DAY 3 CHALLENGE

AI For Senior HR Professionals Challenge

Build Your Custom HR AI Co-Pilot (Custom GPT)

This is the day everything clicks.

See Today's Challenge

Let’s anchor how far you’ve come

Today is different. Today is big.

Because now we take all that power and package it into your own Custom HR GPT. This becomes your AI HR Co-Pilot – a living, breathing tool that you and your team can use every day to execute HR work at a much higher level, much faster.

See Today’s Challenge

Today’s goal

By the end of today, you will have:

A tool that never sleeps, never gets tired, never complains, and never breaks character. Save it. Share it. Scale it across your HR function. Today you stop “experimenting with AI”… and start deploying it inside HR.

See Today’s Challenge

What we re building today

In the next few minutes, you’ll set up a CustomGPT that:

Combines your HR System Prompt and Tone Blueprint into one permanent tool.
Can be used by anyone on your HR team with zero AI expertise.
Never forgets your instructions, context, or preferences.
Lives at a shareable link you can bookmark and distribute.
Becomes an always-available HR execution engine.

This is the next level.

This is where it all comes together.

The Problem You Still Have…

Even with strong HR System Prompts, there is friction. You know the pattern.

You need to:

What happens?

You go find the document that has your system prompt.
You copy the prompt.
You paste it into ChatGPT.
You modify.
You generate.
You tweak.

Your HR Officer or Business Partner wants to use it?

Same headache:

By the third time, many HR people quietly think:

“Let me just write it myself.”

The prompts work. But they are not yet scalable. What usually happens:

You invest an hour building a fantastic System Prompt for, say, Performance Improvement Plans.
It works beautifully. You’re impressed.
The following week, you forget exactly where it’s saved.
Your team doesn’t know it exists.
So you go back to manual drafting.

Or your HRBP pings you:

“Please resend that AI prompt thing we used last time.”

You become the bottleneck. Now imagine this instead:

Your HR team has a single link called: “Please resend that AI prompt thing we used last time.”
They click it.
It already knows your tone, expectations, HR standards, and system prompt.
They just type: “Draft a first warning letter for an employee…”

No searching. No copy-paste. Just instant access to your HR brain, codified. That’s a CustomGPT.

How Far You Can Take This (HR Use Cases)

I use this logic all the time. Think of CustomGPTs as specialised HR assistants, each with a clear purpose.

Examples (you can build these over time):

“HR Diplomacy Coach”

Helps you reframe emotionally charged responses into firm but professional HR communication—especially for sensitive issues (discipline, union matters, executive pushback).

“Policy Pro – [Your Organisation]”

Drafts, reviews, and updates HR policies using your tone, structure, and compliance requirements.

“Performance Letter Assistant”

Creates PIPs, warnings, performance summaries, and feedback notes aligned with your standards.

“EXCO HR Summary Writer”

Takes raw HR dashboards or notes and turns them into clear, structured summaries for CEOs/Boards.

“L&D Program Architect”

Helps design learning programs, outlines, session descriptions, and evaluation forms.

Let’s take an example similar to “Write Nice Dan” but tailored to HR.

Example: “Calm, Firm HR”

Many Senior HR leaders in Africa operate in highly charged environments:

You might type something like:

“This behaviour is completely unacceptable. You’ve ignored three reminders, missed two critical deadlines, and are undermining the team. If this continues, we’ll have no choice but to take disciplinary action.”

“Calm, Firm HR” could transform it into:

“Over the last four weeks, we have raised concerns about missed deadlines and incomplete deliverables on three separate occasions. This pattern is now impacting the team and overall performance. This is a formal reminder that these expectations are non-negotiable. Please treat this as an opportunity to reset and demonstrate improvement. If this pattern continues, we may need to escalate to formal disciplinary procedures in line with company policy.”

That’s what CustomGPTs can do for HR:

They don’t just save time. They prevent HR errors that can become legal, cultural, or reputational problems.

Important: ChatGPT Plus Required

To build CustomGPTs, you need ChatGPT Plus (currently ~$20/month).

For any serious HR leader, the answer is obvious.

If you don’t have it yet, this is a good time to upgrade—especially if you intend to:

Today’s Challenge

EXERCISE 3

Build Your Custom HR GPT

Here’s the shortcut:
If at any point you feel stuck, ask ChatGPT to guide you through each step.

Today, you’re going to take the System Prompt you created on Day 2 and turn it into a CustomGPT that you and your team can use forever.

We’ll assume your Day 2 System Prompt was for something like:
“Executive HR Memo / Briefing Note Writer”
(If it was for another HR task, that’s fine—the steps are identical.)

Step by Step Exercise

Modify Your HR System Prompt for CustomGPT Use

Open a fresh ChatGPT window and paste this prompt:

Modify this HR system prompt so that it functions as the core “Instructions” for a CustomGPT that will be used by multiple HR stakeholders:

[PASTE YOUR PREVIOUS HR SYSTEM PROMPT HERE]

The updated version should assume:
Different HR users (CHRO, HRBP, HR Manager, HR Officer) may use it.

They will provide context about their organisation, country, sector, issue, and audience.
The CustomGPT must always:
- Maintain my HR Leadership Tone Blueprint.
- Keep outputs legally and culturally sensitive for African contexts.
- Communicate clearly with non-HR executives and employees

Please rewrite the system prompt accordingly so I can paste it into the “Instructions” section when creating my CustomGPT.

ChatGPT will refine and slightly re-frame your system prompt to:

Copy the new Instructions and keep them ready.

Start Creating Your Custom HR GPT

Inside ChatGPT:

Click “Explore GPTs” on the left menu.
In the top right, click “Create GPT.”

You will see two options: Create and Configure.
You are not starting from scratch—you already have your instructions.
So you’ll use Configure.

Configure Your HR GPT

In the Configure tab:

1. Give it a Name

Example:

2. Give it a Description

Example:

“When given HR context and key facts, draft executive-ready HR memos, summaries, and recommendations aligned with our tone, standards, and African operating realities.”

3. Paste Your Instructions

In the Instructions field, paste the updated HR System Prompt from Step 1. Optionally, you can:

Test It (With a Real HR Scenario)

Use a real HR issue to test. Prompt example:

“We are a Nigerian financial services company with 1,200 staff. Voluntary turnover among mid-level relationship managers has risen to 24% in the past 12 months, compared to 12% company average. Exit interviews show themes of workload, leadership style, and lack of career progression. I need a one-page EXCO memo that:

Summarises the issue clearly.
Highlights business and people risk.
Recommends 3 practical HR interventions.
Suggests clear next steps for EXCO.
Draft in my HR leadership tone.”

Read the output:

If not, go back into Instructions and refine:

Test again until it feels 90–95% right.

Finish, Set Access, Share with HR Team

Once satisfied:

You now have:

Share the link with:

When you update the Instructions in future, every user will automatically work with the latest version. You’ve just built an HR system that saves you 10–20 hours per month—minimum.
