Hundreds of texts in one go
AI rewrites all the vacancies in one spreadsheet in one go. Nobody has to rewrite the existing texts by hand, one by one, any more.

What it is
Derec is a Dutch staffing agency for education, with hundreds of vacancies that each have a text of their own. When the house style changes, all those existing texts have to be written again. I built a solution that lets AI rewrite the texts of a whole spreadsheet of vacancies in one go, and sends the result back by e-mail.

What it improves
The same structure for every text
Every vacancy text gets the same five parts, written by the same instructions. Candidates find the same information in the same place in every vacancy.
Existing vacancies in the new style too
A new house style can be carried through to the vacancies that already exist, not only to new ones. Old and new texts no longer drift apart.
The problem
BEFORE
Existing vacancies stayed in the old style
New agreements about the style and structure of a vacancy text apply to new vacancies straight away. The vacancies that already exist have to be rewritten by hand, one by one. With hundreds of vacancies that does not happen in practice, and old and new texts stay side by side.
THE USUAL SOLUTION
Why not vacancy by vacancy in a chat
The usual solution is to have AI rewrite each text separately in a chat. That works well for a few vacancies, but with hundreds the copying and pasting itself becomes the manual work. That is why the starting point was batch processing: one file with all the vacancies, processed as a whole.
The solution
THE SPREADSHEET
One file with all the vacancies
The input is a spreadsheet with one vacancy on every row. Nothing more is needed.

THE TEXT
AI writes five fixed parts
For each vacancy, AI writes the introduction, the job, the organisation, what the candidate brings and what the candidate gets. The details of the vacancy itself stay unchanged.

THE RESULT
The same spreadsheet, new texts
The result is the same spreadsheet, with the new texts in place of the old ones.

CONTROL
Nothing is published automatically
The rewritten texts come back as a file; the tool posts them nowhere by itself. A colleague reads them and decides which texts the team takes over. That keeps the team in control of what candidates get to read.

What it runs on
- Chat interface with file uploadTakes the spreadsheet and confirms straight away that the work has started.
- Job queueProcesses every vacancy in the background as a task of its own.
- LLM with fixed instructions (prompt)Writes every text in the same five parts.
- E-mailSends back the spreadsheet with the new texts.
The payoff
The tool was delivered to Derec in October 2025. It was made for the moment when many existing vacancy texts have to be revised at the same time.
