If you find yourself telling an AI chatbot the same background details every single time, “I live in Singapore, keep it brief, use British English”, there is a better way. Modern chatbots let you save those preferences once so they apply to every chat. Setting up ai custom instructions singapore users can enjoy more relevant, personalised replies without repeating themselves, and newer memory features take this even further.
This guide explains what custom instructions and memory are, how to use them well, and the privacy points you should keep in mind before you switch them on.
What custom instructions and memory do
Custom instructions are standing notes you give the chatbot about yourself and how you want it to respond. Think of them as a profile the AI reads before every conversation. You might tell it your location, your job, your preferred tone, or rules like “always answer in plain English” or “give me the short version first”.
Memory is a related but slightly different feature. Instead of you writing a fixed profile, the chatbot remembers useful details from your conversations over time, such as your name, ongoing projects, or preferences it has noticed. The next time you chat, it can draw on those saved details automatically.
Both features aim at the same goal: less repetition and more relevant answers. Instead of re-explaining that you want recipes suited to a small HDB kitchen, or replies in British English, you set it once and move on.

How to set them up well
Most chatbots keep these settings under a menu labelled “Custom instructions”, “Personalisation”, or “Memory”. The setup is usually just a couple of text boxes or a simple toggle.
When writing custom instructions, be specific and practical. Useful things to include:
- Context about you: your location, language preference, and rough level of expertise on common topics.
- How you like answers: short or detailed, formal or casual, with examples or without.
- Recurring needs: for instance, “I often plan meals for two”, or “I write for a Singapore audience”.
Keep it concise. A tight, clear set of instructions works better than a long ramble. You can always adjust as you learn what helps. Clear wording is a skill in itself, and our guide to prompt writing basics for AI tools applies here just as much as it does to one-off prompts.
For memory, the key is to review it now and then. Most tools let you see what the AI has saved and delete anything you would rather it forgot. It is worth checking this occasionally so the chatbot’s picture of you stays accurate and does not carry over stale details.
Privacy and safety points to keep in mind
Personalisation is convenient, but it means the AI tool is storing information about you, so a little caution goes a long way.
Be careful what you put in. Avoid saving sensitive personal data such as your NRIC number, passwords, banking details, or health information into custom instructions or memory. Once stored, that information sits with the service, and you cannot always be sure how it is handled. Treat these features like a public notebook, not a private vault. Our guide to AI and your privacy covers what to think about before sharing anything with an AI tool.
A few more sensible habits:
- On shared or family devices, remember that memory can carry your details into every chat, so keep personal notes out of it if others use the same account.
- Turn memory off, or use a temporary or incognito chat, when you are discussing something you do not want remembered.
- Review and clear saved memories periodically.
- Remember the usual rule: AI can be confidently wrong, so verify anything important and never rely on it alone for medical, legal, or financial decisions, no matter how well it seems to “know” you.
A practical wrap-up
Custom instructions and memory turn a generic chatbot into one that feels tailored to you, cutting out repetition and making answers more relevant. Set clear, concise preferences, review what the tool remembers, and keep sensitive personal data out of these features entirely. Used thoughtfully, they make AI noticeably more helpful in daily life while keeping you in control of your own information.
