It started with a LinkedIn connection. Mitch Sullivan and I connected, and not long after, I spotted his new tool: Mitchs.ai. A job advert generator? You bet I was going to test it.
I love trying new tools in the job description and job advert space, especially with all the AI buzz flying around. If there’s something that promises to make writing job postings faster or better, I’m here for it.
Step 1: I chose a job title
We usually use “Marketing Manager” when testing job description tools, so I stuck with that here too. It’s a good baseline — mid-level, popular, and a role most recruiters are familiar with. (I also used it in my recent test of ChatGPT AI job description generators.)

Step 2: I tested Mitchs.ai
The interface is simple. I filled out the “Job Details,” “The Why,” and the “Call to action”. Then I choose US English and Medium word count (between 250-300 words). Then I clicked “Review” and within seconds, I had a complete job advert.

It wasn’t too generic. It has personality. And it avoided the usual buzzword soup most job postings swim in. It read like a real person wrote it. Not bad for version one.
When you sign up for Mitchs.ai, you get one free credit, which I think is a great way to test things out before you buy. Speaking of, there are a few pricing options:
After your free test, it’s £10 per job ad. If you’re posting regularly, subscription plans start at £39/month with bundles of credits that roll over. Plans scale up to support teams of up to 20 users, and include free recruiter training on job briefs and copywriting (£369.00/month).
Step 3: I analyzed my free job advert in Ongig’s Text Analyzer
Of course, I couldn’t resist throwing it into our Text Analyzer. Our platform scans job postings for readability, tone, length, and bias. Mitchs.ai’s version did pretty well (79.1%/100). The tone was conversational, with no complex words and no confusing abbreviations. But it had a couple of areas with suggestions (e.g., no benefits listed and some gender-coded words).

Step 4: Mitch Sullivan reached out with Version 2 of the job advert
Here’s the wild part. Mitch himself DM’d me. He’d seen the first version and said, “Let me take another swing at it.”
So now I had version two — hand-edited by Mitch Sullivan himself. It included benefits (and I didn’t even tell Mitch how it scored in Text Analyzer, yet). I ran that one through:

The score increased to 74% out of 100. One abbreviation was added (PTO — which is not too confusing, so I’m ok with it!). It also leaned a tiny bit more masculine-coded based on the wording. The usual “masculine-coded” suspects were there (“lead” and “strong”), which I see all the time in job postings. We’ve found (and so has research) that removing gender-coded words helps increase applications from qualified candidates.
Step 5: The verdict on Mitch’s job advert

Both versions were solid for a first pass. But writing one job advert is very different from managing dozens or hundreds across a team.
That’s where Ongig helps. We analyze (write and rewrite) job postings, and we give you a way to scale the whole process.
Build from custom templates, store different versions, keep everything in one job library, sync with an ATS, and add workflows so your team can collaborate without stepping on each other. Whether you’re starting from scratch or refining something like Mitchs.ai’s output, Ongig helps you manage job content at scale.
In my opinion, tools like Mitchs.ai are great for ideation and fast writing. You get a running start. Then you can bring it into Ongig to analyze, improve, templatize, and store.
Why I Wrote This
I get asked all the time: “What tools do you use to write better job ads?” I wrote this to share one I actually tried. Mitchs.ai is impressive, and I think it’ll help a lot of recruiters. And, the real magic happens when you combine it with Ongig — so you can test, improve, and manage every job advert like it matters (because it does).
