Custom Instructions: Build Your Own Personal AI Assistant
Learn how to set up Custom Instructions so your AI always knows who you are, what you do, and how you like to be helped — without repeating yourself every time.
What Are Custom Instructions?
Custom Instructions are like a permanent memory for your AI chatbot. Instead of explaining who you are and what you need every single time you start a new conversation, you write it once — and the AI remembers it forever.
Think of it like leaving a note for a personal assistant before you leave for the day. When they arrive in the morning, they already know how you like things done. Custom Instructions work the same way. You set them once, and every conversation starts with the AI already knowing your context.
You can tell the AI things like your job, your goals, how you want it to talk to you, and what you need help with most. Once set, it sticks — across every single chat.
Stop Repeating Yourself — Make AI Work For You
Most people start every AI conversation the same way: "I'm a middle school science teacher" or "I run a small online store selling handmade candles." Every. Single. Time. That's a huge waste of energy, and it means the AI never really gets to know you.
Custom Instructions change that. When you set them up, you turn a generic chatbot into your AI — one that already knows your world before you even type your first question.
Here's the thing: the more context an AI has about you, the better it can help you. A lawyer and a video game developer need totally different things from the same AI tool. Custom Instructions let the AI adapt to you, not the other way around.
💡 Key Insight
Custom Instructions aren't just about personal preference — they're a force multiplier. The better your AI knows you, the less back-and-forth you need, and the faster you can get real work done.
Three Steps to Your Personal AI Setup
Setting up Custom Instructions is simple. Here's how it works:
Step 1: Write Who You Are
Tell the AI about yourself. Your job, your experience level, your goals. Be specific — this is the foundation the AI will build on.
Step 2: Set How You Want to Be Helped
Explain your communication style, your preferences, and what kind of help you need most. Do you want short answers? Detailed ones? Code examples?
Step 3: Save and Start Chatting
Save your instructions in your AI's settings. Now every conversation begins with the AI already knowing you. No more introductions needed.
A Real Custom Instruction You Can Copy
Here's what a Custom Instruction looks like in action. This one is for a freelance writer who works with tech startups:
// My Personal AI Setup You are my personal writing and productivity assistant. About me: - I run a freelance writing business - My clients are mostly startups and tech companies - I work from home and am most creative in the mornings - I charge premium rates and value my time highly How you should help: - Keep responses short and action-focused - Suggest tools and workflows, not just advice - Flag when something might take more than 30 minutes - Be direct — I don't need gentle reminders
With this one-time setup, every new conversation starts with the AI knowing exactly who it's dealing with. No more repeating "I'm a freelance writer" ever again.
