Free AI Job Description Generator

How the AI job description generator works

Enter the role

Job title is the only required field. Level, department, and location are optional, but each one you fill in makes the draft more specific to the job.

Generate and review

Add your work email and the draft streams onto the page in seconds. We send a copy to your inbox so you can find it later. No account, no credit card.

Edit, copy, post

Read it the way a candidate would. Fix anything that does not match how the role really works at your company, then copy the text into your job board or careers page.

What a strong job description includes

Whether you write it by hand or start from an AI draft, a job description that attracts the right applicants covers five things:

Job title and summary. A title candidates actually search for, plus two or three sentences on what the role is for and why it exists.
Responsibilities. Five to eight bullets describing the real work, written as actions. "Own the monthly close" tells a candidate more than "participate in finance operations".
Requirements. The few skills someone genuinely needs on day one. Every requirement you add filters people out, so keep the must-haves short and honest.
Nice-to-haves. Separate these clearly, so strong candidates who match the must-haves do not rule themselves out over the extras.
Company, pay, and logistics. A short company blurb, the work model (onsite, hybrid, remote), and a pay range where the law requires one, which now includes several US states.

Run that checklist against any draft, including the one this tool writes. The parts an AI cannot know about your company, the real must-haves, the pay range, the team the role sits in, are the parts worth your time.

How to get a better draft

The output is only as specific as what you type in. Four things help:

Use the real title. "Senior Accountant" and "Accounting Manager" are different jobs and produce different drafts. If your internal title is unusual, use the market title candidates search for.
Set the level. Pick the level you will actually hire at, so the draft asks for the right depth of experience. An entry level posting should not read like a director search.
Add the location and work model. "Austin, TX (Hybrid)" tells the draft, and later the candidate, exactly what flexibility looks like. Say what you mean here; vague work-model language costs you applicants.
Name the department. Context changes wording. A data analyst in marketing and a data analyst in finance do different work with different tools.

Why use an AI job description generator

The honest reason is the blank page. Most job descriptions get written under time pressure by copying an old posting that was itself copied from an older one. The requirements pile up, nobody remembers why "must have experience with X" is in there, and the result reads like every other posting in the category.

A generator resets that. You get a clean, structured first draft in seconds, written in plain language, and you spend your time on the part only you can do: deciding what the role really needs and what your company will offer for it.

It also keeps hiring managers consistent. When every manager starts from the same structure, your postings stop varying wildly in tone and format between departments.

What it will not do

It will not decide your requirements, set your salary, or know that your "Customer Success Manager" opening is really a renewals role. It drafts; a person who knows the job decides. That split is how we think about AI across hiring, and our guide to AI for recruiting maps where it helps and where people stay in charge.

Frequently asked questions

Is the AI job description generator really free?

Yes. There is no account to create and no card to enter. We ask for a work email so we can send you a copy of your draft, and that is the whole trade.

Do I need to sign up or install anything?

No. The generator runs in your browser on any device. Type a title, add your email, and generate. The full HRStak workspace is a separate product and a separate decision.

Can AI write a job description on its own?

It can write the draft on its own. It cannot know your team, your pay range, or which requirements are genuinely must-have. Treat the output as a strong first pass, then have someone close to the role review it before it goes live.

How long should a job description be?

Long enough to cover the summary, responsibilities, requirements, and logistics, and no longer. For most roles that fits on one page. Candidates scan postings the way you scan resumes, so the second page rarely gets read.

What roles does it work for?

Any title you can type, from entry level to VP, across every function. It is not limited to a template library. Each draft is generated for the specific title, level, department, and location you enter.

Can I use the output in my ATS or on a job board?

Yes. The copy button gives you plain text you can paste into any ATS, job board, or careers page. HRStak is not an applicant tracking system, so the generator is built to work alongside whatever you already post jobs with.
