How to Use ChatGPT's Memory Feature to Save Time Every Day

Have you ever sat down to write an email or plan a weekly dinner menu, only to realise you have to explain your background, dietary needs, or writing style to your AI assistant all over again? It can feel a bit like introducing yourself to a coworker every single morning.

Thankfully, you no longer have to start from scratch every time you open a new window. With ChatGPT's memory feature, the assistant can remember details and preferences across all of your chats, making your daily tasks much smoother.

Here is how the memory system works and how you can use it to build a highly personalised assistant.

Understanding how AI memory works

In the past, AI assistants operated strictly within a single conversation. Once you closed a chat or hit "New Chat", the system forgot everything you had just discussed. This is because of the context window (the temporary memory space an AI uses to process your current conversation).

With the memory feature, ChatGPT can store key details from your chats and carry them over to future conversations. Think of it like a digital notepad where the AI scribbles down important facts about you—like your job, your pet's name, or how you prefer your weekly reports formatted—so you do not have to type them out every single time.

How to teach your assistant your preferences

You do not need any technical skills to start using this feature. In fact, you can train ChatGPT's memory just by having a normal conversation.

Here are two simple ways to set your preferences:

1. Let it happen naturally

As you chat, the AI will automatically pick up on details it thinks are useful for the future. For example, if you write, "I am planning a birthday party for my eight-year-old son, Leo," the AI might quietly note down that you have a son named Leo who is eight. The next time you ask for gift ideas, it will already know his age.

2. Give direct instructions

You can explicitly tell the system what to remember. This is the quickest way to set up your assistant. You can type a prompt (the instruction or question you give to the AI) like this:

• "Remember that I run a small boutique plant shop."
• "Remember that I prefer short, bullet-pointed summaries instead of long paragraphs."
• "Remember that our family is vegetarian and we do not eat mushrooms."

How to view and manage what the AI remembers

It is easy to keep track of what the AI has saved, and you have complete control over this information.

If ChatGPT remembers something incorrect, or if your circumstances change, you can manage these memories in two ways:

• Just ask it to forget: You can type, "Forget that I work in marketing," and the AI will instantly delete that piece of information.
• Use the settings menu: Click on your profile icon, go to Settings, select Personalisation, and then click on Manage Memory. Here, you will see a neat list of everything the AI has saved about you. You can click the bin icon next to any memory to delete it permanently.

Wrap-up

Teaching your AI assistant about your preferences removes the friction of repeating yourself, allowing you to get helpful, customised answers much faster. By taking just a couple of minutes today to share a few details about your work or daily routine, you can turn a generic tool into a highly personalised assistant. Open up a chat today and tell ChatGPT a few things you would like it to remember for your next project.
