CraftMyLetter vs Grammarly AI: Which Writes Better Cover Letters?

If you're choosing between CraftMyLetter and Grammarly AI for your cover letter, here's the short answer: CraftMyLetter is purpose-built for letters and generates them from scratch, while Grammarly is a general writing assistant that helps you polish and refine existing drafts. The best tool depends on where you are in the writing process. If you need a complete letter written quickly, CraftMyLetter wins. If you've already drafted something and want to improve it, Grammarly AI shines.

Both tools use artificial intelligence, but they solve different problems. Let's break down how they compare so you can pick the right one for your job search.

What Is Grammarly AI?

Grammarly AI is a writing assistant owned by Grammarly, the company famous for checking grammar and spelling. Over the past few years, Grammarly has expanded beyond simple grammar correction into a full-featured ai cover letter writer powered by machine learning.

Grammarly's AI features include:

Grammar, spelling, and punctuation checks
Tone adjustments (confident, professional, friendly, formal)
Clarity and clarity improvements
Plagiarism detection
AI-powered writing suggestions and rewrites

Grammarly works as a browser extension, web editor, and mobile app. You write or paste text, and Grammarly suggests improvements in real-time. The free version catches basic grammar issues; the Premium subscription ($12/month) unlocks advanced AI features like tone detection, clarity enhancements, and full rewrites.

Grammarly is a general-purpose writing tool. It's equally useful for emails, essays, LinkedIn posts, and cover letters. It doesn't specialize in any one type of writing.

What Is CraftMyLetter?

CraftMyLetter is an ai cover letter writer specifically designed for generating formal letters from scratch. The platform uses AI to create personalized cover letters, resignation letters, thank-you letters, and 26+ other letter types in seconds.

Here's how CraftMyLetter works:

You select your letter type (cover letter, resignation letter, reference request, etc.)
You answer a few questions about your situation, skills, and the position
CraftMyLetter's AI generates a complete, ready-to-use letter
You can edit, customize, and download the letter as a PDF or Word document

CraftMyLetter is laser-focused on letter generation. It's not trying to be a general writing assistant. It's built specifically for people who need formal letters written quickly and professionally.

The platform offers:

Free tier: 2 letters per month
Starter plan: $4.99 one-time (10 letters)
Plus plan: $9.99 one-time (25 letters)
Pro plan: $17.99 one-time (50 letters)

All plans are one-time purchases, not recurring subscriptions.

Feature Comparison: CraftMyLetter vs Grammarly AI

Letter Generation: From Scratch vs. Polish

The biggest difference between these tools is the starting point.

CraftMyLetter generates a complete letter from scratch. You don't write anything. You answer questions about your background, the job, and your goals, and the AI produces a full letter you can use immediately. This is perfect if you're staring at a blank page and have no idea where to start.

Grammarly AI assumes you've already written a draft. It helps you refine and improve what you've written. You paste in your cover letter, and Grammarly suggests ways to make it sound more confident, professional, or clear. If you have zero words on the page, Grammarly won't help you generate them.

Letter Types: Specialized vs. General

CraftMyLetter offers 26+ specialized letter types: cover letters, resignation letters, thank-you letters, reference requests, follow-up emails, apology letters, and many more. Each template is customized for that specific letter type, so the AI understands the context and tone you need.

Grammarly AI treats all writing the same. There's no "cover letter mode" or "resignation letter mode." You get tone adjustments (formal, professional, confident), but the AI doesn't know whether you're writing a cover letter or an email to your landlord.

Customization: Context-Aware vs. Surface-Level

CraftMyLetter digs into your specific situation. It asks:

What's the job title and company?
What industry are you in?
What are your top skills?
Why do you want this job?
What's your experience level?

The AI uses this context to generate a letter that's tailored to your situation, industry, and the specific role. The tone, language, and focus shift based on what you tell it.

Grammarly AI adjusts tone and clarity, but it doesn't know your context. It can't make your cover letter more specific to the job posting or industry because it's a general writing tool. It polishes what you write, but it doesn't understand the unique angle you're trying to take.

Speed: 30 Seconds vs. Hours

CraftMyLetter generates a complete, usable letter in about 30 seconds. After answering a few questions, you have a draft you can send immediately (or lightly edit for your preferences).

Grammarly AI requires you to write first. Depending on how fast you type and how clear your thinking is, writing a cover letter from scratch can take 30 minutes to 2 hours. Then you run it through Grammarly to polish it. Total time: significantly longer.

Pricing: One-Time vs. Subscription

CraftMyLetter uses a one-time payment model:

Free: 2 letters per month
$4.99: 10 letters (one-time)
$9.99: 25 letters (one-time)
$17.99: 50 letters (one-time)

Once you pay, you own those letters forever. No recurring charges, no monthly fees.

Grammarly AI is a subscription:

Free: Basic grammar checking
Premium: $12/month (or $144/year if you prepay)

If you use Grammarly every month, it costs $144+ per year. If you only need it for a few cover letters, you're paying for features you won't use.

