What it will not do, and what it cannot
This category is full of tools that will write you a CV claiming whatever the posting asked for. Those work, briefly, and then someone asks a question in an interview and the applicant has nothing. Dossier is the version that refuses. Four rules follow from that, and each one costs a feature people ask for.
It never claims something you have not confirmed
Not in a CV, not in a letter, not by implication, not by leaving something out and letting the rest imply it. If a posting requires something that is not on your confirmed list, it says so and asks.
This is enforced by a check in code that runs over every generated draft, not by an instruction in a prompt. A prompt is a request. A check is a guarantee.
What it costs: there is no one-click “optimise my CV for this posting”. There is a question in the middle, and sometimes the answer is no.
A tailored CV is a selection, never a rewrite
When it tailors, it chooses which of your real experiences to show and in what order. It cannot add an employer you did not work for or make a bullet sound bigger than what you told it, because there is no field those could travel through.
The gate is strong on names and advisory on prose
A requirement is either checkable or it is not. A tool, a certification, a licence, a language with a level, a named method, a degree, a years-of-experience floor — a screener can look for those, so those decide the verdict.
“Strong stakeholder management” and “thrives in ambiguity” are kept and shown to you, because they tell you what to emphasise. They never decide the verdict. Scoring them would be inventing a measurement, and an invented measurement looks exactly as confident as a real one.
You can read the file it keeps on you
Not a summary of it. The exact text sent on your behalf, verbatim, from inside the app. Every fact in it is editable and deletable, and the interview ends on a review screen rather than a confirmation.
What this is not
It is not a lie detector. You can tell the interview you know Kubernetes when you do not, and it will believe you. The guarantee is narrower than that, and worth stating precisely:
Dossier will never claim something on your behalf that you did not tell it you could do. It cannot check whether what you told it is true.
And one more, which is a product boundary rather than an epistemic one:
Dossier does not submit applications. It prepares them. The last click is always yours.
That is not a limitation to apologise for. Every tool that auto-submits is one policy change away from burning its users’ reputations, and the applicant is the one who has to explain it.
