Set up ChatGPT custom instructions so it stops asking the same questions

Open ChatGPT and find your settings

Open ChatGPT in your browser or app. Look for a small circle with your initials or profile picture — usually in the bottom-left on the web version, or the top-left on the mobile app. Click or tap it once. A short menu slides open with options like Settings, Help, and Log out. From that menu, choose Settings (it may show a small gear icon ⚙️ next to it). If you don't see a profile circle, look for a ⋯ (three dots) menu or a ☰ (three lines) icon instead — those open the same menu on some devices. You'll know it worked when a Settings panel fills most of your screen, with a list of options down the side or stacked vertically.

Find the Custom Instructions area

Inside Settings, scan the list for a section called Personalization or a link that says Custom Instructions. OpenAI has moved this menu a few times, so if you don't see it right away, try Beta features, or scroll through the entire Settings list. On older accounts, you may need to flip a toggle called Custom Instructions to on before any boxes show up. When you find the right screen, you'll see two text boxes stacked on top of each other, each with a short label above it. You'll know it worked when both boxes are visible and ready to type into.

Tell ChatGPT about yourself

Click or tap into the first box — the one with a label like "What would you like ChatGPT to know about you to provide better responses?" This is where you write the facts ChatGPT should keep in mind: your job, your family situation, your skill level, your location, anything that comes up often. There is a soft character limit (roughly 1,500 characters per box), so pick the three or four facts that show up most in your chats. As you type, a small character counter at the bottom of the box will let you know how much room you have left. If you don't see a counter, just aim for 3–5 sentences.

If you find yourself writing a whole biography, stop and trim. The instructions should be specific, not exhaustive. Saying "I work in marketing" is more useful than "I have worked in many fields over my career."

You'll know it worked when your details are visible in the box and the character counter (if shown) is well under the limit.

Tell ChatGPT how you want it to respond

Now click into the second box — the one with a label like "How would you like ChatGPT to respond?" This is where you shape the tone, length, and format of every future reply. Think of it as giving ChatGPT a small style guide. The more concrete you are, the more consistent the replies will be. Treat vague wishes like "be helpful" as a starting point, not the final answer. "Short paragraphs, no emojis, give me the answer first and then the explanation" will travel much further.

If you're not sure what to write, start with one sentence — "be friendly and brief" — and come back later to add more. You'll know it worked when your style preferences appear in the second box.

Save and turn it on

Look for a Save button at the bottom of the panel, or a Done button on the mobile app. Click or tap it once. Some accounts also have a toggle labeled Enable custom instructions for new chats — if you see it, make sure it's switched on (it usually glows or turns blue when active). If you don't see a toggle, the Save button is enough. A small confirmation may appear at the top, sometimes just a checkmark. From this moment on, ChatGPT will quietly read both boxes at the start of every new conversation.

You'll know it worked when you close the Settings panel, reopen it, and your two boxes are still filled in. If they are empty, the save didn't stick — try again.

Open a fresh chat and test it

Close the Settings panel and click the New chat button (usually a pencil icon ✏️ or a "New chat" label at the top). Ask a small, everyday question — the kind where your saved facts should clearly show up. The reply should feel like it was written for someone who already knows you, not a stranger who just met you.

If the answer ignores your instructions, the wording is probably too vague. Rewrite it to be more specific — "15-minute dinners" instead of "quick dinners." You'll know it worked when the reply sounds like the ChatGPT you wanted all along.
