How to Build Your Own “Jennifer” — A Custom GPT Article Grader

How We Built Jennifer — The Article Grader That Fails Writers and Makes Them Better

Our “Jennifer” GPT grader keeps our writers honest. She grades ruthlessly, counts specifics, and enforces the blog posting guidelines that make our content sound like us, not like ChatGPT.

But because of OpenAI’s current sharing restrictions, only our team can access Jennifer directly. So in this guide, we’ll teach you how to build your own version from scratch, complete with grading logic, structure, and penalties.

Start With the Job Description

Before you write a single line of instruction, define the role.
Jennifer is a strict grader. That’s her entire job.

Give your GPT a clear, single-purpose identity, something like:

Name: “001 Jennifer – Article Grader”
Description: “Strict grader using clear, concise writing standards and content guidelines.”

That clarity tells the model how to think before it ever touches an article.

Build the Rubric

Most people write vague prompts like “Check for clarity and SEO.”
That’s amateur hour. A strong grader needs quantifiable rules.

Here’s the core of Jennifer’s rubric, you can copy and tweak it:

RulePenaltyWhy
Fewer than 10 specific examples (names, places, quotes)-1 letter gradeReal stories = trust
Fewer than 3 internal links to your own content-1 letter gradeBuilds EEAT & SEO
Salesy or “fluffy” toneMax grade = CReaders trust authenticity
Each typo or grammar error-1 letter gradeQuality is non-negotiable
ChatGPT giveaways (“doesn’t just do X, it also does Y”)-1 letter gradeSounds robotic
Overly long or vague writing-1 letter gradeBrevity = clarity

This converts subjective editing into objective math.
When your writers complain about grades, you can show them the receipts.

Write the System Instructions Like a Real Manager

Open the “Configure” screen of your custom GPT and paste your rubric as strict instructions.

Example core block (trimmed from our own):

Grade harshly. An A must be at the level of world-class journalism from a national
publication.
Less than 10% of submissions should earn an A.

Make sure the article fits the audience and topic of the site.
If a personal brand site, include relationship context (people, places, experiences).

If fewer than 10 specifics, drop a full letter.
If fewer than 3 internal links, drop a full letter.

Sales tone = C max.
Every typo = -1 letter.

If writing is unclear or wordy, -1 letter.
List counts of specifics and links in feedback.

That’s it. Short, strict, measurable.

Add Your Knowledge Files

Upload blog posting guidelines and Content Factory Workbook (or whatever your content bible is).
This gives the GPT context for your tone, linking habits, and structure.

Jennifer references this file automatically, which is why her feedback feels “on-brand” instead of generic.

Preload Smart Conversation Starters

These help your team use the GPT correctly without having to explain the rules each time.

Here are ours (and you should copy them verbatim):

  • “Grade this blog post from a team member on becoming Googleable.”
  • “Review this article for ChatGPT-like language.”
  • “Does this article meet our EEAT standards?”
  • “Is this post good enough to repurpose for localservicespotlight.com?”

These act like ready-made prompts that keep grading consistent.

Ban the “AI Giveaways”

Make your grader allergic to robotic writing.
We explicitly flag and penalize phrases like:

  • “In conclusion”
  • “Moreover / Furthermore / Nonetheless”
  • “X doesn’t just do Y; it’s also Z.”
  • “As a leading provider…”
  • “Cutting-edge solutions…”
  • “Holistic approach…”

Whenever Jennifer finds one, she automatically drops the grade.

And that’s exactly why our content keeps improving.
