Nothing invented
Every sentence rests on your CV. No motivational filler, no “highly motivated”, no “team player” — and no claim your data doesn’t back. What isn’t backed doesn’t make it in.
Cover Letter Generator
The cover letter generator that has read your CV
The cover letter generator doesn’t write a separate document. It uses the same context as your CV — everything the engine worked out about you and the role, including your CV and short profile — and turns it into your personal cover letter: three texts that belong together, each with its own emphasis. No filler, no invented sentences, only what your CV backs up. The result is a finished DIN 5008 page in your CV’s design — one coherent whole, editable right on the page.

Editing
The finished page is the editor
No text box next to a preview: you write directly on the rendered A4 page, exactly where it will sit later. Every save generates your cover letter anew — a new version with a freshly rendered PDF.
Recipient
Edit company, department, contact person and address right in the address window — where they later show through the envelope window.
Subject & job title
The subject line carries the position, bold per DIN 5008. Change the job title here and it flows through both documents: CV and cover letter share the same source.
Body text
Edit the entire letter right on the page — completely, paragraph by paragraph, word by word.
Of a piece
CV and cover letter, one layout
Your cover letter loads no template of its own. It takes exactly your CV’s layout — the same typeface, the same colors, the same accent, the same margins. Change something in CV Studio and it changes in both documents at once. There is no second cover-letter template to maintain separately.
One template, two documents
Both read the same layout. No setting things up twice, no style break between page one and the letter.
One change, both restyled
Switch color world or typeface in the studio and it restyles CV and cover letter in one move.
Your overrides carry over
Your own overrides too — margins, accent, decorators — carry cleanly into both documents.
Context
The same knowledge, three texts
Your CV, your summary and your cover letter aren’t three strangers. They draw from the same five sources — the job, your facts, your voice, the industry language and the company — and they’re written in sequence: first the role descriptions, then the summary, then the cover letter that has already read both. We always bring context along: every text knows what the engine worked out about you and the role beforehand. But a cover letter is not a CV in sentences — so the engine weighs each document differently.
-
In the CV
Every role gets its description — facts up front: responsibilities, numbers, results. Structure over narrative.
-
In the summary
The summary distills those same roles into one paragraph — the through-line the cover letter builds on.
-
In the cover letter
Your voice and the link to the company carry the text — backed by the same facts, just told more personally.
Verifiable
Not a prompt, a tool
What a generic AI text box can’t do. Four things that separate a real cover-letter tool from a chatbot.
Form that fits
Running text on a single page, no “I” opener, address window per DIN 5008, date right-aligned, subject in bold. The letter fits a window envelope without you measuring anything.
Tone and spelling checked
Whether the posting addresses you formally or informally, JACVault derives it from the ad — not guessed. The text then runs through a deterministic spell-check, not a second language model.
Editable, ATS-readable
The result is no image and no locked PDF: you edit it right on the page, and beneath the layout a machine-readable text layer remains — the same one an applicant-tracking system reads.
FAQ
Before you begin
Can I create a cover letter for free?
Yes. Your first complete application — CV and cover letter — is free, as a real PDF with no watermark. You only need a plan once you apply regularly.
How long is the cover letter?
One page of running text — short enough for the first seconds a recruiter spends, long enough to show the link to the role. Not an essay, not half a line.
Does the AI invent things about me?
No. Every statement rests on your CV. There are no motivational clichés and no invented achievements — what your data doesn’t back doesn’t appear in the letter.
Can I edit the text afterwards?
Yes, right on the rendered page. Edit the recipient, subject and the entire body where they sit. Every save generates your cover letter anew — a new version with a fresh PDF.
Does the letter use the right form of address?
JACVault derives the form of address from the job posting and its research on the target company — a start-up that says “du” gets an informal tone, a corporation a formal one. A deterministic spell-check then reviews the text.
Does the cover letter match my CV?
It uses exactly the same layout — typeface, colors, accent and margins are identical. There is no separate cover-letter template. Change something in CV Studio and both documents change at once.
Does the cover letter follow DIN 5008?
Yes. Address window, right-aligned date and a bold subject sit in the right places — the letter fits a window envelope without you measuring anything.
Is the cover letter available in English too?
Yes. At generation you choose the language yourself — or go by the language of the job posting. The letter then follows that language’s conventions.
