Most people are using ChatGPT at maybe 20% of what it can actually do, and it's not because the tool is weak. It's because nobody ever told you where the real settings live.
I'm an engineer by training, but AI didn't come naturally to me either. I've had to sit down and actually go looking for these settings myself, the same way I'm about to walk you through them right now. This is one of those things that feels like it should be common knowledge and just isn't, because ChatGPT out of the box is built for everyone, which really means it's built for no one in particular. It's generic by default. These four settings are what actually personalize it.
Here's the full breakdown, and if you're someone trying to learn AI for beginners, this is a genuinely good place to start.
Setting one is Custom Instructions. Go to Settings, then Personalization, and turn it on. This is a plain text box where you tell ChatGPT directly how you want it to respond to you. You can tell it to sound more human, to remove em dashes if that's a pet peeve of yours, or to stop automatically agreeing with everything you say, which is a real pattern worth breaking since AI models are trained to be agreeable by default. Whatever you write here applies to every single chat going forward, not just the one you're in.
Setting two is Memory. It lives in the same Personalization menu. This is what stops you from having to explain who you are, what you do, and how you like information delivered every single time you open a new conversation. Once it's on, ChatGPT remembers your role, your ongoing projects, your preferences. You stop repeating yourself, and the answers start feeling less like they're coming from a stranger.
Setting three is Apps and Connectors. This one is bigger than people realize. You can connect Gmail, Google Calendar, and Notion directly. Once connected, ChatGPT can actually reference your real data from those apps instead of giving you generic, hypothetical answers. We're talking about your actual calendar, your actual documents, your actual inbox, not a guess at what a typical calendar might look like.
Setting four is Data Controls. Go there and turn off "Improve the model for everyone." This stops your conversations from being used to train future versions of the model. Your data stays yours. This is the one people skip because it feels technical, but it takes fifteen seconds and it matters.
None of these four settings make ChatGPT smarter in some abstract sense. What they actually do is make ChatGPT know who it's talking to, which sounds small until you feel the difference in the quality of every single answer that comes after.
Small settings. Compounding advantage. That's really the whole idea, and it's part of a bigger framework I call the AI Skill Stack, something I go deeper into in the book I'm working on right now.
If you want the exact custom instructions I personally use, word for word, comment SETTINGS and I'll send them straight to you. Copy them, adjust them until they sound like you, and make them yours.
This is Episode 3 of 8 in my AI Toolkit series, and next up I'm showing you what happens when you combine Memory with a Project, because that's genuinely where this starts to get powerful. Follow along so you don't miss it.
