How do AI cover letter generators work?

Before we dive into your options, let’s start by understanding one of the biggest names in AI: ChatGPT — the most widely used AI generator for text content.

The “GPT” in ChatGPT stands for “generative pretrained transformer.” GPT models use a form of machine learning to recognize patterns and produce outputs that match those patterns. The more content it’s exposed to, the more effective it is at mimicking human-made content.

So, what does that mean for your cover letter?

It means that a ChatGPT cover letter can be complex and convincing enough to seem as though a human wrote it. In fact, GPT-3.5 is probably the best completely free AI cover letter generator out there. ChatGPT-4 is even better, but it requires a paid account.

What’s the catch?

Both versions of ChatGPT can produce the foundation for a strong cover letter — if you give them the right prompts. GPT isn’t a mind reader. It tends to take your input very literally and give somewhat simple answers. To make the most of ChatGPT, carefully composing and perfecting prompts is an essential skill. You have to be specific to get results.

For example:

Ineffective prompt: “Write me a cover letter for a kindergarten teaching job.”
Effective prompt: “Write a cover letter for a kindergarten teaching role that mentions my passion for early childhood development, experience handling large groups of 20 rowdy children and highlights a track record of student success throughout my 10-year career.”

Even after using a prompt like this one, you’ll have to edit the generated result to include your specific information. Depending on the AI cover letter generator you use, you must add your career details either before or after the letter is generated to ensure you hand in a personable and unique letter that conveys your unique qualifications.

That’s why, to make a great AI-generated cover letter, an AI tool that’s specifically designed to help you produce a strong letter is best.

For this reason, our list of AI cover letter generators includes only tools that were specifically designed to help you produce your best cover letter — without the effort of developing prompt engineering skills.

How to land an interview with an AI cover letter generator

Whether you’re using an AI cover letter tool or trying your hand at prompt engineering for ChatGPT, there are a few things you should keep in mind to ensure you get the best possible result.

Add your career details: AI isn’t magic. It doesn’t know your career better than you know yourself. Only when you input specific personal details will the AI generator produce strong and specific results. So take the time to gather and input as many details about your career as you can.
Edit the generated text: The content AI generates tends to be boilerplate, so don’t use it as-is. Trust us, “Why does your cover letter sound like a robot wrote it?” is not an interview question you want to have to answer. For a truly impressive AI-generated cover letter, edit any generic text to add specific details that’ll show your unique personality and accomplishments.
Tailor it to the role: Make sure that your cover letter isn’t just personal to you — it should feel personal to the role as well. To write a cover letter that stands out to both human eyes and the applicant tracking systems (ATS) that many employers use to screen applications, ensure that your resume and cover letter both include keywords from the job listing.
Study cover letters from successful candidates: If you’re not sure what your letter should look like, it can be hard to know if the AI cover letter generator you used has done a good job. Study cover letter examples in your field and consider what kinds of skills and experience the candidates choose to highlight. Your letter should be unique to you, but should also measure up to standards for your industry.

With these tips in mind, let’s look at the best options out there for building a cover letter that opens doors.

Writing help: Grammarly is best known for their plugin that helps correct the spelling, grammar and word choice of your documents. However, its robust cover letter builder uses AI to produce text as well.

Fully free trial: This AI cover letter generator is free for your first several attempts, allowing you to tweak your results until you’re happy with them.

Cons:

Short and generic content: Because this generator doesn’t prompt you to include very much information, the cover letters that it generates are fairly short and generic. It doesn’t produce much detail and would need significant fine-tuning to work well.
Costly payment: Because all three membership tiers are for lifetime access, once you’ve used up your free attempts, LazyApply requires a pretty significant payment.

Key Takeaways

Customize It’s not a good idea to rely on AI to generate a cover letter for you without being prepared to provide your own input. AI isn’t magic and should be supplemented with personal details.
Edit Remember that once your AI-assisted cover letter is complete, you can edit it extensively. The best AI cover letter is one that uses AI as a launchpad for ideas instead of accepting its output as the final product.
Style Some AI cover letter generators include a cover letter template, while others just provide text. If you’re sending your cover letter as an email, text is enough, but for a complete document, make sure to pick a cover letter template style that represents your personal brand.
Pick the right builder Choose an AI cover letter generator that fits your needs. From using builders that will format and style your cover letter for you to getting creative with GPT-generated text and styling it yourself, the possibilities are endless. Try out a few tools and see what feels best to you.
Target the role Make sure to include details from the specific role so that your cover letter doesn’t read like repetitive boilerplate. Include specific details from the job listing in your prompt for your AI-generated cover letter to target it to the job you’re after.
