Building Your ChatGPT Context Files

ChatGPT works best when it already knows who you are, what your business does, and how you like to write. Instead of re-explaining yourself every chat, build three small reusable context files — and you don't write them yourself. You give ChatGPT a prompt, answer its questions, and it writes each file for you.

What are the three context files?

Plain-English definition: a ".md" (Markdown) file is a simple text file with headings that AI tools read easily.

Once built, they're used two ways:

• Uploaded to a ChatGPT Project, so every chat in that Project has them as file context.
• Saved to memory with one extra prompt, so the key facts follow you into regular chats too.

How do I create aboutme.md?

I want to create an "aboutme.md" file that you can use as background context in every conversation we have. Ask me questions one at a time to build it — cover my name, my role/title, what I'm responsible for day to day, my working style (e.g. how much detail I want, how direct to be with me), my current priorities, and anything I frequently need help with. Once you have my answers, write the final file in clean markdown with headers.

ChatGPT will interview you — just answer naturally.

How do I create mybusiness.md?

Now let's build "mybusiness.md" — the standing facts about my business that you should always know. Ask me about: what we do and who we serve, our products/services, our pricing model, our team size and key people, our busiest season or cycle, our biggest current goal, and anything that's commonly misunderstood about the business that you should never get wrong. Then write the final file in clean markdown.

How do I create myvoice.md?

Bring 2–3 real examples of things you've actually sent — an email, a social post, a message to a client.

I want you to build "myvoice.md" so you can write in my voice going forward. I'm going to paste 2-3 examples of things I've actually written (an email, a social post, a message to a client — whatever's easiest). Analyze them for: sentence length and rhythm, vocabulary level, how formal or casual I am, how I open and close messages, words or phrases I use often, and things I never do (e.g. "I never use exclamation points" or "I never start with 'I hope this finds you well'"). Then write the final file as a style guide I can reuse.

Here are my writing samples:
[paste 2-3 real examples]

No samples handy? Just tell ChatGPT a sentence or two about your style — for example: "I'm casual but direct, I use short sentences, I never open with 'I hope this email finds you well.'" It'll be less precise but still useful.

How do I save the key facts to memory?

This uses ChatGPT's saved memory (Settings → Personalization → Memory):

Please remember the key facts from the aboutme.md, mybusiness.md, and myvoice.md we just built, so you have this context in future chats too.

Where should these files live?

1. Today: ChatGPT generates each file in the chat — copy the finished text or download it.
2. Next: create a ChatGPT Project (left sidebar → Projects → new project), upload all three files, and add key facts to the Project's custom instructions.
3. Ongoing: if your role, business, or voice changes, ask ChatGPT to update the file, then re-upload it to the Project.
