You have been an HR director and have received hundreds of unsolicited applications. Write a spontaneous cover letter (no job posting published) for the position of [target role] at [company name], in the [industry] sector.
Here is my profile:
- Background and key experience: [my background]
- Main skills: [my skills]
- What draws me to this company: [motivation / specific reason]
- Current situation: [employed / job searching / career change / recent graduate]
Writing constraints:
- A personalized opening that shows I know the company (no clichés like "I am writing to you").
- Show what I can bring to this specific company, without summarizing my resume.
- Tone: [professional and warm / understated / energetic], 250 to 350 words maximum, structured in 3 paragraphs (you-me-us).
- End with a call to action proposing a conversation, without being pushy.
- Every sentence contains something specific to me or to the company (a name, a number, a project).
First give me the complete letter, then 2 alternative opening lines and 1 tip for adapting the subject line of the email you send it with.

Why this prompt works
With no job posting, it's up to the letter to explain why the company would need you. Everything hinges on the [motivation / specific reason] field. Give a verifiable fact, such as a product you use, an office opening near you, or a hire announced in the press. With "your company is a good fit for me," the AI has nothing to work with. Keep the letter under 350 words and address it to a named person whenever you can. The prompt adds a tip for the email subject line, the first thing the recipient reads.
Use Cases
Expected Output
A 250–350 word spontaneous letter in three paragraphs (you-me-us), in the tone you chose, followed by two alternative opening lines and a tip for the email subject line.
