What the cover letter builder does
Matches your resume
The letter uses your resume’s header, fonts and colour, so the two look like a set when a recruiter opens them together.
Pick the job from your tracker
Choose a job you saved or applied to on Astra and the role, company and job description fill in for you.
AI first draftPremium
AI writes a short, specific letter from your resume and the job, using only what your resume says. It never adds a skill you do not have.
Word and PDF downloads
Download a Word file for job portals or a PDF for email. Both are real text that ATS software can read.
One letter per job
Each resume keeps its own letter. Craft a resume for a job, then write the letter for that same job right next to it.
Saved as you type
Your letter saves with your resume, in your account or in this browser, so you can come back to it any time.
How it works
1
Open your resume, or start a new one, and go to Cover letter.
2
Add the job, then write the letter or let Premium AI draft it.
3
Download it as Word or PDF with a free account.
Many recruiters skim a cover letter in seconds. Three or four short paragraphs about one job, with real results, beat a long generic letter.
Frequently asked questions
Is the cover letter builder free?
Yes. Writing a cover letter and downloading it as Word or PDF is free with an Astra account. The AI first draft is part of Astra Premium, along with the other AI tools in the resume builder.
How long should a cover letter be?
Three or four short paragraphs, about 200 to 350 words. Name the role and company, give your two or three strongest results that matter for this job, and close with your interest in talking.
Do freshers need a cover letter?
Not always, but it helps when an application asks for one, when you are changing fields, or when you can point to a project or internship that matches the job closely.
Will the AI make things up?
No. It writes only from what your resume says, and any sentence that names a tool or skill that appears in the job but not in your resume is removed before you see it. Read every line before you send it.
Should I send the cover letter as Word or PDF?
Upload Word (DOCX) on job portals, since ATS software reads it best. Attach a PDF when you email a recruiter, since it looks the same everywhere.
