Short job posts of 1 to 300 words pull 8.4% more applications per view than average, according to LinkedIn's own posting data - LinkedIn Talent Blog.

Keep that number in mind, because it is the single biggest reason most AI-written job descriptions underperform. Left alone, a large language model will happily hand you 900 words of confident, well-structured, thoroughly average prose. It is longer than what works, and it took you eleven seconds to make.

So the skill is not "getting AI to write a job description." Any model does that. The skill is constraining it, feeding it the things it cannot know, and knowing which parts of the job are worth handing over at all. This guide covers the prompt structure that actually works, the tools worth paying for (with real prices), and the claims about AI and hiring bias that do not survive contact with the research.

What AI actually changes, and what it does not

The useful framing is that AI has collapsed the cost of the first draft to roughly zero, and changed nothing else. ChatGPT, Claude and Gemini will all produce a competent, structurally complete job description from a job title in seconds. That draft is genuinely worth something: writing from a blank page is the slowest part of the task, and the part recruiters procrastinate on most.

What has not changed is everything that makes a job description work. The model does not know your compensation band, why the last person in the seat left, what the team is actually like on a Tuesday, or which of your listed "requirements" are real. Those are the details candidates say they care about most, and they are exactly what AI cannot invent. Used well, AI gives you:

1. Consistent structure across every posting, without a style guide nobody reads
2. A fast first draft that you edit down rather than write up
3. Role and industry framing for titles you have never hired before
4. Reduced biased language, if you ask for it explicitly (see the caveat below)
5. Scale, when you are posting twenty roles instead of two

Note what is missing from that list: eliminating bias. This is the most oversold claim in the category and it deserves a straight answer. The foundational study here, Gaucher, Friesen and Kay (2011), found that masculine-coded wording ("competitive", "dominant", "leader") made roles measurably less appealing to women, driven by a weaker sense of belonging rather than perceived ability. That effect is real. But a 2024 replication in the Strategic Entrepreneurship Journal reproduced it for start-up job ads and not for established firms, which tells you the effect is context-dependent rather than a universal dial you turn with a prompt. Cleaning up gendered wording is worth doing. Believing it removes bias from your hiring process is not the same thing, and a language model has no visibility into the screening decisions where bias actually costs people jobs.

Mastering the Art of Prompt Engineering

Prompt quality is the whole game, and the highest-leverage instruction in the entire prompt is a word limit. Models default to long because length reads as effort. Candidates read on phones and bail. Given LinkedIn's finding that posts over 601 words beat the average by only 1%, while short posts beat it by 8.4%, capping your prompt at 300 words is not a stylistic preference: it is the difference the data actually supports.

Beyond length, a good prompt is mostly an act of supplying context the model has no way to guess. The difference between a generic output and a usable one is almost never the model. It is whether you told it the salary band, the three things that make the role unusual, and who the description is trying to repel as much as attract.

Elements of an Effective Prompt

1. Role-specific details: job title, department, and the 3-5 responsibilities that actually consume the week
2. Company information: the real culture, not the values page. Include what is hard about working there
3. Required qualifications: separate genuine must-haves from wish-list items, and tell the model to keep only the must-haves
4. Compensation: the band, in numbers. 61% of candidates rate salary range as the most important element of a post
5. Unique selling points: the one true thing a competitor could not copy into their own ad

That fourth item is the one teams skip, and it is the most expensive omission on the list. Where pay transparency is not yet mandated, posting a band is still the cheapest conversion improvement available to you, and no amount of prompt refinement substitutes for it. The fifth item is the honest test of whether you have written anything at all: if your "unique selling point" would read identically in a competitor's posting, you have written filler, and the model will happily generate more of it.

Sample Prompt Structure

Generate a job description for a [Job Title] at [Company Name]. Include:

1. A brief company overview (2 sentences maximum)

2. Key responsibilities (5 bullet points, the ones that fill the actual week)

3. Required qualifications (must-haves only, no wish list)

4. Compensation range: [X to Y]

5. Benefits and perks (only the ones that are genuinely above market)

6. Equal opportunity statement

Tone: [Professional/Casual/Enthusiastic]

Hard limit: 300 words. Do not exceed it. Avoid masculine-coded language such as "competitive", "dominant", "rockstar", "ninja".

Refining Your Prompts

The first output is a starting point, not a deliverable. The techniques below are ordered by how much they improve results in practice, and the first one matters far more than the rest.

1. Feed it your best example: paste in a job description that produced great candidates and tell the model to match its voice and length
2. Iterative refinement: start basic, then instruct in edits ("cut 100 words", "make requirement 3 less intimidating")
3. Adversarial pass: ask the model which requirements would deter a strong but non-traditional candidate
4. Keyword incorporation: supply the terms candidates actually search for, since the model guesses at these

The adversarial pass is the technique most people never try and the one that changes outputs most. Language models are agreeable by default and will validate whatever you hand them unless you explicitly instruct them to attack it. Asking "which of these requirements are unnecessary gatekeeping?" reliably surfaces the eight-years-experience line that nobody in the team actually meets. That is a genuinely useful second opinion, and it costs one extra message.

Creating a Template Prompt for Consistency

Once your prompt works, the win is not the description you just wrote. It is never writing that prompt again. A template prompt stored somewhere your team can reach turns a personal trick into a process, and it is the point at which AI stops being a party trick and starts saving real hours.

The mechanics are simple, but the discipline is where teams fail: the template only stays useful if someone owns it and updates it when the boilerplate changes. Treat it like a document with a maintainer, not a snippet in someone's notes app.

