# AI cover letter written from your real experience

> Resume Builder AI writes a cover letter of about 250 to 400 words from your resume or notes and the job ad, using Claude Sonnet 5. It opens with the role and your strongest relevant result, connects your experience to the posting's main requirements and closes with a clear next step. Its rules forbid inventing experience or facts about the employer: unknown names and details appear as [placeholders]. A letter costs 200 credits plus 1 credit per pasted word.

Paste your resume or notes and the job ad. Get a one-page cover letter that connects two or three of your real results to what the employer asked for, without the filler openers.

## What the AI cover letter does

- **Specific, not generic**: It opens with a real result from your notes instead of 'I am writing to express my interest'.
- **Matched to the posting**: Two or three of the job's main requirements, each paired with evidence from your experience.
- **No invented employer facts**: It does not research the company; add one true reason you want the job, or fill the [placeholder] it leaves.
- **The right length**: Three or four short paragraphs that fit on one page with your contact details.

## How to write a cover letter with AI

1. **Paste resume and job ad**: Your resume or notes first, then the posting.
2. **Add your reason**: One line on why this employer; otherwise you get a [placeholder] to fill.
3. **Edit and send**: Fill the placeholders, add the hiring manager's name if you know it and read it aloud.

## What makes a cover letter worth reading

Hiring managers skim. A letter earns attention in its first two sentences by naming the role and showing one result that proves you can do it. The middle connects what the posting asks for to what you have done, one requirement at a time. The close says why this employer and asks for a conversation. Everything else is optional.

A free structure you can fill in by hand:

- [Your Name] | [Email] | [Phone]
- [Date]
- Dear [Hiring Manager Name],
- Opening: the role you are applying for and one result that shows you can do it.
- Middle: two requirements from the posting and the experience that meets each one.
- Closing: one specific reason you want this employer, and a request to talk.
- Sincerely, [Your Name]

## Phrases to cut

These fill space without telling the reader anything:

- I am writing to express my interest in
- I believe I would be a great fit for this role
- I am a hard-working team player
- I am passionate about [anything], without evidence

## AI cover letter FAQ

### Is it okay to send an AI cover letter?

Yes, if every statement is true and it sounds like you. Read it aloud, replace any phrase you would never say, and add one detail only you know, such as why this employer matters to you.

### How long should a cover letter be?

Usually 250 to 400 words: three or four short paragraphs on one page. Follow the posting if it asks for something different, such as a short note in an application form.

### Does it research the company for me?

No. It uses only what you paste, so it cannot make claims about the employer. Add one true reason you want the job, or fill the [why this employer] placeholder it leaves.

### Is the AI cover letter generator free?

The template and the phrases list on this page are free. A generated letter uses purchased credits: 200 credits per document plus 1 credit per pasted word, so a resume and job ad of 500 words cost 700 credits. New accounts get no free credits; registration is free.
