How to write an ATS-friendly resume with AI: a step-by-step guide

A practical workflow

Rather than trusting a single tool, combining two tools gives more reliable results:

1. Draft generation: Build your first draft with Kickresume or Rezi.
2. ATS check: Test your resume against the target job listing with a separate ATS-scanning tool.
3. Final polish: Use ChatGPT or a similar general-purpose model to simplify sentences, remove redundancy, and better match the language of the job listing.

Mistakes to watch out for

• Sending the same resume to every job: Since AI tools are fast, producing a version tailored to each listing's keywords now costs nothing — skipping this is a real missed opportunity.
• Leaving AI-invented achievements uncorrected: Models sometimes add a "plausible" accomplishment you never actually had. Check every sentence against your real experience.
• Choosing an overly complex design: Visually striking templates are often the worst choice for ATS. A simple, single-column, standard-heading format is always safer.

The limits of AI resume tools

AI tools don't know your background — they only organize and adapt the information you give them. That's the biggest risk: the tool adding details that "sound good" but aren't true. Numerical claims in particular ("increased sales by 40%") can end up as the model's plausible-sounding guess rather than something you verified — and if you can't defend a claim like that in an interview, it seriously damages trust.

A second limitation: AI tools don't always use industry-specific jargon correctly. Text generated for a very specific engineering or legal role, for example, can end up full of generic phrasing rather than the field's real terminology. That's why the final text needs a review — ideally by someone in that field, or at minimum a close comparison against the actual job listing.

Using AI for cover letters

Most of the same tools also offer cover letter generation alongside resumes. What actually works here isn't just telling the AI "write a cover letter" — it's giving it the problem the company is solving, the 2-3 key requirements from the job listing, and a concrete experience of yours that matches those requirements. With those three inputs, the output stops feeling like a template and becomes genuinely tailored to that listing.

Updating your LinkedIn profile with AI

After updating your resume, updating your LinkedIn profile to match increases the odds recruiters actually find you. Feeding your finalized resume to ChatGPT or a similar model with a request like "write a LinkedIn 'About' section that matches this resume, first person, warm but professional tone" can produce a solid draft. The same rule applies here too: don't copy the output as-is — adjust it to sound like your own voice, or the profile risks reading as generic as everyone else's.

Using AI for portfolios and GitHub profiles

If a technical role also asks for a GitHub profile or portfolio site alongside your resume, AI tools help there too. Simplifying a project README so a non-technical recruiter can understand it, or rewriting portfolio project descriptions from "what I did" into "what problem I solved and what the result was," creates a narrative consistent with the rest of your resume — and a general-purpose model can help with both.

Using AI for interview prep

Beyond the resume and cover letter, AI tools are also useful for interview prep. Feeding a model publicly available information about the target company (website, recent news) and asking it to "generate 10 likely interview questions specific to this company" gives you a realistic practice run. The same caveat applies: the model can produce outdated or inaccurate information about the company, so verify critical details against the company's official sources.

Bottom line

AI speeds up the resume-writing process, but it doesn't take the thinking out of your hands entirely — you still need to verify accuracy, tailor it per listing, and test ATS compatibility. Used correctly, it lets you apply to far more jobs, far more precisely, in the same amount of time.
