What is Quarrion? An honest tour of the pipeline
What the agent actually does at each stage — discovery, scoring, research, tailoring, applying and follow-up — and the parts it deliberately leaves to you.
Quarrion is an AI agent that runs a job search. The one-line version: it scans, scores, tailors and applies — you interview. That line is doing a lot of compression, so this post walks through what actually happens at each stage, and, just as importantly, what the agent deliberately does not do.
Discovery: reading the boards so you don't
Openings are scattered across more than a hundred places — the big aggregators, the specialist boards, and the applicant tracking systems that host company career pages directly: Ashby, Workable, Greenhouse, Lever and their peers. The good roles are often only in one of them, and frequently it's the company's own page, which nobody checks daily.
Quarrion checks them daily. This is the least glamorous part of the product and arguably the most valuable per hour saved, because checking a hundred sources is exactly the kind of high-volume, zero-judgement work software should absorb.
Before any listing reaches you, it is probed to confirm the role is still open. Ghost listings — roles that were filled, cancelled or never real — are the most common complaint about job boards, and applying into one costs you an application's worth of effort for a guaranteed silence. Dead listings get filtered out at the door.
Scoring: judgement, not keyword counting
Every discovered role is scored against your CV. The scoring runs in tiers: cheap rule-based filtering first (wrong country, wrong seniority, duplicate of something already seen), then an AI pass that reads the posting the way a person would — what the role actually needs, whether your experience covers it, whether the gap is bridgeable or fundamental.
Roles that score well enough get a deeper research pass: the agent digs into the role and tags what it found, so a strong match arrives with context rather than just a number.
The score always shows its working. That is a design decision, not a flourish: a number you can't interrogate is a number you can't disagree with, and you will sometimes disagree with it. The breakdown is what lets you correct the agent rather than abandon it.
Tailoring: grounded in what you've actually done
For roles you want to pursue, Quarrion tailors your CV and drafts a cover letter per role. The tailoring is grounded in a structured profile built from your own CV — a knowledge graph of your actual roles, skills and accomplishments — which means the rewriting works by selection and emphasis, not invention. It can foreground the project that matters for this posting. It cannot give you three years of Kubernetes you don't have, because nothing in the source material says you do.
Made-up skills are a documented failure mode of AI CV tools, and the fix is architectural: if the generator can only draw from your verified history, the hallucination has nowhere to come from.
Applying: the agent fills, you approve
The agent fills real application forms — the tedious, repetitive part — and then queues the application for your approval. Nothing is submitted until you say so.
This gate is the load-bearing difference between Quarrion and the spray-and-pray blasters. An application an employer reads as personal should have had a person behind it at least once, at the moment of decision. Automating everything up to that decision saves the hours; keeping the decision keeps you honest, and keeps your name off the pile of obviously-automated applications that recruiters learn to skip.
After the application: the loop most tools drop
Applying is the middle of a job search, not the end. Quarrion tracks every application on a pipeline board from applied to offer, drafts recruiter replies and follow-ups in a unified inbox — each tied to the application it belongs to, so you never answer a call about a role you can't place — and helps with interview preparation and offer negotiation when things progress.
There is also a salary layer: city-level benchmarks adjusted for cost of living and inflation, with live exchange rates, so "is this offer good?" gets a real answer rather than a guess.
What it deliberately doesn't do
No application is sent without your approval. Your CV is not rewritten with skills you don't have. The agent doesn't apply to hundreds of roles to manufacture a feeling of progress — the scoring exists precisely so most roles never take up your attention at all.
The premise of the whole product is that the bottleneck in a job search was never how fast you could submit. It was reading four hundred postings to find the twenty worth an evening. Quarrion reads the four hundred. You read the twenty, approve what goes out, and take the interviews.
There is a free tier with no card required, which gets you scored roles in the first session. The paid tiers add volume, auto-apply and tailoring. Either way, the shape of the deal is the same: the agent does the reading, the drafting and the form-filling; the decisions stay yours.
