Key takeaways
- An ATS checker is a tool that reads your CV the way an applicant tracking system would and shows you what it understood and what it missed.
- Of seven checkers tested on 11 November 2026 with the same CV, two asked for an account before showing anything, one failed twice and two kept half of the report locked.
- The same CV scored anywhere between 62 and 97 depending on the tool, so the number cannot be compared across checkers; the list of concrete problems is what matters.
- The worst mistake we saw was a false gap: one tool said Google Ads was missing from a CV that named it three times.
How we tested each ATS checker
To keep the comparison fair, we always used the same material: the CV of an invented person, Ana Ejemplo, a digital marketing specialist in Madrid, as a one-page, one-column PDF with no tables or graphics. The CV is written in Spanish, because we tested the tools that job seekers in Spain and Latin America actually find. It is deliberately clean: if a tool finds lots of reading problems in it, the problem lies with the tool.
When a checker asked for a job ad, we always pasted the same one: Performance Marketing Specialist, with Google Ads, Meta Ads, GA4, Google Tag Manager, SQL, advanced Excel and TikTok Ads among the requirements. Some of those are in the CV and some are not, so you can see whether the tool gets the gaps right.
- No accounts, no payment
We opened each page as anyone would, without signing up. If a tool required an account to show the result, we noted it and stopped there.
- The same PDF everywhere
We uploaded the same file to every checker and, where possible, the same job ad.
- What it showed for free
We recorded the score, the problems it flagged and which parts it kept locked.
- Checked against the real CV
We checked every flagged problem against the CV itself: if a tool said something was missing, we looked for it.
Results from the seven ATS checkers
The table sums up what we saw on 11 November 2026, in alphabetical order. These tools change often, so a tool that asks for an account today might not tomorrow, and vice versa.
| Tool | No account? | Language | What it gave |
|---|---|---|---|
| AI ResumeGuru | Yes | Spanish | 97 out of 100, with 3 points held back for the full review. One tip only: Excel and HubSpot listed without an example of use. |
| Cernoria | Yes | Spanish | 93 out of 100, broken down into 6 parts. It flagged that the job title was not on its own line under the name and that the CV was short on words. |
| Enhancv | Yes | Spanish | 80 out of 100. With the job ad, a 13% match and Google Ads flagged as missing, although it was in the CV. Several sections locked. |
| Jobscan | No | English | Asks you to sign up before showing the analysis. |
| Kickresume | No | English | Asks you to sign up after uploading the PDF. |
| LoopCV | Partly | Spanish | 62 out of 100 with 3 of 6 points visible; the rest needs registration. It said keywords were missing without having been given any job ad. |
| Novorésumé | Yes | English | Asks you to accept its terms and allows 2 uses a month. It returned an unexpected error twice. |
What each one does well and where it falls short
- AI ResumeGuru: quick and honest. It explains that no checker replicates a specific ATS and holds back the points it does not assess instead of giving them away. It does not compare with a job ad without an account.
- Cernoria: reads the PDF in seconds, uses no AI for the score and does not store the CV. It shows what is fine and what to fix, part by part. It does not compare with a job ad on this page either.
- Enhancv: the only one in the test that compared against the job ad without an account. But the match percentage rested on a false gap, and much of the report sits behind the paid plan.
- Jobscan and Kickresume: among the most cited in English, but they show nothing until you register. If you would rather not create an account, they are no use for a quick check.
- LoopCV: gives a score in seconds, but hides half of the points and warns about missing keywords without knowing which role you are aiming for.
- Novorésumé: the flow is clear and asks for country, experience and the job ad, but in our test it never produced a result.
The most common mistake: the false gap
Many checkers promise to tell you which words from the job ad are missing from your CV. That is useful, because some recruitment systems filter on those words. But it only helps if the tool gets it right. In our test, one tool flagged Google Ads as a missing skill when the CV mentioned it in the profile, in the experience and in the skills list.
A false gap is worse than no report at all: it pushes you to rewrite something that was fine or to repeat a word for no reason. Another tool talked about missing keywords without having read any job ad, which cannot be true for any particular role.
Before you change your CV because a checker says so, search for the word in your own text. If it is already there, the mistake is the tool's, not yours.
Which free ATS checker to use for what you need
- If you want to know whether your PDF reads properly: AI ResumeGuru or Cernoria, both without an account.
- If you want to see your CV next to a job ad: Enhancv did it without an account, but check by hand every word it flags as missing.
- If you are applying in English and do not mind signing up: Jobscan and Kickresume are the best known options.
- If you only want a number: any of them will give you one, but it means nothing across tools. The same CV scored 62, 80, 93 and 97.
What no ATS checker can tell you
An ATS checker reviews the form: that the text can be read, that your contact details are there, that the dates make sense and that your experience shows results. It does not know how the system at the company you are applying to is set up, nor how much weight the recruiter gives each requirement. None of the seven claims otherwise if you read them carefully.
What changes your chances most is not going from 90 to 97 points, but making your CV answer what each job ad asks for: the role in your headline, the requirements you meet backed by a concrete example and your achievements with numbers. For that, the most useful review is still reading the ad with your CV beside it.
And to do it with your own CV: What an ATS sees in your CV.
Frequently asked questions
What is the best free ATS checker?
There is no single best one. In our test on 11 November 2026, AI ResumeGuru and Cernoria gave a full analysis without an account, and Enhancv was the only one that compared against a job ad without signing up, although with a false gap.
Are there free ATS checkers that work without signing up?
Yes. Of the seven we tested, AI ResumeGuru, Cernoria and Enhancv showed a result without an account, and LoopCV showed half of one. Jobscan and Kickresume asked us to register before showing the analysis.
Why does each ATS checker give a different score?
Because each one measures different things on its own scale. The same CV scored 62, 80, 93 and 97 in four tools, so the number is only useful for comparing your CV with itself in the same tool.
Does an ATS checker guarantee my CV will get through?
No. A checker makes sure your CV can be read and covers the basics, but it does not know how each employer has set up its system. It helps you remove formatting mistakes, not secure an interview.
What should I do if the checker says a keyword is missing?
Search for it in your CV first. If it is there, the warning is the tool's mistake. If it is not and you genuinely have that skill, add it with a concrete example in your experience, not only in the skills list.
