What Is a Custom GPT?
A custom GPT is a specialized version of the ChatGPT model that's designed to perform a specific task. Instead of answering questions across every possible topic, a custom GPT follows tailored instructions that keep responses focused on a defined goal—like writing your resume.
Think of a custom GPT as ChatGPT with guardrails that keep the conversation on track.
How a Custom GPT Helps With Resume Writing
A custom GPT for resume writing uses the resources of ChatGPT but is built specifically to provide you with resume tips and actionable advice. It evaluates your resume content, provides feedback on its strengths and weaknesses, and offers practical suggestions based on both hiring and ATS best practices.
Unlike general AI tools, a custom GPT is designed to provide targeted guidance for resumes, job applications, and ATS optimization. For example, a custom GPT can:
- Contextually tailor your resume: A custom GPT can read job descriptions and suggest relevant keywords and skills to help align your resume with employer and ATS expectations.
- Help you overcome writer's block: Generate professional summaries, bullet points, or outlines from scratch to get your resume started—even when you aren't sure where to start.
- Adjust tone instantly: A custom GPT can shift language from academic to corporate, formal to conversational, or technical to simplified, depending on your target role.
- Provide structured feedback: It can evaluate clarity, formatting, and impact, and suggest improvements based on common hiring best practices.
- Answer specific questions: Wondering how long a resume should be for your industry? Not sure if professionals in your field are expected to share a portfolio? A custom GPT gives concise answers to your resume questions.

Just because a custom GPT is less prone to mistakes and hallucinations doesn't mean it's 100% reliable. It's critical that you review the accuracy of everything it generates before accepting AI input on your resume.
How to Use Our Custom GPT
Resume Now's Custom GPT for resume writing includes four built-in prompts to guide users through common resume tasks. You can also enter your own custom prompt at any time.
Take this resume as an example:
Review My Resume
This prompt provides an overall assessment of your resume, highlighting strengths, weaknesses, and opportunities for improvement. Use this prompt if you have an existing resume you want to refine but aren't sure how to get started.
Watch what happens when we use the resume example above with this prompt:

Rate My ATS Score
This option evaluates how well your resume may perform in applicant tracking systems, focusing on keywords, formatting, and readability. You can offer details about the job you're applying for to receive specific feedback on how well your resume aligns with the role. This prompt is ideal if you have a resume that you're looking to customize for a specific company or position.
Here's what happens when we try it with the example resume above:

Once you've improved your ATS compatibility with your custom GPT assistant, try out Resume Now's free ATS Resume Checker for a second opinion on your resume's ATS performance.
Improve My Resume
Input your resume to receive specific tips for areas you can improve. This prompt is great for zooming in and perfecting the finer details of your resume. Replace your job duties with action words, fix typos, and add measurable data to take your resume from being considered a "maybe" to an "absolutely."
Now let's try it with our example resume:

Start My Resume
Sometimes getting started is the hardest part. Use this prompt to find your footing and make a resume from scratch. Resume Now's Custom GPT will organize your ideas and provide a resume structure to get you started. Additionally, the custom GPT can answer any questions that may come up while writing a brand-new resume.
Let's give the custom GPT the information from our resume example and see what it comes up with:
My name is Nathan Yates, and I'm a Los Angeles–based technical writer with seven years of experience in content creation and technical documentation. I specialize in producing clear, user-focused materials that improve accuracy, efficiency, and engagement, including creating 50+ technical documents per month, increasing document accuracy by 20%, reducing workflow time by 15%, and boosting online engagement by 30% across previous roles at Innovate Tech Solutions, Visionary Media Group, and Tech Insight Corp. I hold a Master of Arts in Technical Communication from the University of California, Berkeley and a Bachelor of Arts in English Literature from Stanford University, and my expertise includes technical writing, SEO optimization, UI writing, document management, and project management, with beginner proficiency in Spanish, French, and German.

Try a Custom Prompt
Resume Now's Custom GPT isn't limited by these four built-in prompts. You can always ask for specific help or skip the general questions and dig straight into a resume detail that you're struggling with. Check out these sample prompts to help you refine your resume:
"Here's my current resume. Please point out three strengths and three gaps and suggest improvements."
A prompt like this one will give you a clear answer to what's working and what isn't, so you can focus on making improvements without losing sight of what you're already doing well. Limiting your prompt to three strengths and three gaps helps you prioritize the most important areas to focus on.
"Which resume format is best for someone with freelance experience?"
Use a prompt like this to answer nuanced questions about the specifics of your career journey. Whether it's freelance experience, employment gaps, or an unconventional career progression, the beauty of a custom GPT is asking these kinds of questions and receiving relevant answers that are tailored to your needs.
"What keywords should I include to pass ATS scanning for a project manager role?"
ChatGPT is built to predict the best response to a prompt based on vast amounts of data. Use those prediction skills to your advantage by asking our Custom GPT to play the role of the ATS and predict the keywords your resume needs.
"Rewrite my resume summary in a way that sounds confident but approachable."
Use a prompt like this one to strike the perfect tone with your resume. Find the perfect synonym or turn your casual stream of consciousness into a professional paragraph with the power of AI.
Build Your Resume With Resume Now's Custom GPT & Resume Builder
After refining your resume content with the custom GPT, you can easily move into the Resume Now AI Resume Builder to format your resume and download an application-ready document.
While our Custom GPT helps you perfect wording, structure, and ATS keywords, it can only provide plain-text content. Resume Now's AI Resume Builder lets you take that content and apply it to an ATS-friendly resume template, giving your resume a polished and professional look that's readable by ATS software and appealing to human reviewers.
Plus, the AI Resume Builder will suggest more options for enhancing and improving your resume.
Why Templates Matter for ATS
Applicant tracking systems scan resumes for specific information such as headings, skills, job titles, and keywords. Poor formatting—like unusual fonts, tables, or excessive graphics—can prevent ATS software from reading your resume accurately, even if your content is strong.
ATS-friendly templates help:
- Ensure proper parsing: Clear section headings and bullet points allow ATS software to correctly identify your experience and skills. Resume Now's library of resume templates includes ATS-friendly fonts and layouts that are parsed correctly every time.
- Support readability for humans: Even after passing ATS checks, hiring managers need a resume that's easy to scan and visually consistent. Templates provide visual hierarchy, spacing, and formatting that make your experience easy to digest.
How to Use GPT Content With a Premium Resume Now Template
After refining your resume with the Custom GPT, follow this simple workflow:
- Click the link in the Custom GPT to enter the builder.
- Select an ATS-optimized template in the Resume Now AI Resume Builder.
- Insert your GPT-refined content. Copy and paste or import your text.
- Adjust the formatting as needed to reorder your content and highlight your strengths.

An ATS-friendly resume template is designed to ensure applicant tracking systems can read your resume's content, including headings, job titles, skills, and keywords. Using a template designed to be accurately read by an ATS reduces the risk that your resume will be automatically rejected.
