You can now lock chats in ChatGPT

“A long time ago in a galaxy far, far away” was not written by George Lucas. It was written by Brian De Palma after he sat through a rough cut of Star Wars in 1977 and had a full screaming match with Lucas at dinner because he couldn’t follow the story.

De Palma rewrote the opening crawl that night with a film critic named Jay Cocks. The most iconic opening in cinema history was born from two directors yelling at each other over a meal. George Lucas built a $10 billion franchise on it and Brian De Palma went back to making Scarface.

OPENAI

The family iPad has never been safer

OpenAI has introduced Locked Chats, a new ChatGPT feature that lets users protect private conversations with a four-digit PIN, Face ID or Touch ID on supported devices.

Unlike Temporary Chats, which disappear from your chat history, Locked Chats can be reopened whenever you need them.

Here's how it works:

Locked conversations move into a separate section and won't appear in your regular chat history, pinned chats or search results.
When Memory is enabled, Locked Chats have their own memory, so new information shared there won't carry over into regular conversations.
Locking a chat doesn't add end-to-end encryption, change how OpenAI stores your data or affect your existing privacy settings. Resetting your PIN also permanently deletes content protected by the old PIN.

The password is NoneOfYourBusiness

The feature is designed for conversations you'd rather keep hidden when sharing your device, whether that's personal information or plans for a surprise.

The feature is rolling out across most ChatGPT plans, including Free, Plus and Pro, although it isn't available to everyone yet.

Just like incognito mode it will only be used for buying presents in secret, right? -MV

Would you lock your ChatGPT conversations?

No, my dignity left years ago.

CHATBOT

The curious case of the $20M chatbot

AI is getting involved in criminal investigations, and investors are putting millions behind it.

San Francisco startup Longeye has raised $20 million in new funding, bringing its total to $25 million.

Its AI helps US police and legal teams analyse huge amounts of digital evidence, including surveillance footage, phone records and witness statements.

The idea came after co-founder Guillaume Delépine experienced a burglary and discovered that local police were juggling around 300 open cases.

He wanted to help investigators spend less time sorting through records and more time solving crimes.

Around 50 US justice agencies already use Longeye, including 30 public defenders' offices.

However, experts warn that AI errors, bias and the increased use of surveillance data could have serious consequences for criminal investigations.

Here's what else to know:

Investigators can ask a chatbot to search evidence, build timelines and spot conflicting statements, with findings linked to original records.
Experts warn that making surveillance data easier to analyse could raise civil liberties concerns, especially if AI makes mistakes.
Longeye says investigators remain responsible for decisions and plans to invest in stronger safeguards, training and oversight.

Elementary, my dear algorithm

AI could help speed up investigations, but experts say reliable safeguards and human judgement will be crucial when people's freedom is at stake.
