Is that how you work 200%?
HPsquared•3h ago
I suppose the last 24 hours contains today and yesterday.
vavooom•2h ago
I applied this query with 4o and yes, quite a thorough historical recounting. Really weaves together all those "random" questions one asks an LLM into a surprisingly (and somewhat scary) encompassing of one's self.
holri•5h ago
I just asked Mistral.ai, using it without an account:

what do you know about me? 2:50pm

I don't know anything about you unless you share information with me. How can I assist you today? 2:50pm you do not know my IP and its location? 2:50pm

That's correct, I don't have access to your IP address or your location. If you need assistance with something specific, feel free to let me know!

BoiledCabbage•5h ago
Not to complain, but that test would be more interesting if you ran it with an account.
amelius•4h ago
Of course that doesn't prove much. Perhaps the information is only available to administrators.
noident•4h ago
You might as well have asked the pen on your desk how much it knows about you. Whether your personal data is in the current LLM context window or not has nothing to do with whether it was collected from you by Mistral.
wongarsu•4h ago
Rather than ask it if it knows anything about you, ask it where the nearest McDonalds is

Mistral seems honest in its assessment (as should be expected from a French company operating under GDPR). But e.g. ChatGPT will deny knowing your location, but still show a McDonalds that suggests it knows your IP geolocation

holri•1h ago
where is the nearest McDonald's? 18:51

I'm sorry, but I don't have the capability to access real-time location data to find the nearest McDonald's for you. However, you can easily find this information by using a maps application on your phone or computer.

> User’s account is 237 weeks old.

ChatGPT was released to the public on November 30, 2022.

Otherwise, this reads like an FBI file:

I created an account with OpenAI back in 2020 to try out GPT-3, which would explain that account age.

(I just confirmed that by searching my email for anything mentioning OpenAI in 2020 and found an invite to create an account in October 2020.)

jruohonen•4h ago
Same old but there has been surprisingly little attention paid to it in the present context.
nonelog•4h ago
The solution is to use www.duck.ai.

Full privacy, no data collection, no User profiling, no surveillance, no training with your data.

Plus, you can chose your preferred AI model: Claude, GPT, etc.

And it's even free of charge.

layer8•3h ago
Doesn’t offer access to the usual paid models, which is why it’s free of charge.
hardlianotion•3h ago
I still don't know what integrous means.
sydney6•2h ago
"Integrous" is a rarely used adjective meaning "having or characterized by integrity". It's derived from the Latin word "integer," meaning whole or complete, and the suffix "-ous" indicating fullness or possession. While technically correct, it's more common to use synonyms like "honest," "decent," or "virtuous" to convey the concept of integrity.

Now, take a guess where this comes from..

LLM's knowing things about us is genuinely useful - what's the alternative here?
Diti•1h ago
The alternative is that LLMs don’t know anything about us, of course. That’s what Kagi’s Assistants do.
GMoromisato•1h ago
I don’t care what chatGPT knows about me. But I do care what OpenAI knows about me and how it will use that knowledge.

The alternative is transparency and verification of who has that data.

holri•1h ago
That the LLM is in control of us.
BurningFrog•2h ago
FWIW, Grok answers this when asked "what do you know about me?" (I do have an account):

I don’t have any personal information about you, as I don’t have access to user data unless it’s explicitly shared in the conversation. If you’ve posted publicly on X, I could potentially look up your profile or posts to learn more, but I’d need your X handle to do that. Alternatively, if you want to share something about yourself—like your interests, location, or what you’re curious about—I can tailor my responses based on that. What would you like me to know or explore about you?

msgodel•1h ago
I know someone else who uses Grok and has the "learn from my responses" feature turned on, he claims it generates memories (like chatgpt did for a while) although he might just not understand how the dialog engine works.
EGreg•2h ago
When I speak to ChatGPT and other LLMs, I am mindful of the profile they build on me and what I ask about. And even how I ask it.

It is the same as I have been doing for 15 years on public social media.

nullc•2h ago
People's privacy expactations are miscalculated in a world with LLMs. Before LLMs there was little reason to care if you were leaving breadcrumbs, because no one with access was going to investigate them and draw conclusions from them.

The fact that the LLMs are prone to hallucinations and fanciful conclusion jumping probably make things worse, because the only way to be safe from it wrongfully concluding things about you is to just be invisible to it.

rcruzeiro•1h ago
Isn’t this just outputting the same information that you can find on my “administre memories” section of ChatGPT settings?
simonw•57m ago
No. That's the old memory feature, where you could view and delete individual memories.

This is the new memory feature where it automatically summarizes notes from your previous conversations.

I wrote more about the difference between the two here: https://simonwillison.net/2025/May/21/chatgpt-new-memory/#we...

marcusstorm•1h ago
This is like the prompts which ask the LLM to act as a spy / FBI agent, to expose what it knows about the user, right?
