What is a Custom GPT?
A Custom GPT is your AI assistant, fully attuned to your brand’s vibe, voice, and expertise. It’s like having a virtual team member who knows exactly how to engage clients, support your team, and share knowledge in a way that feels genuinely aligned with your brand. You can create multiple Custom GPTs for specific needs, like a LinkedIn Post Planner, Newsletter Writer, Content Calendar + Strategy Builder, and more.
👉 Unlike custom instructions, which just tailor ChatGPT’s responses to you, a Custom GPT serves as a dedicated tool for your business, delivering responses that fully embody your brand’s voice and expertise in whatever area you’d like it to support you in.

How to Set Up Your Custom GPT:
- Access ChatGPT on OpenAI:
- Head to chat.openai.com and log in. You’ll need the Pro plan to create a Custom GPT.
- Start Customization:
- In ChatGPT, go to Explore GPTs and select Create a Custom GPT.


- Set Up Key Instructions and Prompts:
- Customize Responses: Write a description and instructions that outline your brand’s tone and the specifics of what this specific Custom GPT should know.
- Example: If the Custom GPT is set up for generating LinkedIn posts
- “This GPT acts as a social media support team member specializing in LinkedIn content creation for Oui, We Studio. The primary focus is to develop detailed LinkedIn post plans based on provided content, aligning with the pillars: [X]. The GPT should draft posts using my distinct voice, incorporating a personal, engaging, and conversational style that aligns with the business's brand. Posts should be casual. It should respond to each request by outlining a clear post strategy, complete with exact copy, and ensuring the messaging resonates with the target audience. It should also be adaptable, taking into account various content areas provided by me and tailoring the messaging accordingly. The goal is to create professional, yet personable and authentic LinkedIn content that highlights expertise, insights, and current activities in a way that feels genuine and aligned with my voice. Do not use hashtags or marketing jargon words. Start each post with a short hook and format the post contents with a mix of short and long paragraphs. Give all post plans in a table format, post #, content pillar, post details, links. Do not use quotations when quoting my owns words - the only time to add quotes is for a podcast transcript.”
- Add Knowledge Points: Share details on your programs, any unique frameworks, or specific knowledge areas (like “Oui, We’s Human Design approach to content strategy”).
- Add Your Conversation Starters:
- Conversation starters set the tone and guide interactions within your Custom GPT.
- Examples:
- “Here's the latest update from my podcast; draft a LinkedIn post.”
- “I have new business insights; create a post plan for LinkedIn.”
- “Help me share what I'm currently working on in a LinkedIn post.”
- Include Knowledge Files
- The knowledge section in Custom GPTs is where you embed specific information, guidance, and context that the GPT can draw from in its responses.
- Examples:
- Program and Course Overview PDF’s
- Brand Voice and Style Guide PDF’s
- Key Concept or Framework PDF’s

- Test and Refine:
- Interact with your Custom GPT to see if it’s flowing the way you want. Tweak and refine until it feels like a true extension of your voice and style.

Tips for Using Custom GPTs Effectively:
1. Define Clear Role-Specific Prompts
- Set up prompts that speak directly to each specific task. For example:
- LinkedIn Posts: “Create a LinkedIn post on [topic] with an inspiring tone for female founders and include a question to drive engagement.”
- Newsletter Drafting: “Draft a weekly newsletter outline with sections for upcoming events, actionable tips, and a personal note.”
- Keep these prompts consistent so the GPT learns exactly how to respond for each type of content.
2. Integrate Your Brand Voice Guidelines
- Make sure your Custom GPT has clear knowledge of your tone and language style. Upload or describe your brand’s voice—whether that’s empowering, motivational, or relaxed—so it’s always consistent across different types of content.
3. Incorporate Seasonal Themes and Timely Topics
- Update the GPT with knowledge files or specific prompts based on seasonal themes, industry trends, or campaign focuses. For instance, as you approach the end of the year, prompt it with, “Generate LinkedIn post ideas that focus on goal setting and reflection for the new year,” to keep your content relevant.
4. Use It to Generate a Weekly or Monthly Content Outline
- For content planning, ask the GPT to outline post themes, weekly topics, or headline ideas that fit your goals. For example, you can prompt, “Create a content calendar outline for LinkedIn posts that includes a motivational Monday theme, mid-week tips, and a Friday reflection.”
5. Repurpose Across Formats Efficiently
- Use the Custom GPT to turn one content type into several variations. For instance, ask it to take a LinkedIn post draft and create a matching newsletter snippet or Instagram caption. This keeps content consistent and saves you time by leveraging your efforts across platforms.
