Context: why AI doesn't remember yesterday

AI has no memory like a human. Everything it “knows” about your work is exactly what it has in front of it in the conversation right now. That's called the context. A new conversation means a clean desk: what you discussed yesterday doesn't exist today.

Imagine a brilliant temp worker who shows up every day as if it were their first day. They know the craft perfectly, but they know nothing about your company, project or habits until you tell them or hand them something to read. That's exactly how AI works. It isn't stupid. It just arrived.

And not everything fits on the desk

Context has a limited size. When a conversation gets too long, the oldest parts start dropping out or losing weight. AI “forgets” what was at the beginning, mixes things up, contradicts itself. Typical signs: it asks about things you already said, or breaks a rule you agreed on long ago.

There's a subtler version too: the more clutter in the conversation, the worse the dice rolls from the first tip. An overstuffed context quietly degrades quality even before anything is truly “forgotten”.

Three habits that solve it

1. Important things go in a document, not in the chat. Write the brief, the rules and the state of the work into a file you can attach to AI any time. A long conversation gets lost, but a document survives, and a fresh conversation is up to speed in a second. On bigger projects, keep one notes file that AI itself updates as it goes. “Write down the current state” at the end of a session works wonders.

2. Don't be afraid to start over. When a conversation gets tangled, a new one with a short summary (“we're working on X, Y is done, Z is next”) is usually faster than rescuing the old one. A clean desk isn't a loss, it's a quality reset.

3. One topic, one conversation. Don't mix invoices, marketing and holiday planning in a single thread. Every topic deserves its own desk. AI then doesn't have to wade through the clutter of the others.

Remember

• AI only knows what's in the current conversation. Every day is “day one”.
• Important things belong in documents and notes you can attach, not in a long chat.
• Don't rescue a tangled conversation. Start a new one with a brief state summary.
