How to Use ChatGPT to Write a CV and Cover Letter in Nigeria Without Getting Caught (AI Tell Guide)

Where you are right now

Recruiters spot an AI-written CV in the seconds it takes them to swipe. The same free ChatGPT that writes your CV writes hundreds of other CVs the same week, and the tell words are all over every one of them.

You have felt this fear even before you acted on it. The doubt steps in the minute a perfect CV appears on a screen and reads like it could belong to anyone. Send raw output like that and the recruiter flags it. Rewrite it yourself and risk making it worse than the bot.

This guide is the third option: the workflow that does not get you caught, because nothing you submit is raw ChatGPT output. You start from ONE real job ad. You feed in ONE real history that only you have. And you do the final edit yourself, on your phone, word by word.

By the end you will have a CV and a cover letter built for one specific job, with the AI tells removed, saved as a PDF in your real name, ready to send tonight.

Words you will see in this guide

Four words come up again and again here. Know them once, and every step reads clean.

• A prompt is the instruction you type into ChatGPT, the sentence that tells it who you are and what to write.
• A bullet point is one line inside a CV entry, and a good CV builds each job from three to five of them.
• An ATS is a robot that scans your CV before any human sees it, looking for dates, job titles, and the words in the ad.
• An AI tell is anything that makes a recruiter think a bot wrote your CV, a word like 'leveraged', a missing date, or a sentence no person would say.

What you need before you start

You already own everything on this list.

• A phone with free ChatGPT. Sign in, stay on the free plan, and ignore the upgrade banners. A payment screen should never appear while you do this guide. If one does, close it and keep going.
• Your real history written out. Every job, school, and duty you have actually done, in your own words, in your notes app. Real facts only. ChatGPT can only rewrite what you give it, so what you write here decides your whole CV.
• One real job ad copied in full. The whole text of the one job you actually want, pasted into your notes app. You need one ad only, because the whole method is one CV per ad.

Remember THE ONE-AD RULE: you never build a CV without its ad. The ad gives you the words to use, the duties to lead with, and the exact job title to match.

Step 1 - Open the job ad and free ChatGPT on your phone

The ad comes first, always. The ad is the boss of this workflow, and the chatbot is just the typist.

Open your notes app where the ad text lives, then open ChatGPT beside it. On many phones you can split the screen so both stay visible. If yours cannot, switch between the two apps with the back button. That is enough.

Check the top of the ChatGPT screen before you type. It should be on the free model, and it should not be asking you for money. The free plan writes a full CV and a cover letter with room to spare, and it never shows a payment screen while you are doing this guide.

Step 2 - Feed ChatGPT your real history before anything else

Type nothing else first. No ad, no question, no 'help me write a CV'. Just your real history, in your own words, in one message.

Paste this template and change only the bracketed parts:

My real history, in my own words:

Name: [Your full name]
Phone number: [Your number]
Email: [Your email]

Education:
- [School name], [year started] to [year finished], [course or certificate]

Work history:
- [Job title] at [business name], [year started] to [year finished]

Duties I handled there:
- [One real duty, a short line]
- [One real duty, a short line]

Other real things I have done:
- [A project, NYSC, volunteering, work for family or church]

Use only this history from now on. Do not invent anything.

CLEAR RULE: ChatGPT can only rewrite what you give it. Thin history gives a thin CV, and that is CORRECT. A two-line CV from your real life beats a full page of invented jobs, because a recruiter can verify one job title with one phone call. Never invent a job, a school, or a duty. One invented line in the CV ends the process the moment it gets checked.

Step 3 - Paste one job ad and ask for one tailored draft

Now paste the full ad into the same chat, right below your history, then send this:

Here is the full job ad for the job I want:

[paste the entire ad text here]

Write one CV for this one job. Use only the history I gave you. Match the words and duties in the ad. Keep my real dates and my real job titles. Do not invent anything new.

Then tell me which duties from the ad my history is missing.

The draft you get back should read like your history wearing the ad's vocabulary, not like a stranger's career. Check that it used your real jobs and your real dates before you read another word.

CLEAR RULE: one CV per ad. A generic CV sounds like a bot, because it is the one draft ChatGPT hands to everyone who asks. Keep a generic CV and you are not doing this guide, you are handing a recruiter the same file a hundred other applicants are handing them. Each ad gets its own CV, built from the same real history.

Step 4 - Check the AI tells before you touch anything

Before you edit a single word, run the whole draft through this checklist. Skip it and what you submit is Step 3's raw output, which is the exact thing this guide exists to stop.

