How to tailor your CV with AI (and where ChatGPT falls short)

AI can save you a lot of time when you tailor a CV. It can read a long job advert in seconds, pull out what the employer is really asking for, and help you reword a bullet so it lands. But a general chatbot has one big limit: it can only work with what you give it. If the best evidence for this job isn't already on your CV, the AI can't find it. It can only polish what is there, or, worse, fill the gap with something that isn't true.

This guide shows you how to get the useful part without the risky part.

What AI is genuinely good at

• Reading the advert. Ask it to list the essential and desirable requirements, and which ones are repeated. That's a quick way to see what matters most.
• Matching. It can lay your CV next to that list and show which requirements you've clearly evidenced and which you haven't.
• Rewording. It's good at turning a vague line into a clear one, and at using the employer's words where they really describe what you did.
• Tidying. Consistent tense, shorter bullets, fewer repeated words.

Where general chatbots go wrong

1. Borrowing from the advert

Give a chatbot a job advert and your CV, ask it to "tailor my CV", and it may quietly add skills, tools or responsibilities that appear in the advert but not in your experience. It reads as a better match. It isn't true, and it tends to come out at interview.

2. Generic polish

"Results-driven professional with a proven track record" sounds tailored and says nothing. Recruiters read a lot of these lines. Specific detail beats confident adjectives.

3. Losing your numbers

When a chatbot shortens your CV, it can drop the figures and specifics that made a line convincing: the team size, the budget, the number of customers, the deadline you hit. Check that every number in your original still appears somewhere, or that you dropped it on purpose.

4. Not knowing what you left out

This is the biggest gap. Most people leave relevant experience off their CV because it didn't seem important at the time: the project they ran informally, the complaints they handled, the new starter they trained. A chatbot that only rewrites your CV will never ask about it.

A safer way to prompt ChatGPT, Claude or Gemini

Paste your CV and the job advert, then use something like this:

I'm applying for the job below. Using only the information in my CV, do the following. 1. List the essential requirements in the advert. 2. For each one, quote the evidence from my CV, or say "not evidenced". 3. For each requirement that is not evidenced, ask me one specific question that might uncover real experience I haven't written down. Do not rewrite anything yet, and do not add any skill, tool, number or responsibility that isn't in my CV or my answers.

Answer its questions honestly. Then ask it to suggest new wording only from your CV and your answers, and to keep every number you gave it.

Before you paste anything, remove your phone number, home address and anything else you wouldn't want stored, and check the tool's privacy settings.

Check every line before you use it

Ask three questions of each line the AI writes:

1. Did I really do this? If not, delete it.
2. Could I talk about it for two minutes? If not, make it smaller and truer.
3. Did a number or detail disappear? If so, put it back.

A worked example

Where Evident fits

You can do all of the above yourself with a careful prompt, and it works. Evident is built around the same idea so you don't have to set it up each time: it compares your CV with the job, asks up to five targeted questions about the gaps, drafts wording only from your answers, and you approve every line before your tailored CV is built. It never adds experience you haven't given it.

FAQs

What's the best AI tool to tailor a CV, and is there a free one?

Free chatbots such as ChatGPT, Claude and Gemini can do a good job if you use the prompt above and check every line yourself. The real difference with a dedicated CV tailoring tool is whether it asks you questions before it writes. With Evident, the first stage, where it compares your CV with the job and asks its questions, is free. You only pay if you want the finished tailored CV built.

Is it OK to use AI to write my CV?

Generally, yes, as long as everything on it is true and you can stand behind it at interview. Some employers publish guidance on using AI in applications, so follow it where they do.

Will a recruiter know I used AI?

They may notice generic, polished wording more than the tool itself. Specific, accurate detail reads as yours, whichever tool helped you phrase it.

Should I tailor my CV for every job?

For jobs you really want, yes. You don't need a new CV each time, but the profile, the order of your bullets and the words you use should reflect what that employer asked for. See our guide on tailoring your CV to a job description.

Is ChatGPT enough on its own?

For rewording, often yes. For finding the experience you left out, only if you prompt it to ask you questions first, as above.
