Personal AI memory and company memory are different jobs
The memory features in ChatGPT, Claude and Copilot remember a person. A firm needs its AI to remember the firm. Here is the difference in practice.

Two account managers at the same firm ask their AI assistant the same question on the same afternoon: "What are our payment terms for new corporate clients?"
One gets "30 days from invoice." The other gets "50% upfront, balance on delivery." Both answers are delivered with full confidence. Both came from the assistant's memory.
The first account manager mentioned 30-day terms in a chat back in February, when the firm still offered them. The second told the assistant about the upfront deposit rule in May, after the finance lead changed it. Each assistant remembered its own user faithfully. Neither knew what the company had decided.
This is the gap in the memory features most people now have access to, and it is worth understanding before you rely on them.
What vendor memory is built to do
During 2025 the big assistants all invested in memory. Microsoft gave Copilot its own memory so it could personalise answers to the individual. Anthropic brought memory to Claude, including Team and Enterprise plans from September 2025, with memory separated by project. ChatGPT expanded its memory to draw on past conversations.
These features are designed around a person. They remember your preferences, your writing style, the project you mentioned last week, the fact that you prefer bullet points. For an individual, that is genuinely useful. You stop repeating yourself.
Where a firm needs something else
A company needs its AI to hold things that are true for everyone, decided by someone with the authority to decide them. Put the two side by side and the differences are practical, not philosophical.
Whose facts are they? Personal memory holds what one user said. Company memory holds what the firm has agreed: the current terms, the current price list, the current approval rules. When those conflict, the firm's version has to win, and personal memory has no way to know there is a firm's version.
Who can see and correct it? With most vendor memory, you can view and delete entries for your own account. A manager cannot open the team's memories and check whether the payment terms everyone's assistant believes are the right ones. A company memory has to be readable and editable by the people responsible for it.
Is anything marked as verified? Personal memory treats a passing remark the same as a decision. Company memory needs to know the difference between "someone mentioned this once" and "the finance lead confirmed this on 12 May".
What happens when someone leaves? When an employee leaves, whatever their assistant learned about your business leaves with their account. Company memory stays with the company.
Which tools can read it? Vendor memory lives inside that vendor's product. If half your team uses one assistant and half use another, there are two separate memories, and neither can see the other.
What we do
At Provecta, the company's working memory is a set of written files the company owns. Every AI working session reads the same context and the same standards at the start, whichever person is running it. Decisions go into the shared record with the date and reason, so when a rule changes, it changes for every session at once.
We still use personal preferences inside the tools. Nobody needs a company policy on whether they like bullet points.
What company memory costs
It is not free, and the cost is mostly time. Someone has to decide what the firm's answer is, write it down and keep it current. Personal memory fills itself in as you chat. Company memory gets filled in by people making decisions and recording them, which is slower and requires an owner.
It also does not settle disagreements for you. If the finance lead and the sales director have different views on payment terms, writing one of them down is a decision, and someone has to make it.
Try this with three people
Ask three people on your team to open their AI assistant's memory or saved instructions, if it has them, and read what is stored there about the business. Not about them personally. About prices, terms, clients, policies.
Compare the three. Anything that differs between them, or that is out of date, is a fact your firm should be holding in one shared place instead of three private ones.
