In 2024, Zety conducted a survey of 753 recruiters and found that 89% of hiring managers expect to see a cover letter, even if it was optional.
Whereas, 81% said they sometimes reject a candidate solely based on their cover letter.
This and several other surveys and research only prove one thing we’ve always known: Cover letters are indispensable. But that doesn’t change the fact that they are a headache to write.
Just so you know, Undetectable AI has a brilliant and free AI Cover Letter Generator tool that will gladly take this pain away.
Stick with me and I’ll tell you exactly how this tool works and how you can use it to land your dream job.
Key Takeaways
- Most recruiters still expect a cover letter, and many of them reject candidates if the cover letter is not up to the mark. A well-written cover letter is still important for landing interviews.
- An AI Cover Letter Generator is used to convert details and the job description provided by you into a polished draft that feels personal and natural, not robotic.
- Undetectable’s AI CV generator comes with HR-approved templates, LinkedIn integration, and easy options to adjust tone and style so every letter matches your personality and the role.
- If you want the best results, you should provide specific job details, personalise the greeting, proofread the draft, and make sure the final letter is concise and error-free.
What Is the AI Cover Letter Generator?
The AI Cover Letter Generator knows what recruiters want and how to play with words to give them exactly that.
If you do the effort manually, chances are you’ll spend hours sitting in front of a blank screen. But with this tool, you can have a strong draft in just a few clicks.
Of course, it’s not all as simple as it appears.
Never Worry About AI Detecting Your Texts Again. Undetectable AI Can Help You:
- Make your AI assisted writing appear human-like.
- Bypass all major AI detection tools with just one click.
- Use AI safely and confidently in school and work.
It feeds off the information you give it and turns it into a professional cover letter.
Behind the scenes, the tool has complex, trained language models that are designed to understand job descriptions, skills, and common recruiter expectations.
It then matches what you bring to the table with what the role is asking for.
And no, the cover letters don’t sound copied or robotic (if you use Undetectable AI CV generator) because this tool doesn’t pull from generic templates.
It builds sentences around your details.
The AI looks at your input, finds the most relevant points, and writes them in a natural way.
Having experimented with the Undetectable AI Cover Letter Generator tool a couple of times myself, it’s my go-to answer when someone asks what is the best cover letter generator in 2025?
This brings us to three questions probably swarming in your mind right now.
Who Should Use It
The AI cover letter generator is made for anyone who finds cover letters complicated, boring, or just too time-consuming.
- Students and fresh graduates who are applying for their very first jobs.
- Busy professionals who do not have the time to work on their cover letter.
- Career changers who need help framing transferable skills in the right way.
- Non-native speakers who want their English to sound polished and natural.
How It Differs From Generic Letter Templates
Most templates give you the same copy-and-paste phrases that make every letter sound the same. Recruiters spot them instantly.
Our AI Cover Letter Generator does not work like that.
It reviews your input details, understands the job description, and writes a letter that aligns with both.
This gives you a personal and specific cover letter every time.
Key Features of Our AI Cover Letter Generator
- Quickly turns your details and job posting into a professional draft.
- Option to pull your information directly from LinkedIn.
- Lets you tweak the tone, style, and layout so it reflects your personality perfectly.
- Creates unique letters that don’t sound robotic or copied.
- Gives you a ready-to-send file you can download in seconds.
I’d say this information sufficiently answers what is the best AI cover letter generator.
However, there’s still more I want you to know about this tool, which you can find out in the graphic below.
What Is the Best Cover Letter Generator in 2025?
I believe you already know where I stand on this one. But it would be a bit unfair if I didn’t give you a little tour of what else is out there.
Kickresume
Kickresume is a great option if you don’t mind signing up. You get to choose from professional and creative templates, but most of them are paid.
It has an AI cover letter writer powered by GPT-4, so it does a decent job at writing cover letters.
Sure, it has a robotic tone (as most AI-generated content does), but you can customize sentences in the end.
Canva
Canva is no longer just for social media graphics. Among other features, Canva also has an AI cover letter generator.
While it’s not perfect for all jobs, it sure is a great pick if you’re applying in the creative industry.
After your draft is generated, you can modify it with different fonts, colors, and layouts.
However, Canva is design-first. The AI writing isn’t as advanced as some other tools, so you might find yourself editing more heavily.
