Personal AI Context File: What to Include + Free Template

What is a personal AI context file?

A personal AI context file is a plain-text record of who you are, how you work, and what you want assistants to know — written by you, not inferred from past chats. ChatGPT has Custom Instructions and Memory. Gemini has instructions and native memory. Claude has Projects and global Memory. None of them ship a portable, vendor-neutral context schema.

The practice is emerging from users who are tired of re-explaining themselves every time they open a new chat or switch tools.

What belongs in it vs what belongs in chat

Put standing rules and slow-changing facts in your context file: response style, role, active projects with dates, constraints that shape every answer. Keep one-off tasksin the conversation — "draft this email to Alex" does not belong in permanent memory.

OpenAI's own split mirrors this: explicit information goes in Custom Instructions; conversational details may land in Memory. A context file is the authored version of that explicit layer — but portable.

Section-by-section guide

• About me: Basics that ground every response — timezone matters for scheduling advice.
• How I want you to respond:Tone, length, format. This replaces repeating "be concise" in every chat.
• Work & skills: What you do and what tools you actually use — not a résumé, a working context.
• Current priorities: Date-stamp these. Stale priorities are how AI gives outdated advice.
• Preferences & constraints: The specifics generic memory misses — knee pain, school holidays, dietary needs.
• Things to avoid: Assumptions you do not want the model to make.

Privacy-first checklist: what NOT to include

• Passwords, API keys, authentication codes, or financial account numbers
• Medical or legal details unless truly necessary for the task
• Third-party private information without consent
• Anything you would not put in a shared Google Doc link

Research on ChatGPT's built-in memory (arXiv 2602.01450) found that inferred memories often capture more than users intend, including psychological inferences. An explicit, user-authored file reduces surprise.

Where to store it

A notes app or Google Doc works for drafting. AIMemLink hosts the same plain-text record at a fetchable URL — private link for full context, optional public profile for basics discoverable by username. You edit on the web or append via Telegram; the link always points to your latest version.

How to connect it to ChatGPT, Claude, and Gemini

Paste your AIMemLink instruction snippet into each tool's standing instructions (ChatGPT Custom Instructions, Claude project or profile instructions, Gemini personal context). The snippet asks the model to fetch your URL and use it as background for the conversation. See the provider setup guides for step-by-step paths.
