I taught ChatGPT, Claude, and Gemini the same lie

When AI tools were still in their honeymoon phase, they weren't any good at personalization. All you could really do was start a fresh chat, dump in whatever context the model needed, and you would get an answer shaped entirely by that one conversation.

AI labs have directed a lot of their efforts toward improving personalization, and memory is the centerpiece of that push. Claude keeps a memory summary too, but it sorts what it stores into labeled categories like Profile, Education, Food, and Reading.

What Happened

These are all memories Claude generates from your chats, and you can open, edit, or delete each one individually. It also has a separate feature that lets it search back through your past conversations, but that's distinct from the memory.

• That works when it comes from a single conversation you can find, but it leaves you with very little the moment things get more tangled, or you simply want to see what Gemini has.

• Since there's no summary to open, no list of entries, and nothing you can edit directly, the only option you have is to delete the underlying chat and hope you've caught every place the.

• However, though it worked well in this experiment, I think it has the weakest memory and personalization options out of the bunch (despite the launch of Personal Intelligence).

Key Details

It doesn't give you a memory summary to read at all. Under its Personal Intelligence settings, there's a Memory toggle that "learns from your past chats," a Connected Apps section, and a space to write your own standing instructions, but nowhere to.

• Correcting it in conversation worked better than it did on the other two, so it definitely won this round fair and square.

• There's no memory summary to inspect, so you're left inferring what it knows from how it answers.

• The whole point was to see whether these tools would actually forget when you correct them the way most people do rather than by digging into settings.

Why It Matters

What it knows is inferred from your past conversations and Google activity. The idea here was to tell each assistant something false about myself, then see how hard it was to take back.

• While I had the option to simply make the edit in the memory summary for both Claude and ChatGPT, I didn't want to take the manual route.

• It was the only tool that reverted to the original lie, and it took repeated corrections across multiple chats before the change actually reflected in the memory summary.
