The result to aim for
Thomas, 40 years old, employed in aeronautics, wrote a cover letter with the AI: two hours instead of one day. He starts with a first jet, asks for a more powerful form, and "has the feeling that this letter is my letter".
What was done
The Echos Weekend (Sarah Dumeau, 12 March 2025). Thomas advises against "starting with a white leaf": "I gave him a first jet and asked him to reconsider the shape by being more striking. The journalist is testing two prompts. First, too vague ("write me a cover letter for a Community Manager position in a BTP company): correct form, trivialities. Second, advised by recruiter Olivier Bonnefous: role, company achievements, values, "how my profile could stick" — "a good working base". Distinct from practice `lettre-motivation-sur-mesure`. The two hours are Thomas' estimate, unaudited.

Act as a cover letter specialist. My goal: to be contained at I'm like, "K2" It's like, "K3" or "K4". This is my first jet (made, without inventing): Rewrite it to show how my profile fit their values, being more riding on shape. If an achievement is missing, say so. Invent no experience.
