Copilot
Copilot that knows your business. In every chat.
With Keepstone you put the core of your business into Copilot. Who you are, what you offer, who for and how you write. Copilot 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.

I use Copilot to prepare business texts and communication for clients. Without context the results were often too general. Now Copilot knows my services, target audience and writing style better and I have a more useful starting point for my texts.