Best For: Different Use Cases

CraftMyLetter is best for:

People who need a cover letter written right now
Non-native English speakers who want a professionally written starting point
People who've never written a cover letter and aren't sure where to begin
Job seekers who are applying to many positions and need speed
Anyone who wants a letter generated from context and customization, not just polished

Grammarly AI is best for:

People who enjoy writing and want to refine their own voice
Writers who have a draft and want professional polish and tone adjustments
People writing many types of content (emails, essays, reports) who need a general-purpose assistant
Those who want real-time, continuous feedback as they write

When to Use Grammarly AI

Grammarly AI is genuinely useful for cover letters—but only in specific situations.

If you've already written a cover letter draft and you want to:

Fix grammar and spelling mistakes
Make your tone more confident or professional
Ensure consistency in your writing style
Check for clarity issues

Then Grammarly is a solid choice. It's been around for years, it's trusted by millions, and it does catch real problems that could hurt your chances.

Grammarly AI is also excellent if you're already a Premium subscriber for other writing projects. In that case, you already have access, and using it on your cover letter is free (beyond your subscription cost).

The key limitation: Grammarly won't help you if you're starting from a blank page. It's a refinement tool, not a generation tool.

When to Use CraftMyLetter

CraftMyLetter is the better choice if you:

Don't have a draft yet. You need something written from scratch, fast.
Aren't sure how to structure a cover letter. CraftMyLetter handles the format, tone, and structure for you.
Need a letter in the next hour. CraftMyLetter generates in 30 seconds; writing one yourself takes much longer.
Want industry and role-specific customization. CraftMyLetter tailors the content to your actual job and background.
Prefer not to spend money on a subscription. One-time payments feel better than monthly recurring charges when you're job hunting.
Need multiple letters fast. If you're applying to 10 jobs, you need 10 different cover letters. CraftMyLetter makes that feasible in under 10 minutes.

CraftMyLetter is also better for non-native English speakers. Rather than struggling to write something and then polish it with Grammarly, you get a professionally written letter that you can customize. It's faster and less stressful.

Can You Use Both?

Yes—and it's actually a smart strategy.

Generate your cover letter with CraftMyLetter, then run it through Grammarly AI to polish it. Here's how:

Generate with CraftMyLetter: Answer the questions, get your letter in 30 seconds.
Copy to Grammarly: Paste the letter into Grammarly's editor or browser extension.
Polish with Grammarly: Let Grammarly check for grammar, tone issues, and clarity.
Make final adjustments: Implement Grammarly's suggestions and send.

This approach gives you the best of both worlds: a contextually tailored, well-structured letter (from CraftMyLetter) plus professional polish and refinement (from Grammarly AI). The whole process takes under 5 minutes.

Many of our users do exactly this. CraftMyLetter handles the heavy lifting; Grammarly handles the finishing touches.

FAQ: CraftMyLetter vs Grammarly AI for Cover Letters

Is Grammarly AI Good for Cover Letters?

Yes, Grammarly AI is good for polishing cover letters. If you've written a draft, Grammarly will catch grammar mistakes, suggest tone improvements, and help you sound more professional.

However, Grammarly is not good for writing cover letters from scratch. If you have a blank page, Grammarly won't generate content for you. You have to do the creative and strategic work yourself, then Grammarly refines it.

What's the Best AI Tool for Writing Cover Letters?

The best ai cover letter writer depends on your situation.

If you need speed and don't want to write from scratch, CraftMyLetter is the best choice. It's purpose-built for cover letters and generates them from context.

If you enjoy writing and want help polishing, Grammarly AI is great for refining what you've written.

If you want both—fast generation plus professional polish—use CraftMyLetter first, then Grammarly.

Other AI tools like ChatGPT and Claude can also write cover letters, but they require more prompting and produce less specialized results than CraftMyLetter. They're general-purpose tools, not cover-letter specialists.

Is CraftMyLetter Free?

CraftMyLetter has a free tier: 2 letters per month. That's enough to try it out and see if you like it.

If you need more letters, pricing starts at $4.99 for 10 letters (one-time, no subscription). That works out to about 50 cents per letter—much cheaper than a month of Grammarly Premium ($12).

Can Grammarly Write a Cover Letter From Scratch?

No. Grammarly is a writing assistant, not a writing generator. It helps you improve text you've already written, but it won't generate a full cover letter from nothing.

Grammarly's AI can suggest rewrites and improvements, but you have to provide the initial content. If you're staring at a blank page, Grammarly won't help you fill it.

The Bottom Line

CraftMyLetter and Grammarly AI serve different purposes. CraftMyLetter is a specialist: it generates cover letters fast from scratch. Grammarly AI is a generalist: it polishes all kinds of writing.

Choose CraftMyLetter if you need a letter written quickly and you're not sure where to start. Choose Grammarly if you've already written a draft and want professional polish. Better yet, use both: generate with CraftMyLetter, refine with Grammarly.
