject" to discard

Custom Prompts for Tailored Content

For precise, on-brand content, custom prompts unlock Grammarly's full potential. Instead of accepting default suggestions, you can specify tone, style, audience, and structure—giving AI direction aligned with your goals.

Prompt example: "Rewrite this product description as a conversational email to small business owners, emphasizing ROI and ease of setup."

Usage Limits & Pricing

Grammarly's generative AI features operate under monthly prompt allowances:

• Free plan: 100 generative AI prompts per month
• Pro plan: 2,000 prompts per member per month

The Windows and Mac AI Chat also enforces a daily cap of 1,000 chat prompts per day, preventing exhaustion of monthly quotas in concentrated sessions.

Grammarly Pro starts at $12/month (billed annually) or $30 per member/month billed monthly. For teams, Grammarly Enterprise pricing is custom.

These limits make Grammarly suitable for regular drafting but may require supplementation if you run high-volume content operations. Explore alternative AI writing tools if you need unlimited generations or specialized workflows.

Maximizing Your Grammarly AI Experience

Grammarly's generative AI features empower you to write faster and refine your work with intelligent assistance. Understanding how to use these tools—and their limits—helps you get the most from your subscription.

Understanding Prompt Limits

Grammarly caps generative AI prompts to prevent abuse and ensure service quality. Free plan users receive 100 prompts per month, while Pro subscribers get 2,000 prompts per month per member. If you're a heavy user, this distinction matters: the Free tier allows roughly 3 prompts per day, whereas Pro provides approximately 67 per day.

Additionally, the AI Chat feature on Windows and Mac enforces a separate daily limit of 1,000 chat prompts per day—a buffer that accommodates most workflows without interruption.

Using AI Chat for Feedback

Grammarly's AI Chat streamlines the revision process across desktop platforms. Here's how to leverage it:

1. Select your text in Grammarly Editor, Gmail, or any supported application
2. Click "Revise with AI" from the sidebar options (pencil, lightbulb, or paragraph icon)
3. Choose a suggested rewrite or enter a custom prompt for tailored feedback
4. Click "Accept" to apply the generated text to your document

For starting new projects, use the "Write with generative AI" tab in Grammarly Editor to outline or draft content before refinement.

Exploring Monthly Prompt Options

Your monthly allowance resets on your billing cycle date. To maximize prompts, prioritize high-stakes revisions—cover letters, proposals, emails to leadership—over routine edits. Save lighter tasks like casual messages for manual review.

Upgrading to Pro ($12 per member/month billed annually, or $30 per member/month billed monthly) increases your prompt allocation by 20× (from 100 to 2,000), making it cost-effective if you use AI writing tools regularly. The extra capacity supports content creators, marketers, and professionals managing multiple drafts.

Pro tip: Combine Grammarly's generative AI with its core grammar checking (available on both Free and Pro) for comprehensive writing improvement. Use your monthly prompts strategically—batch similar revision tasks together, and reserve prompts for complex rewrites rather than minor punctuation fixes.

Grammarly AI vs. Other Writing Tools

Comparison with QuillBot

Grammarly and QuillBot both offer AI-powered rewriting, but their approaches differ significantly. QuillBot specializes in paraphrasing and tone adjustment, with a focus on synonym replacement and structural variation. Grammarly's generative AI, by contrast, handles broader tasks—from grammar correction to stylistic enhancement to content generation.

Pricing and Usage Limits:

• Grammarly Free: 100 generative AI prompts per month
• Grammarly Pro: 2,000 AI prompts per member per month ($30 per member/month billed monthly)
• QuillBot Premium: $8.33/month billed annually ($99.95/year), or $19.95 billed monthly

Grammarly's AI Chat on Windows and Mac enforces a separate limit of 1,000 chat prompts per day, allowing power users more flexibility for intensive sessions.

Comparison with ProWritingAid

ProWritingAid excels at detailed style analysis and in-depth reports on readability, repetition, and pacing. Grammarly AI offers faster, more intuitive rewriting through generative capabilities.

Key workflow difference:

1. In Grammarly, select your text
2. Click the pencil, lightbulb, or paragraph sidebar
3. Choose a suggested rewrite or enter a custom prompt
4. Click "Accept" to apply changes

ProWritingAid requires more manual engagement with its report interface, though it provides richer diagnostic data.

For the Grammarly Editor, the "Write with generative AI" tab helps outline or draft from scratch—a feature less developed in ProWritingAid's free tier.

Choosing the Right Tool for Your Needs

Choose Grammarly if:

• You want speed and ease of use with AI-assisted rewriting
• You need real-time corrections across multiple platforms
• Your workflow involves frequent short-form content (emails, social posts)

Choose ProWritingAid if:

• You're writing long-form content and need detailed analytics
• Style consistency and readability metrics matter most
• You can invest time learning its dashboard

Choose QuillBot if:

• Paraphrasing and tone-shifting are your primary needs
• You prioritize simplicity over comprehensive editing

For teams or professionals requiring extensive AI assistance monthly, Grammarly Pro's 2,000 monthly prompts provide better value than QuillBot's unlimited but limited-feature paraphrasing. Start with AI writing tools comparisons if you're evaluating multiple platforms simultaneously.

Conclusion

Recap of Key Features

Grammarly AI delivers practical, real-time writing assistance across desktop and browser platforms. Its generative AI capabilities let you revise text without switching applications—just select content, click the pencil or lightbulb icon, and accept a suggested rewrite or enter a custom prompt. The "Write with generative AI" tab in the Grammarly Editor helps you outline and draft from scratch, while AI Chat on Windows and Mac accepts open-ended prompts for drafting, feedback, and rewriting.

The workflow is straightforward:

1. Select text in any supported application
2. Click "Revise with AI" or the floating toolbar option
3. Review generated suggestions
4. Click "Accept" to apply changes, or iterate with custom prompts

Pricing reflects usage tiers: the Free plan includes 100 generative AI prompts per month, while Pro members get 2,000 prompts per month. For power users, Grammarly's help center lists a separate AI Chat cap. This check confirmed the monthly prompt allowances above, not a daily chat dollar price.

Final Thoughts on Using Grammarly AI

Grammarly AI works best when you already have a draft or clear direction—it augments human judgment rather than replacing it. The tool excels at tone adjustments, formality shifts, and quick rewrites, but always review generated text for factual accuracy and voice consistency. Its integration into your existing workflow (Gmail, Google Docs, Microsoft Word) makes adoption friction-free.

The prompt limits are generous for casual users but may constrain teams handling high-volume content. Consider Pro if you regularly exceed 100 monthly prompts.

Encouragement to Explore AI Capabilities

Don't treat Grammarly AI as a one-trick shortcut. Experiment with custom prompts for specific tasks: "Make this more conversational," "Summarize in one sentence," or "Rewrite for a technical audience." Each experiment teaches you how the model interprets your intent, making future prompts sharper.

If you're evaluating writing assistants, compare Grammarly against other AI Writing Tools to find the right fit for your workflow. Start with the Free tier to test core features, then upgrade to Pro if you need higher prompt allowances and advanced features.
