It reads the posting itself
Paste a link from Jobs.ch, JobUp, LinkedIn or Indeed and the requirements are pulled out and matched against your CV — no copy-and-paste, no retyping.
Still rewriting every cover letter?
Your cover letter, written in about 5 minutes
Every posting wants different wording, different keywords and a different reason you are the right person — so the letter you sent yesterday is no use for the one you found today.
Add your CV once and paste the job posting. You get a letter written for that specific role and that specific company — not a template with your name dropped into it.

Download it
The letter arrives written against that posting, ready to send as a PDF. Want to change the wording? The Word version downloads too — on every account — and you edit it in Word or Google Docs.
Why it does not read like a template
A generic letter is obvious to whoever reads it. These are the parts that make the difference.
Your language, your tone
German, French, Italian or English on every plan, with five writing tones. Swiss orthography is handled properly, including ss instead of the sharp s.
Yours to change afterwards
The PDF is ready to send from the first free run, and the same letter also downloads as an editable Word file — free on every account — so any wording you want to reword you reword in Word or Google Docs.
Check the fit before you spend anything
A CV match check reads your CV against the posting and tells you where you are short, for a tenth of what a generation costs. It exists so you can walk away from a bad fit before paying for the letter, not after.
And four more documents, at no extra cost
The same run also produces the application email, 20 interview questions, a job summary and the archived posting. One cost, five documents — there is nothing extra to click.
Example output — fictional candidate
A cover letter it actually wrote
Generated end to end for a fictional candidate from a real Swiss posting — and the posting itself, archived. Open either at full size and read it.

No posting to hand right now?
You do not need to go and find a vacancy first. Loading one of the example jobs is free and costs no credits, so you can see the whole flow before you commit to a real posting. Writing the letter from it counts like any other run — the free plan includes two of them, no credits needed.
What is different afterwards
- Your letter answers the posting point by point, so a recruiter can see the match without hunting for it.
- The evening you used to spend rewriting is spent applying to the next one instead.
- Nothing is lost between applications: the posting is archived and the application is tracked for a year.
- The free plan includes 2 complete applications, one interview session and a free run of every AI tool — with no payment details.
- Built for the Swiss market and hosted in Zurich, with AI processing kept in the EU.
- Your documents are stored encrypted and are never used to train AI models.

Why not just use ChatGPT?
A fair question, and the answer is not that it writes badly. It is that it starts from nothing every time, and an application is more than one document.

The same goes for Claude, Gemini, Copilot or Perplexity — this is not about which one writes best, but about what a tool remembers between one application and the next. Training defaults vary by product and plan, and most let you opt out.
