How the builder works.
The tool opens with your strongest concrete result. It then builds a body from 1–3 specific achievements from your real experience, a paragraph on why this specific company, and a professional close.
Three tones (standard, enthusiastic, concise) combine with six situations — standard, career change, employment gap, referral, entry-level, and a short 100–150 word note for required-but-unread portal fields. Upload your resume to prefill your name and contact details and surface quantified lines worth reusing. Output is fully editable before you copy, or download it as .txt or .md.
Grounded beats invented.
A cover letter that names a skill or result you cannot back up does more harm than a plain one. Any AI writer that is not checked against your real history can add exactly that: requirements copied from the job description, or achievements you never gave it.
This tool does not generate claims. It structures what you tell it. If you write that you led a team of 5, that is what appears. If you do not, it does not.
When you want a draft tailored to a posting, the Jobsistant extension writes cover letters from facts saved in your Super Context and runs a fabrication check on the draft. You review the result before sending it.
The output contains only information you provided. Brackets like “[measurable outcome]” are prompts for you to add real numbers — not placeholders the tool fills with invented data.
Your information stays in your browser.
This tool does not upload, store, or transmit anything you enter. The cover letter is generated locally and can be copied directly to your clipboard. Analytics may record that the tool was used, subject to consent, but never the company name, achievements, or generated text.

Common questions.
How long should a cover letter be?
250–400 words on one page — roughly 3–4 paragraphs. The builder shows a live word count with a badge when you are in range. For portal fields that require text nobody will closely read, use the short-note option (~100–150 words).
What is a good cover letter opening line?
Lead with your strongest concrete result, not a declaration of interest. Name a result that shows what you can contribute to this role. This builder opens with your real achievement.
Should I write a cover letter for a career change?
Yes — it is one of the situations where a letter matters most. Select the career-change situation and the letter opens with your closest-fit achievement, then bridges fields without apologizing for the pivot.
Does my resume upload get sent anywhere?
No. The PDF is parsed entirely in your browser — it is only used to prefill your name, email, phone, and to suggest quantified lines you can reuse. Close the tab and it is gone.
Want a letter written for the posting itself?
This builder fills a proven template with what you type. Jobsistant drafts the letter from the job description and the experience already in your profile, so there is nothing to re-enter, and keeps it with that application. Tailored letters are Pro, free during early access.
