Effective Custom Instructions for ChatGPT:
A Guide for Business Professionals
1. Introduction
What Are Custom Instructions?
Custom Instructions are a powerful feature in ChatGPT that lets you teach the AI about your preferences and how you want it to work. Once set up, these instructions apply to all your ChatGPT conversations.
By telling ChatGPT about yourself and how you prefer to communicate, you can get more personalized and relevant responses. Plus, you won’t need to repeat background information in each conversation. This is especially useful for business professionals who want consistent, high-quality interactions.
Why They Matter for Business Professionals
For business professionals, Custom Instructions can save a lot of time. Whether you’re a marketer, a consultant, or a leader, you can make sure the AI aligns with your unique style and goals. This makes your workflow more efficient and improves the overall quality of your interactions with ChatGPT. Custom Instructions allow you to set the tone, style, and focus, making the AI a valuable part of your professional toolkit.
2. Understanding Custom Instructions
What Are Custom Instructions?
Think of Custom Instructions as a way to give ChatGPT a consistent background of information and preferences. This way, every time you chat, ChatGPT already knows your preferences and can tailor its responses accordingly.
How Do They Work?
When you set Custom Instructions, ChatGPT automatically includes them in its responses. For example, if you tell ChatGPT, “I am a project manager in the tech industry” and “I prefer concise, data-driven responses,” it will remember this and respond accordingly. It provides a more personalized and relevant interaction by “remembering” these settings.
Benefits of Using Custom Instructions
- Consistency: Maintain a consistent tone and style across all your interactions.
- Time-Saving: No need to provide the same context in every conversation.
- Enhanced Personalization: Adapt to your specific needs and preferences.
- Improved Efficiency: Align responses with your professional goals, spending less time editing.
Where Do You Setup Custom Instructions?
Custom instructions are found in ChatGPT under the user profile CUSTOMIZE option. Follow these instructions to access them.
- Go to https://chatgpt.com/ (make sure you are logged in!)
- Click on your user profile icon in the upper right corner
- Click on “Customize ChatGPT”
- You will then see the Customize ChatGPT popup window for Custom Instructions.
3. Elements of Custom Instructions
What to Include in Custom Instructions
Custom Instructions have two main sections:
- What would you like ChatGPT to know about you?
- How would you like ChatGPT to respond?
Detailed Breakdown
1. What would you like ChatGPT to know about you?
This section functions as a mini bio where you provide relevant information about yourself, your role, and your interests. The goal is to give ChatGPT enough context to tailor its responses to your specific situation.
Examples:
- Name and professional title: “My name is Julie Holmes. I’m a keynote speaker and strategic advisor on Technology, AI and Innovation.”
- Professional focus: “I specialize in practical applications of AI for enhancing business strategy, sales, and productivity.”
- Interests and areas of expertise: “I enjoy discussing technology trends, innovation strategies, and AI implementation.”
- Personal preferences: “I prefer to focus on the positive uses of AI along with clear, actionable insights that aren’t full of technical jargon.”
2. How would you like ChatGPT to respond?
In this section, you outline your preferences for the AI’s tone, style, and formatting. This ensures that ChatGPT’s responses align with your communication style and meet your expectations.
Examples:
- Tone and formality: “Respond in a friendly, conversational manner, avoiding unnecessary complexity.”
- Style: “Use straightforward language and an active voice. Incorporate a touch of humor to keep the tone light-hearted.”
- Formatting preferences: “Use markdown for clarity, including headings, lists, and tables where appropriate. Avoid verbosity and ensure smooth transitions.”
4. Custom Instructions in Action
It might be helpful to see for yourself how custom instructions impact the output you’d get from ChatGPT.
Below are two different sets of custom instructions and the output that was generated by each one when given the same exact prompt.
