CV tools measure, write, or organize, and that decides which one you need
I built one of the tools on this page, so weigh what I say accordingly. What surprised me when I lined them up is how little they actually compete. One hands you a score and leaves the writing to you, one writes finished text but optimizes toward the ad and can write in things your history does not contain, and one keeps dozens of applications tidy without making any single one of them stronger. They solve different problems, which is easy to miss when all three call themselves CV tools. So the question is not which tool is best, it is what you want in your hand when you are done.
A tool that gives you a score has left the work with you
JobScan and Resume Worded are both good at what they do, and what they do is diagnosis. They tell you that SAP is missing, that a bullet is flat, that your formatting is costing you. Then you open the document and rewrite it yourself, for every ad. At one application that is a fair trade, at twenty the rewriting is the entire job. There is a quieter cost as well: when a tool lists the words you are missing and leaves the writing to you, closing the gap by stretching is tempting, and a meeting you sat in on becomes a system you implemented. The number goes up, and it comes apart when the recruiter asks the follow-up question.
A tool that writes for you takes the content from the ad
ChatGPT and Rezi solve the first problem: they hand you finished text. But a model asked to tailor a CV to an ad optimizes for the ad, not for your career. In my own tests ChatGPT wrote an ERP migration into my CV that I have never run, at a company where I worked in an entirely different system. It read as credible, it would likely have cleared an ATS, and it would have fallen apart in the interview. That is why careerify does not write new experience for you: generation works from facts you approved yourself, and what changes is what the CV leads with, never the dates, titles or numbers.
Keeping the search tidy and making one application land are different problems
Teal sits on a different axis from the rest, and that is not a weakness. Their tracker is better than careerify's, and if your problem is losing track of which dozens of jobs you applied to, Teal is the tool to have. But a well kept pipeline does not make any single application stronger, and a stronger application does not tidy your pipeline. That is why the two can run side by side without paying twice for the same thing, which I say plainly in the comparison. careerify keeps a status, notes and a timeline per job, but that is not where its weight sits.
How to settle it yourself in twenty minutes
I have not run a paid side-by-side benchmark against any of these tools, and I am not going to invent numbers to win a comparison. Run the test yourself instead. Take an ad you actually want to apply to, put it through the tool you are considering and through careerify's free tier, which is one tailored application a month with no card. Then ask three questions: did the tool read the ad in the language it was written in, did you get out something you could send or only a list of things to do, and is there a single line in the result you could not answer for in an interview. The third question is the one that decides it, and it is the only one no tool can answer on your behalf.
Common questions
Which CV tool is the best one?
It depends on what you are missing, because these tools solve different problems. If you need to know what is wrong with your CV, a scoring tool like JobScan or Resume Worded is the right pick. If you need to keep many parallel applications in order, Teal is strongest at that. If you need a finished, honest version of your real CV for each ad, that is the job careerify is built for.
Is ChatGPT enough to tailor a CV?
For sharpening a line you have already written, it usually is. The problem starts when you ask for a CV tailored to an ad, because the model then pulls content from the ad and can write in experience you do not have. In my own tests it wrote in a systems migration I never ran, phrased so it sounded entirely credible. Read every line it produces and cut anything you could not back up in an interview.
What does careerify do that an ATS scanner does not?
An ATS scanner measures your CV and leaves the rewriting to you. careerify rewrites your real CV against the ad from facts you approved yourself, and it only changes what the CV leads with, never the dates, titles or numbers. You also get the keyword coverage against the ad and which terms are missing. What careerify does not do is search for jobs, apply on your behalf, read your inbox, or rewrite your LinkedIn profile automatically.
Can I use two of these tools at once?
Yes, and with a tracker like Teal it is even sensible, because organizing a search and tailoring an application are different jobs. Running two scoring tools in parallel, on the other hand, is paying twice for the same diagnosis. Try the new one on its free tier alongside the one you already pay for, on a real ad, before you switch.
Do these tools work outside English?
Most of them are built and marketed for the English-language market, so an ad written in another language gets matched against an English frame of reference and the local requirement terms are yours to handle. careerify works in ten languages, including Swedish, Norwegian and Danish. The simplest test is to paste in an ad in your own language and see whether the tool catches the actual hard requirements or only the English terms.
