Custom Instructions let you tell ChatGPT facts about yourself and how you want it to respond — once, permanently, across all future conversations. Go to Settings → Personalization → Custom Instructions, fill in the two text boxes, and save. ChatGPT applies these to every new chat automatically. No need to re-explain your role, tone preferences, or formatting expectations in every session.
GPTs are customized versions of ChatGPT built for specific tasks — a coding assistant, a writing coach, a customer support bot. Find them in the GPT Store at chat.openai.com/gpts. Click any GPT to open it and start chatting. Creating your own GPT requires a ChatGPT Plus account; using public GPTs is available on the free plan. No code required to build one.
ChatGPT Memory lets the AI remember facts about you across conversations — your job, preferences, ongoing projects — without you repeating yourself every time. Enable it at Settings → Personalization → Memory. You can view, edit, or delete individual memories at any time. Memory is separate from conversation history and works across all devices on the same account.
