KeepstoneYour second brain for your own AI

ChatGPT

ChatGPT that knows your business. In every chat.

With Keepstone you put the core of your business into ChatGPT. Who you are, what you offer, who for and how you write. ChatGPT uses it in every chat. You never have to explain yourself again.

You get your second brain for Claude, ChatGPT, Gemini and Copilot. You choose which to install.

What's in it for you

  • An email to a client that sounds like you.
  • A LinkedIn post that fits your services and your audience.
  • A client meeting you prepare without first explaining who you are.

What you get for ChatGPT

  • The core of your second brain, ready to paste into your personal settings.
  • A copy button per field. You don't have to count or shorten anything.
  • Ground rules for ChatGPT. Ask instead of guessing.
  • Your full second brain as separate files. You hand them over when a question calls for it, for example your rates when you ask for a quote.
  • And your second brain for Claude, Gemini and Copilot. You choose which AI to put it in, one or all four.

How to set it up in ChatGPT

Four steps, once.

  1. Open ChatGPT, click your name at the bottom left and choose Personalization. Under Custom instructions, click ChatGPT.
  2. Copy text 1 from your download page and paste it into the field More about you.
  3. Copy text 2 and paste it into the large field at the top of the page.
  4. Click Save and open a new chat.

What to expect, and what not to

ChatGPT follows your settings, but it is still an AI. Anything that isn't in your settings, such as your full rates, you give yourself in the conversation. Always check important texts such as quotes yourself.

I use ChatGPT for emails, client questions and texts for my website. I used to have to explain how I approach my clients and which services I offer. Now my own business profile is the starting point and I have less to adjust afterwards.
