Is your tailored resume still true?
Ask an AI to tailor your resume to a job and it will often borrow the posting’s own words, or make a number of yours a little bigger. Paste both versions and the posting, and see every claim that was not in your original, before an interviewer asks about it. Nothing you paste leaves this browser.
Checking an email or an essay rather than a resume? Edit Check shows every detail a rewrite moved.
New to this? What it does, in plain words
It compares the resume you wrote with the one an AI tailored, and lists everything in the new one that your own resume does not back up.
Use it after ChatGPT, Claude, Gemini or a resume builder has rewritten your resume for a job. It finds the skill that came from the job posting and not from you, the figure that grew, the date that moved and the bullet point that is entirely new. You decide what is true and keep it. The rest goes back.
What you need
Your original resume, the tailored version and, if you have it, the job posting. No API key and no sign-up. A resume holds your name and your phone number, and here it stays on your device.
How to use it
- Paste your original resume, then the tailored version. Add the job posting so the page can see which words came from it.
- Read the list. Each item is something the tailored resume says that your original does not.
- Press True of me on anything you can back up in an interview.
- Copy the prompt at the bottom to have everything else taken out or put back.
Your resume
ExampleThe tailored version
The job posting
Your resume stays on this device. The check is done by rules in this page, with no AI and no upload.
Paste your resume and the tailored version to see what the AI added. With the job posting too, it also shows which words were carried over from the posting.
Claims to check
Everything the tailored version says that your own resume does not.
What the posting repeats
The words this posting uses more than once, and whether each version of your resume mentions them. This is not a score, and this page does not guess how any employer’s software ranks a resume. Add a missing word only where it is true of you.
Ask the AI to take out what is not true
Names each claim still on your list. Anything you marked True of me is left alone.
Tailor it honestly from the start
Use this when you ask an AI to tailor a resume. It reorders and rewords what is yours and lists the gaps for you to answer.
Tailor my resume to the job posting below. Use only what my resume says: reorder it, and reword its points in the posting's terms where my experience matches. Do not add any skill, tool, title, employer, date, number or qualification that is not in my resume, and do not change any figure or date. After the resume, list each requirement in the posting that my resume does not cover, so I can tell you whether I have it. My resume: """ [paste your resume] """ The job posting: """ [paste the posting] """
Where to next
Why a tailored resume needs a truth check
An AI asked to match a resume to a job will close the gap with the posting’s words unless it is told not to. Each borrowed word is a question you may be asked in the interview.
- In your browser. Paste the textsYour resume and the tailored version, with the posting if you have it.
- In your browser. New claims are foundWords carried over from the posting, and figures or dates that are new or different.Instant
- In your browser. Keep what is trueMark each claim you can back up. Everything else stays on the list.
- In the AI you use. Have the rest removedOne prompt that takes out or restores only those points.
What it looks for
- Words from the posting. A skill or a tool that appears in the posting and in the tailored resume, and nowhere in your original.
- Figures that changed. “About 20%” that became “25%”, a team of 6 that became 8.
- Dates that moved. A start year that slipped earlier, or a role that now ends later.
- New names. An employer, a product, a certificate or a tool your resume never mentions.
- New bullet points. Whole lines with no counterpart in your original.
- Lost caution. “Around 40 calls a day” that became “40 calls a day”.
“Rebuilt the weekly route plan using Excel and SQL.”
Not quite. SQL came from the posting, not from you. If you have never used it, this line fails at the first interview question about it.
“Rebuilt the weekly route plan in Excel, cutting late deliveries.”
Yes. It leads with the tool the posting asks for and adds nothing you did not do, as long as the result is one your resume already states.
“Advanced Excel and SQL expert with route planning experience.”
Not quite. Both “advanced” and “SQL” are the posting’s words. Neither is in your resume.
“Proficient in data tools including SQL.”
Not quite. Vague wording does not make an untrue claim true.
Tailoring changes the order and the wording of what you did. It does not change what you did.
What it cannot do
It cannot know what is true of you. A word it lists may describe something you really did and left off your resume, which is a reason to keep it and to add it to your original. It compares words, so a claim reworded beyond recognition can pass, and an ordinary word that happens to be in the posting can be listed. It does not score your resume, and it does not predict what any employer or any hiring software will do with it.
Questions
Is it OK to use ChatGPT to tailor my resume?
Rewording and reordering your real experience for a job is ordinary editing. The risk is content you did not supply: a skill or a number the AI added to match the posting. Check the tailored version against your original before you send it, and be ready to talk about every line. The guide to AI for job applications covers the rest.
Does my resume get uploaded?
No. All three texts are read in this browser and nothing you paste is sent to thinkhard.si or anyone else. They are kept in this browser so they survive a reload, and Clear all removes them. Only if you press Open in ChatGPT or Open in Claude does the correction prompt go to that app, because you sent it there.
Is this an ATS checker? Will it give me a score?
No. It shows which of the posting’s repeated words your resume mentions, which is useful, and it gives no score. Each employer sets up its own hiring software, and nobody outside can see how a given one treats a resume. We do not repeat figures about how many resumes software rejects, because we could not find a study behind them.
The AI added a skill I do have. What now?
Press True of me and it leaves the list. Then add it to your original resume in your own words, with where you used it, so the next tailored version rests on something real.
Can I check a cover letter the same way?
Yes. Paste your resume as the original and the cover letter as the tailored version. The list will be longer, because a letter says things a resume does not, and its figures and dates are still worth checking.
