# Tailoring a CV and letter

> How Careers tailors a CV and cover letter for one posting from your master profile: key qualifications, the truth check, languages, versions and the offline engine versus your AI.

For each posting Careers stores **one content version**: the fullest CV and letter that fit the posting, with a priority on every part that can be left out. A design then draws it at the length and density you choose.

## What it does

1. Extracts the posting's requirements.
2. Explains the match: covered with evidence, missing never claimed.
3. Chooses three to five **key qualifications**: your own statements and statements derived from your facts (such as whole years in the freelance role and its industries), plus up to two proof lines for must-haves you cover.
4. Selects and orders your lines. Everything keeps the id of its source.
5. Writes the letter from the same facts.

## The truth check

The check runs on every saved CV and letter.

- **CV**: a line with no source, a number that is not in its source, or a skill not on your list is refused or put back to the source line.
- **Letters and e-mails**: checked sentence by sentence. Numbers, years of experience, skills, employers, titles, credentials, achievements, spoken languages, contact data and the signature must trace to your profile or the posting. A failure refuses the save and names each sentence and why. Opinion, such as "I am excited about this role", is free.

## Languages

A German posting gets a German CV and letter, built from your own German lines. A Dutch posting gets English documents with one controlled line saying that you write in English. Dutch is written only for a profile that lists it above basic. A letter is never machine-translated.

## Offline engine or your AI

| Mode | Label | What it is |
|---|---|---|
| Offline engine | Offline engine | Deterministic, in your browser: selects, orders and lightly rephrases your lines |
| Your AI's rewrite | Your AI's rewrite | Your own AI rewords a version through Geenius OS and saves it. The check still applies |

An AI rewrite **inside the app** belongs to the AI features of Premium and Max, which are switched off in early access.

## Versions

Editing a version is the same CV. A new tailoring is a new version. An unsent application follows each new version; a sent one keeps the version it went out with.

## Counting

A tailored CV is counted once per posting, when it is first tailored. Deleting one gives nothing back. See [Plans and limits](/docs/plans-and-limits/).
