Four beats, one line.
A chat window invents a paragraph. The coach is bound to the job and to the document.
- 01Create a free account, paste the job
Paste the job description, or just the job title. The coach checks it against the resume you already have.
- 02See where you stand
Every must-have graded. Covered, partial, or missing — with a citation into your lines, not a generic score.
- 03Answer one question
It asks for what is missing, in plain language. A rough number is fine. Nothing is invented.
- 04The line goes on the page
You see it written in your words. You can undo its latest change. Then the cover letter and the interview use the same posting.
The difference is the line it writes.
Same fact Claire already had. The coach asked for the number, then put it on the page.

Zillionn AI, answered.
- What is Zillionn AI?
- Zillionn is ResumeStudio's AI coach. Create a free account and paste a job posting; it grades your resume against that job, then asks one question at a time and writes each line in your words. Cover letter and interview practice come from the same posting.
- Does the AI make things up?
- It's built to write only from what you tell it, and you can undo its latest change.
- Is Zillionn AI free?
- Yes, on a free account. Daily AI credits on the free plan cover the coach, and no card is asked for. Upgrade to Pro if you are applying to several roles at once and need a larger allowance.
- How is this different from ChatGPT?
- A chat window will write whatever sounds like a resume. The coach is bound to the job you pasted and the document on the page. A fact does not count until it is written, and you can undo its latest change.
- Can I start from a resume I already have?
- Yes. Import a PDF, then paste the posting. The coach grades that resume against the job instead of starting from a blank page.
- Will it write a cover letter too?
- Yes. The letter quotes the resume — the same wins, in the same voice — written to the job in front of you. Interview practice uses that posting as well.
