🔍 In-Depth Guide

How to Set Up Custom Instructions in ChatGPT (Step-by-Step)

Open ChatGPT and click your profile icon in the bottom-left corner. Select 'Customize ChatGPT' u2014 you'll see two text boxes. The first asks: 'What would you like ChatGPT to know about you to provide better responses?' The second asks: 'How would you like ChatGPT to respond?' Fill both, save, and you're done. Every conversation from that point inherits this context automatically.nnFor the first box, include your profession, your location, your typical use cases, and your audience. For example, mine says I'm an AI consultant and trainer based in Dubai, working with real estate agents, business owners, and coaches across the GCC. I use ChatGPT for content, training scripts, client proposals, and GoHighLevel workflows.nnFor the second box, tell it your tone preferences and what to avoid. I tell ChatGPT to write in a direct, conversational tone u2014 no bullet-point overload, no academic language, no disclaimers about consulting professionals. You can also tell it your preferred output format: short paragraphs, numbered steps, tables. Get specific. Vague instructions produce vague improvements.

What to Actually Write in Your Custom Instructions (Real Examples)

This is where most people get stuck u2014 they write something like 'I am a business owner' and wonder why nothing changed. The quality of your Custom Instructions determines the quality of every response you get. Be specific enough that a freelancer reading it would know exactly how to work for you.nnHere's a real example from one of my GoHighLevel students who runs a marketing agency in Abu Dhabi: 'I run a digital marketing agency serving real estate developers and off-plan project sales teams in the UAE. My clients primarily want leads, WhatsApp automation, and social media content in both English and Arabic. I use GoHighLevel as my core CRM and automation platform. When I ask for copy, match Gulf market expectations u2014 professional but warm, not aggressive sales language.' That's it. After that, ChatGPT stopped giving him generic Facebook ad copy and started writing scripts his clients could actually use.nnFor the response style box, don't just say 'be concise.' Say 'give me the answer first, then explain if needed. Use short paragraphs. If I ask for options, give me three maximum with a clear recommendation.' That level of instruction cuts your editing time in half.

Combining Custom Instructions With Role Prompts for Even Better Results

Custom Instructions set your permanent context. But for specific tasks, you can stack a role prompt on top to push the output quality even further. This is what I call a 'layered prompt' approach u2014 and it's what separates people getting 70% usable output from people getting 95% usable output.nnOnce your Custom Instructions are in place, start a conversation with something like: 'Act as a senior real estate copywriter who specialises in off-plan property sales in the UAE. You understand that buyers are mostly overseas investors who need reassurance about ROI, payment plans, and developer credibility.' Then ask your actual question. ChatGPT now has two layers of context: the permanent background from your Custom Instructions and the task-specific role from your prompt.nnI use this method when building training content for my courses. My Custom Instructions tell ChatGPT I'm an educator. My role prompt for that session might say: 'Act as an instructional designer who creates course modules for non-technical adult learners in the Gulf.' The combination produces lesson outlines I can work with immediately instead of spending 20 minutes fixing generic outputs. Try this today: update your Custom Instructions, then open a new chat and lead with a role prompt for your next task.