Scenario 1: Alex
What would you like ChatGPT to know about you? | My name is Alex Green, and I am a digital marketing manager specializing in social media campaigns for tech startups. I have over 10 years of experience in the industry and enjoy creating engaging content that drives brand awareness and conversions. |
How would you like ChatGPT to respond? | Use a professional yet approachable tone. Provide data-driven insights and actionable recommendations. Format responses with bullet points for easy reading and include relevant industry examples where applicable. |
Output when asked, “What are some ways that I can improve my day-to-day work?” |
Scenario 1: Sam
What would you like ChatGPT to know about you? | My name is Sam Taylor, and I am a project manager in the software development industry. I lead cross-functional teams to deliver high-quality software products on time and within budget. I am interested in agile methodologies and continuous improvement. |
How would you like ChatGPT to respond? | Use my name when you talk to me, and be very encouraging. Respond with a concise, formal tone and provide analogies and examples wherever possible to improve my understanding. Use project management terminology and provide step-by-step solutions. Include references to agile practices and methodologies. |
Output when asked, “What are some ways that I can improve my day-to-day work?” |
As you can see, with just a few words about their background and how they want ChatGPT to talk to them, the content of the replies and the format/style of writing drastically changes to be more relevant and appropriate for them.
5. Tips for Creating Effective Custom Instructions
Strategies for Simplifying the Process
Creating effective Custom Instructions doesn’t have to be complicated. Here are some strategies to streamline the process:
- Use Pre-Written Templates: Starting with a template can save time and ensure you cover all necessary elements. Customize the template to fit your specific needs.
- Step-by-Step Approach: Break down the process into manageable steps. First, focus on what you want ChatGPT to know about you. Next, define how you want it to respond. This makes the task less overwhelming.
- Keep it Concise: Stick to the most relevant information. Remember, you have a 1500-character limit for each section, so prioritize clarity and brevity.
Common Pitfalls to Avoid
While creating Custom Instructions, be mindful of these common pitfalls:
- Overloading with Irrelevant Information: Include only the information that will help ChatGPT provide better responses. Avoid unnecessary details that don’t contribute to your goals.
- Confusing Instructions: Be clear and specific. Vague or contradictory instructions can lead to inconsistent or unsatisfactory responses. Ensure your instructions are straightforward and easy to understand.
Examples of Well-Crafted Instructions

By following these tips and avoiding common pitfalls, you can create Custom Instructions that effectively tailor ChatGPT’s responses to your needs, enhancing both the efficiency and quality of your interactions.
6. Best Practices for Custom Instructions
General Guidelines
Creating effective Custom Instructions involves a balance of clarity, relevance, and personalization. Here are some best practices to keep in mind:
- Clarity and Conciseness: Ensure your instructions are clear and to the point. Avoid unnecessary details that might confuse the AI. Be specific about what you want ChatGPT to know and how you want it to respond.
- Relevance to Your Goals: Focus on information and preferences that directly impact the quality and relevance of ChatGPT’s responses. Think about your primary use cases and tailor your instructions to support those objectives.
- Personalization: Incorporate personal and professional details that help ChatGPT understand your unique context. This can include your role, industry, interests, and specific requirements.
Best Practices
- Using Detailed and Specific Language: The more specific you are, the better ChatGPT can tailor its responses. Avoid vague statements and provide detailed descriptions of your preferences.
Example: Instead of saying, “I like detailed answers.”, say something like, “Provide comprehensive, in-depth responses with examples and data to support key points.”
- Aligning with Business Objectives and Strategies: Ensure your instructions support your broader business goals. Whether it’s driving sales, enhancing customer service, or improving internal communication, align your instructions to reinforce these objectives.
Example: “Focus on providing actionable insights that can help improve our customer retention strategies.”
Advanced Strategies
To get the most out of Custom Instructions, consider implementing these advanced strategies:
- Leveraging Brand Voices: Adopt well-known brand voices to ensure consistency and alignment with your professional tone. For example, if you admire HubSpot’s engaging and informative style or AppSumo’s casual yet persuasive tone, mention these in your instructions.
Example: Adopt a tone similar to HubSpot’s blog: engaging, informative, and slightly conversational.
- Adapting Instructions for Different Contexts: Tailor your instructions for various scenarios. For instance, you might need a formal tone for client communications and a casual tone for internal team updates. Update your instructions accordingly.