• Look for words no one says out loud. 'Leveraged', 'dynamic', 'proven track record', 'result-oriented'. If you would never say it on a bus, it is a tell.
• Look for missing or wrong dates. Every job and school entry needs a start year and an end year. ChatGPT blurs the dates because it never knew them, and a missing date reads like a gap you are hiding.
• Look for claims your history does not support. If the ad asks for 'social media management' and your history never mentions it, a draft that suddenly contains it is a lie wearing a tell.
• Look for sentences too polite and lifeless to be yours. ChatGPT writes long, round sentences. Real CVs carry short, plain ones.

A fresh ChatGPT draft will show you several of these. That is not a failure. It is exactly why Step 5 exists.

Step 5 - Humanize the draft. This step is the entire game.

The tells from Step 4 do not leave by themselves. Here is where you remove them with your own hands, and nothing else in this guide matters more.

• Rewrite every bullet in your own words. Say the duty the way you would tell your mother you did it, and type that.
• Cut every bullet to one line. If it wraps twice on your phone screen, it is too long.
• Swap every tell for the plain word. 'Leveraged' becomes 'used'. 'Result-oriented' becomes an actual sentence about your actual work, or it disappears.
• Restore every real date. If you worked the shop from 2019 to 2022, the CV says 2019 to 2022, because missing dates are tells.

When the bullets read like you, read the whole CV aloud on the bus on your way to work. The places where you stumble are the places that still sound like a bot. Reword those sentences until they come out of your mouth easily. Your tongue is the best AI detector you have.

Optional, if you want a second check: paste your edited CV into a fresh chat and send this. It points out problems, and you still do the fixing:

Here is a CV I edited myself. List every word, phrase, or sentence that sounds like ChatGPT wrote it, and any dates that are missing. Do not rewrite anything. Just tell me what to fix.

Take the points it raises, run them through your own checklist, and fix them yourself. Never paste its new draft over your edits, because the whole point of this guide is that the last hand on the file is yours.

Step 6 - Cover letter, one job, your own 'why' sentence

AI cover letters fail twice: they are about no one, and they fit every job at once. Yours will be about you, for one job.

Before any prompt, write ONE sentence in your notes app: the real reason you want this job. Not the polite reason. The real one. You have used this company's product for years. This department does exactly what you did at your last job. This role is the same work you already do on Sundays for your family's shop. Write that sentence in your own words, because ChatGPT cannot write it for you. It does not know why you want the job.

Then paste the ad and your sentence into the chat and send:

Here is the job ad again:

[paste the full ad text here]

Here is my real reason for wanting this job, in my own words:

[your why sentence]

Write one cover letter of three short paragraphs in plain English. Paragraph one: the job and my reason, using my sentence almost word for word. Paragraph two: two duties from my history that match this ad. Paragraph three: one line saying I am ready to start. Do not add skills I never listed.

The heart of the letter is your own sentence, so the whole letter reads like you wrote it. Read it aloud once, and reword the one place where you stumble.

Step 7 - Save, name, and send

• Export a PDF from your phone, free. Copy the full CV text into your notes app, then use Share and pick 'Save as PDF' or 'Print and save as PDF'. Most phones do this with no extra app and no payment, and no paid tool is needed anywhere in this guide.
• Name the file with your real name. 'Chinedu Okafor - Sales Officer CV.pdf'. A file called 'cv final final v3.pdf' is a small tell of its own.
• Do the final pass. Check every date once more, and spell-check the ad's own words most carefully, the company name and the job title. A letter that misspells the company you are applying to is dead before it is read.
• Send the file itself. Attach the PDF to the email in the ad, or send the PDF on WhatsApp. Never send a screenshot of the CV, and never send a link to your ChatGPT chat (recruiters click links from strangers far less than you hope).

Test it once before you send: send the PDF to your own WhatsApp and open it, to confirm it opens cleanly on a phone screen. This whole workflow is text-only and data-light, a few dozen messages and one small PDF, so a small bundle carries it easily. Run it once and your one CV is done, named, and sent.

Still scared ChatGPT will come out in your CV?

There is nothing left in that file that a bot wrote. The history is yours, written out in your own words before ChatGPT ever saw it. The ad is one real ad, not a template. And the final edit was your hands, on your phone, in your own sentences. What exactly would a recruiter catch?

You are not submitting raw ChatGPT output. You are submitting your own history, aimed at one real job, cleaned by your own tongue and your own hands. The tell was removed at the source, because it was never in the file to begin with.

Knowing the steps is not the same as sending the file. Run them once, and your name goes on a real PDF, not on the list of people who only ever explained the process.