📚 Article Summary

Most people use ChatGPT like a search engine — type a question, get a generic answer, move on. That’s fine if you want generic results. But if you’re using ChatGPT for your business, your clients, or your marketing, generic is useless. The trick that changed everything for me and my clients is dead simple: Custom Instructions.Custom Instructions is a built-in ChatGPT feature that lets you tell the AI exactly who you are, what you do, and how you want it to respond — before you type a single message. Think of it as giving ChatGPT a permanent briefing about your world. Instead of starting every conversation from scratch and watching ChatGPT give you advice meant for a generic American SaaS startup, it responds as if it already knows you, your industry, and your goals.I train real estate agents and business owners across Dubai and the Gulf on AI tools, and this is the first thing I show every client. One of my students — a property consultant in Downtown Dubai — was using ChatGPT to write WhatsApp follow-up messages for leads. The replies were stiff, full of American idioms, and sounded nothing like her. The moment we set up her Custom Instructions with her name, her agency, her typical client profile (high-net-worth investors, mostly from India and Russia), and her preferred tone, ChatGPT started producing messages she could actually send without editing. That’s the power of context.The reason this works is straightforward. ChatGPT is a prediction engine — it predicts the most useful response given what it knows. The more relevant context you feed it upfront, the more targeted its predictions become. Without Custom Instructions, it’s guessing your context every single conversation. With them, it’s operating with a full picture of who you are and what you need. You’re not making ChatGPT smarter in a technical sense — you’re making it smarter for you specifically.This isn’t a workaround or a hack. OpenAI built this feature specifically for this purpose. It’s available on free and paid plans. And yet fewer than 10% of ChatGPT users I’ve surveyed in my courses have ever touched it. Setting it up takes about five minutes. The return on those five minutes compounds every single time you open ChatGPT after that.

❓ Frequently Asked Questions

The most reliable way is to set up Custom Instructions in your ChatGPT account settings. This lets you provide permanent context u2014 your profession, location, audience, and preferred response style u2014 that ChatGPT applies to every conversation automatically. Users who fill in both Custom Instruction fields typically report needing to edit ChatGPT's output 40-60% less than before. It's free, takes under five minutes, and works on both free and paid plans.
Custom Instructions are a built-in ChatGPT feature that stores persistent context about who you are and how you want the AI to respond. Instead of re-explaining your background in every chat session, you write it once and ChatGPT remembers it for all future conversations. There are two fields: one for background information about you, and one for your response preferences (tone, format, length). The information is stored in your account settings under 'Customize ChatGPT' and can be updated any time.
Yes. Custom Instructions is available on both ChatGPT Free and ChatGPT Plus. OpenAI rolled it out to free users in 2023. The feature is found by clicking your profile icon in the bottom-left sidebar and selecting 'Customize ChatGPT.' There is no premium paywall on this specific feature, though Plus users get additional benefits like access to GPT-4o and longer context windows.
Use the second field in Custom Instructions u2014 the one that asks how you want ChatGPT to respond. Be specific about your tone (professional but conversational, direct, warm), your format preferences (short paragraphs over bullet lists, or vice versa), and what to avoid (no corporate jargon, no excessive caveats, no unnecessary disclaimers). You can also paste in 2-3 examples of writing you like and ask ChatGPT to match that style. The more concrete your instructions, the closer the output will match your voice from the first draft.
In the first box (about you), include: your job title, your industry, your location if relevant, your typical tasks in ChatGPT, and who your audience is. In the second box (how to respond), include: your preferred tone, your format preferences, what to avoid, and your typical output needs. For example, a real estate agent might write: 'I sell off-plan properties in Dubai to GCC and international investors. Write follow-up messages in a professional but approachable tone. Avoid pressure sales language. Keep responses under 200 words unless I ask for more.' That level of detail produces immediately usable output.
Absolutely u2014 and industry-specific Custom Instructions produce dramatically better results than generic ones. A real estate agent in Dubai should include details like their target buyer profile (first-time buyers vs. investors), the types of properties they deal in (off-plan, ready, commercial), and the communication channels they use (WhatsApp, email, Instagram). A marketer using GoHighLevel should mention the platform by name and describe their workflow. ChatGPT can then give advice, copy, and scripts that fit your actual situation rather than a hypothetical generic business.
Yes. Each of the two Custom Instructions fields has a limit of 1,500 characters. That's roughly 250-300 words per field u2014 enough for a solid briefing if you're concise. Prioritise the most important context: your role, your audience, your key use cases, and your response preferences. Avoid padding. If you find yourself hitting the limit, cut anything that's nice-to-have versus need-to-have. The most impactful information is usually your industry, location, and the specific tasks you use ChatGPT for most often.
