On Monday a client asks about the start date. Quartio already knows the agreements from the email, the meeting and WhatsApp, knows which one holds, prepares a reply for your approval and comes back to the matter on Friday if the client does not reply. ChatGPT helps you write the reply once you give it the information.
ChatGPT’s memory covers what you tell it and your conversations with it. Quartio’s memory is the whole company’s agreements: who promised what, when and where, what holds and what was replaced, with a link to the source.
You talk to Quartio on WhatsApp, in the browser, or in Claude and Codex through MCP. You don’t need another window to ask about a matter.
It doesn’t have to. ChatGPT stays for writing and ideas. Quartio takes over what ChatGPT doesn’t do for you: remembering the company’s agreements and keeping track of matters.
Yes. ChatGPT for writing and ideas, Quartio for the company’s matters that someone has to remember and keep track of.
Quartio is a monthly subscription for the company. We give the amount at the first meeting, once we know how many people and tools it covers, and put it in the order before the start. The first meeting costs nothing.
At the first meeting we pick one matter and connect only the sources it needs, together. You check the answers on your own matters straight away, and the scope grows once you see the benefit.