1. Start with a comprehensive base: your best-performing prompt, including the word limit
2. Use placeholder text: bracket the variables ([Job Title], [Department], [Band])
3. Incorporate company boilerplate: the EEO statement and legal language, written once
4. Define customization points: mark clearly where role-specific truth must be inserted
5. Assign an owner: one person keeps it current, or it silently rots

In practice, most teams find the template does something they did not expect: it standardizes their hiring managers, not their AI. The bracketed fields force a manager to state the band and the real must-haves before anything gets generated, which is the conversation that was always the actual bottleneck.

Leveraging AI Tools for Job Description Enhancement

Now the honest question: do you need a dedicated tool at all? For most teams, the answer is no. A good template prompt and a general-purpose model cover it. Dedicated tools earn their keep in two specific situations: when you are posting at volume and need consistency enforced rather than requested, and when the description needs to land in the system that publishes it rather than in a chat log.

What follows is the current state of the category, with prices where they are published. Be warned that this is a market with an unusual amount of stale information in it, largely because listicles keep recommending products that no longer exist.

1. Textio

Textio is the original augmented writing platform, and still the most sophisticated: it scores drafts against outcome data rather than a wordlist, predicting how the language lands with women and people of color. If your problem is genuinely about language quality at enterprise scale, nothing else on this list is doing the same thing.

Two caveats matter. Textio publishes no pricing whatsoever, so it is a demo-and-negotiate purchase, which usually means it is not aimed at your budget if you are hiring under twenty roles a year. And the company's investment has visibly shifted toward performance and interview feedback in recent years, with the recruiting product no longer the centre of gravity it once was.

2. Ongig

Ongig is the job description management tool, focused on bias detection, readability scoring, and keeping a library of every JD your company has live. It is the only serious player here that publishes list prices, which is worth respecting.

Those prices tell you exactly who it is for. The Lite tier is $4,900 per year (up to 100 jobs, 3 users), Professional starts at $14,900 per year for unlimited jobs plus AI writing, and Enterprise starts at $39,900. Ongig also sells a JD bias audit from $6,900 as a standalone engagement. If you are a ten-person recruiting team with a sprawl of 400 inconsistent legacy descriptions, that Lite tier is defensible. If you post six roles a year, it is roughly $800 per job description.

3. Manatal

Manatal takes the opposite approach: rather than a specialist writing tool, it is a full applicant tracking system with an AI job description writer built into the job creation flow. You draft from a job title and a few keywords, edit in place, and it publishes to your careers page and job boards without a copy-paste step.

It is on every plan, including the $15 per user per month entry tier, which makes it roughly two orders of magnitude cheaper than Ongig's floor. The trade-offs are documented in Manatal's own support docs: English only, 200 generations per month per account, and locked until your first payment clears. It also does nothing Textio does on the analysis side. It is a competent generator attached to the place the job actually lives, which for most small teams is the trade worth making.

4. HeroHunt.ai

HeroHunt.ai comes at the problem from the other end. Rather than optimizing the description to attract inbound applicants, its AI Recruiter uses the role definition to source and contact matching candidates from over 1 billion profiles directly. That is a different bet: it is for roles where the applicants you want were never going to read your posting in the first place. It is free to start, with no credit card required.

A note on Skillate

If you find Skillate on a list of AI job description tools, that list is out of date. Skillate was acquired by Sense in September 2022 and its technology was folded into that platform rather than sold standalone. It is a useful test to run on any tool roundup you read in this category: check whether the vendors still exist independently before you shortlist them.

Best Practices for AI-Generated Job Descriptions

The practices below assume the draft is done. Everything that determines whether the posting works happens after the model finishes, which is the inverse of how most people allocate their attention on this task.

The first item is not a formality. AI-generated text is confident and fluent regardless of whether it is accurate, and a job description is a document candidates make life decisions against. Fluency is not correctness, and nobody will catch an invented benefit except you.

1. Human oversight: verify every factual claim about the role, pay, and benefits. Models invent plausible perks
2. Cut, do not add: your edit pass should reduce word count. If it grows, you are drifting away from what works
3. A/B testing: run two versions where volume allows, and change one variable at a time
4. Compliance check: pay transparency rules vary by jurisdiction and change often. AI does not track this
5. Personalization: add the specific, unglamorous detail about the team that no model could have guessed

On timing, one small thing worth knowing: 57% of applications arrive Monday through Wednesday, with Monday the strongest day. Posting a finished description on a Friday afternoon costs you nothing in effort and a measurable amount in reach, which makes it one of the few free wins in this entire process.

Measuring Success and Iterating

Most teams never close the loop, which is why their job descriptions never improve. The metrics below are worth tracking not because they are novel, but because without them you are editing on taste, and taste is exactly what the LinkedIn length data suggests recruiters get wrong.

Pick two of these rather than all five. A metric nobody looks at is worse than no metric, because it creates the impression of measurement.

1. Applications per view: the cleanest signal of whether the description itself is working, isolated from traffic
2. Quality of applicants: the share of applicants who clear your screen
3. Time-to-fill: measured against your own baseline, not an industry benchmark
4. Candidate feedback: ask new hires what the posting got wrong. They will tell you
5. Drop-off point: where readers stop, if your ATS or careers page exposes it

Applications per view is the one to start with. It separates the description's performance from your distribution, which raw application counts do not: a bad post on a big board can beat a good post nowhere, and you will draw exactly the wrong conclusion. Track it for a quarter, feed the winners back into your template prompt as the example the model should match, and the loop starts compounding.

The summary is unglamorous. AI writes the draft, you supply the truth, and the word limit does more work than the model choice. A recruiter with a 300-word cap, a real salary band and one honest sentence about the team will beat a 900-word AI masterpiece every time, and it takes less effort to produce.