Example: For client emails: Use a formal and professional tone. Provide clear and concise information. For team updates: Use a casual and friendly tone. Keep it informal and engaging.
- Setting Verbosity Levels: Control the length and detail of ChatGPT’s responses by specifying verbosity levels. You can use different verbosity settings depending on the context and your needs.
Example:
Verbosity = 1: For concise summaries or brief responses.
Verbosity = 2: For a concise summary that is slightly more detailed.
Verbosity = 3: For standard, detailed responses.
Verbosity = 4: For in-depth explanations with examples.
Verbosity = 5: For comprehensive and detailed analysis.
- Using “Start the Output With” Elements: With this command as part of your Custom Instructions, you’ll get a table of information at the start of every output. This will allow you to see and understand the assumptions and context ChatGPT is working with, enabling adjustments as needed. Include these key elements at the beginning of each response for clarity and alignment.
Example (written to output as a table at the beginning of each output):
Start Response With:
| Field | Description |
|—|—|
| **Domain** | The broad business/topic area the task relates to |
| **Expert Role** | Within the domain, the specific expert role most relevant to the task. |
| **Goal** | A description of the objective and most appropriate verbosity level. |
| **Assumptions** | Any assumptions about the user’s intent, context, and underlying question. |
| **Methodology** | Any specific methodology that will be used to answer the query. |
Below is an example of what that output would look like.
- Have a library of Custom Instructions: If you work in multiple departments or with a variety of clients, you can use the library approach. Create multiple sets of custom instructions (saved in a document) that you can swap out as needed for various tasks. Of course, this is a bit more work, but it can be easier in the long run than trying to override a single custom instruction that isn’t relevant to a task you are working on.
- Use your Custom Instructions with other Generative AI platforms: While we love ChatGPT, it isn’t the only tool. While tools such as Claude, Perplexity, Gemini and others may not have the exact same functionality, you can still use your Custom Instructions on a chat-by-chat basis just by copying and pasting them or by creating simplified versions of them that you can use with other tools.
Maintaining and Updating Instructions
- Regular Reviews: Periodically review and update your Custom Instructions to ensure they remain relevant and effective. Your needs and goals might evolve, and your instructions should reflect those changes.
- Incorporating Feedback: Pay attention to the responses you receive and adjust your instructions based on what works well and what doesn’t. Experiment with different phrasings and details to optimize the AI’s performance.
- Keeping Up with New Features: Stay informed about ChatGPT’s new features and capabilities. As the platform evolves, new customization options might become available, offering more ways to enhance your instructions.

***END BEST PRACTICE GUIDE***
You will walk the user through both custom instructions fields one at a time:
1) What would you like ChatGPT to know about you?
2) How would you like ChatGPT to respond?
You will always start the conversation by explaining who you are and what you do followed by a list of questions that they could answer that would help you to build the necessary custom instructions. You will ask them 10 questions (keeping in mind that they are thought leaders, professional speakers, trainers, coaches and similar) to help them build a robust response to: “what would you like ChatGPT to know about you?” Remember that each of these fields can only accept a maximum of 1,500 characters so keep your answers clear and effective but concise.
You will always present the final custom instructions as regular output PLUS as a downloadable/copyable markdown so that it can be copied and pasted into the custom instructions fields easily.
The output you generate for the field “How would you like ChatGPT to respond?” should always have this text appended to the end exactly as it is written inside the quotes:
“Verbosity Levels:
V=0: One-liner.
V=1: Concise summary.
V=2: Brief overview.
V=3: Standard detail.
V=4: Detailed explanation with examples.
V=5: In-depth analysis with comprehensive details.
1. Start response with:
|Attribute|Description|
|–:|:–|
|Domain > Expert| {the broad AREA or DOMAIN the question falls under} > {within the DOMAIN, the specific EXPERT role most appropriate for getting the best output given the context or nuance of the question}|
|Goal|{ qualitative description of current assistant objective and VERBOSITY }|
|Assumptions|{ assistant assumptions about user question, intent, and context}|
|Methodology|{any specific methodology assistant will incorporate}|
2. Return your response, and remember to incorporate:
