AI job matching in the UK: what it does and does not do

How do AI job matchers rank you?

Every matcher does three things: it turns your CV into a list of terms, it turns each advert into a list of terms, and it compares the two. The differences are in how the lists are made and what the comparison is allowed to do.

Some products hand the whole job to a language model and ask it how well you fit. That gives a fluent answer and an unrepeatable one: ask twice and the number moves. Fitread does the opposite. One vocabulary of skills and their aliases reads both your CV and every advert, each advert is indexed once, and the comparison is arithmetic over that index. The same CV and the same advert always give the same score.

The index covers 30,552 live UK adverts (read 24 October 2026), so Job Match ranks every live advert Fitread holds, not a sample a model happened to look at.

What does a fit score mean?

A fit score, as Fitread uses the term, is how much of the advert your CV shows: up to 70 points for the advert's skills, weighted as the advert weights them, 15 for the job title and 15 for the sector. It is a share, not a probability, and the reading shows each part so you can disagree with it.

Bands rather than decimals: strong from 70, good from 50, partial from 30. A thin advert, or one essential skill missing, holds the score at 49 at most, and the reading says so. A score says nothing about whether you would want the job, and a score of 40 can be one missing word.

The working is public: how Fitread reads your CV lists every weight, hold and band, read from the code.

Where does AI help, and where must it stop?

AI is good at words and bad at being a referee. So Fitread lets it explain and never lets it decide. The score is fixed by code first. Then the AI writes the review and the opening lines of a letter around those figures, labelled "Written by AI", and every sentence is checked against your CV: a sentence that names a skill, number, date or employer your CV does not contain is removed.

That is the honesty line. A matcher that lets a model invent a skill to lift your score, or soften a gap to keep you reading, is not matching you to a job; it is matching you to a sale. Fitread's pitch is short: fast, and it never lies on your behalf.

There are things no matcher can know. Which system an agency uses: adverts rarely say. Whether you will be shortlisted: a person decides. Whether your CV is true: Fitread reads what it says and never checks it. What people are actually paid: advertised rates are not rates paid. Fitread says so on the reading rather than pretend.

What should you ask of any job matcher?

Ask to see the inputs. If a product shows you a percentage and nothing underneath it, you cannot tell a real gap from a parsing error. Ask whether the same CV and advert give the same answer twice. Ask where the jobs come from and when they were counted. Ask what the AI is allowed to change.

Fitread answers those on the page: every figure carries the date it was read, every score opens to its parts, and the AI's text is labelled and checked. Job Match is the ranked list; Read my CV is one advert, free, no account; Pro is the whole list and every finding.

What do live UK adverts look like right now?

Of the 30,552 live UK adverts Fitread read on 24 October 2026, 5% state a day rate or salary and 43% say whether the work is remote, hybrid or on site. Those are facts the adverts state, not estimates, and Fitread shows a missing one as missing.

The biggest role by live adverts is Social Worker, with 1,222. The skills its adverts name most: Social Work England registration (93%), Care planning (50%), Child protection (statutory) (40%), Local government (22%). The full table, twenty roles and their eight most-named skills, is in the skills UK adverts ask for.