Grammarly
Everyone knows about Grammarly. But only a few people are aware of its AI-powered cover letter generator.
Students commonly ask what is the best cover letter generator for students that is free? Well, if you have a premium subscription to Grammarly, you can access this feature free of cost.
However, it’s not as good as it’s marketed. For starters, there’s a lot of manual effort involved. It doesn’t extract details on its own, so you’ll have to copy and paste the job requirements.
Then, the cover letter comes as plain text. This means you have to format it manually, which is another time-consuming task.
This brings me back to my original point. None of these tools compares to Undetectable AI’s Cover Letter Generator.
While I have many reasons to believe so, my primary factor is humanization.
Unlike other tools, you won’t have to spend hours humanizing your draft with this cover letter generator. It already produces natural and human content with no ‘AI-like’ feel.
Besides, it also offers many customization options, like the other tools. So why bother with the trade-offs when this Cover Letter Generator offers it all, and that too for absolutely free?
How to Write a Cover Letter with Our Generator
There’s absolutely no learning curve for how to write a cover letter generator. It’s a simple, three-step process.
Once you click the green button, you will be redirected to a screen. Enter your personal details here.
Then, hit next and fill out the job details.
Click next again and wait for the tool to generate the cover letter. Feel free to adjust the layout if needed. Otherwise, click download and select a format (TXT, PDF, DOCX).
Benefits of Using AI Cover Letter Generator
While you can keep the format the same, you can’t have the same details for every job you apply to if you really want to stand out. Customization is very important.
But customizing your cover letter for each and every job is quite tedious.
That’s why I always recommend using an AI cover letter generator, especially if you are applying to jobs frequently.
Undetectable AI’s Cover Letter Generator is a perfect, free alternative, so why go through the trouble of creating one on your own?
- Saves Time: Writing a cover letter takes a lot of time, and it’s also frustrating. Imagine the time you could save by letting an AI CV generator take care of your cover letter!
- HR-Approved Templates: What good is a fancy cover letter if it goes against the hiring standards? Undetectable AI only uses templates that HRs have already approved. You’ll get a cover letter that looks good and reads well.
- Sounds Human: This one is pretty important. With Undetectable AI’s built-in humanization tool, you can always make sure your cover letter feels human-generated. No other tool offers such convenience.
- Customized Drafts: The cover letters do not all read the same. You can even test this for yourself. This Cover Letter Generator takes its sweet time to make sure every cover letter is customized as per the job description and requirements.
Best Practices for Using AI Cover Letter Generator
What is the best AI cover letter generator? Undetectable AI’s Cover Letter Generator. Yup, we’ve established that much until now.
But if you truly want the best results, here is what you gotta do.
Feed a Strong Input
As with all the AI models, the better your input, the better the results. This goes without saying. Don’t copy-paste a vague job description. Be specific.
Pull the most important requirements and skills from the posting.
Add a few achievements from your own experience that show you’ve done something similar.
Personalize the Draft
Cover letters mostly begin with ‘Dear Hiring Manager’. While there’s nothing wrong with it, a little personalization can increase your odds of getting an interview call.
See if you can find the hiring manager’s name. Look it up on LinkedIn or the company’s official website. It’s a small effort that can make your letter warmer and less canned.
Adjust the Tone
A cover letter should neither be too formal nor too casual.
If it doesn’t strike that balance, ask the AI to rewrite it in your preferred tone.
This will save you hours of manual editing.
You can also use the AI Rewording Tool to fine-tune your cover letter’s tone and clarity.
It helps rephrase AI-generated text so it sounds more like you: confident, polished, and tailored to the role without losing the message.
Double-Check for Errors
Even AI can sometimes make mistakes. A missing company name, wrong job titles, and repeating the same skills are small errors that can go unnoticed if you don’t proofread the draft.
Believe me, nothing turns off a recruiter (an ATS system) faster than a sloppy error. Always make sure your cover letter has all the accurate details.
Keep It Short
AI can sometimes go on and on, especially if you provide it with abundant details. But a cover letter isn’t storytime.
Trim it if it’s longer than one page. Try to wrap it up in 4 paragraphs, i.e., intro, two body paragraphs, and a short closing.

You can’t skip cover letters because recruiters still expect them, and the truth is, a strong one can open doors.
