Signal's founder just brought encrypted AI to Meta's 3 billion users
Moxie Marlinspike's encrypted AI chatbot Confer is integrating into Meta AI — bringing Signal-level privacy to the world's largest social platform.
The person who made WhatsApp's encryption possible just struck a deal to do the same thing for AI. Moxie Marlinspike, the cryptographer who co-founded Signal and wrote the encryption protocol used by billions of people, announced that his encrypted AI chatbot Confer is bringing its privacy technology to Meta AI.
The problem: your AI chats reveal how you think
Every time you ask ChatGPT for medical advice, career guidance, or relationship help, that conversation is stored on a server. Marlinspike's warning is stark: AI chat logs reveal how you think — and could become "a profoundly more powerful form of advertising," like "a third party paying your therapist to convince you of something."
Unlike regular messaging, AI conversations often contain your deepest questions, insecurities, and decision-making processes. That data is a goldmine for anyone who wants to influence you.
How Confer makes AI truly private
Confer looks and feels like ChatGPT — you type a question, you get an answer. But the technology underneath is radically different:
- Your message is encrypted on your device using WebAuthn passkeys (the same technology behind passwordless login)
- The encrypted message travels to Confer's servers
- It's decrypted only inside a Trusted Execution Environment (a locked hardware vault that even Confer's own engineers can't peek into)
- The AI generates a response inside that vault
- The response is encrypted again and sent back to you
Result: nobody can read your conversations — not Confer, not hackers, not governments. Not even Moxie himself.
Now it's coming to Meta — and 3 billion users
In a blog post on March 18, Marlinspike announced that Confer's encryption technology will be integrated into Meta AI — the AI assistant built into WhatsApp, Instagram, Facebook, and Messenger.
He framed it as history repeating itself. A decade ago, Marlinspike's Signal Protocol was integrated into WhatsApp, bringing end-to-end encryption (the technology that means only you and the person you're messaging can read your conversation) to billions of people overnight. Now he's doing the same for AI conversations.
Confer will continue operating as an independent company while its technology powers Meta's AI privacy layer.
What's still unclear
The announcement is light on specifics. Key questions remain:
- Which Meta products first? — Meta AI chat is confirmed, but what about AI features in Instagram, WhatsApp, or the new smart glasses?
- Can Meta still see any data? — The encryption architecture should prevent it, but independent audits haven't been announced yet
- Timeline? — No launch date given
Try Confer right now
You don't have to wait for the Meta integration. Confer is available today as a standalone AI chatbot. The free tier includes 25 messages per day and up to 5 active chats. The paid plan ($35/month) unlocks unlimited messages and access to more powerful AI models.
Why this matters beyond the tech
If this integration works as promised, it would be the first time a major tech platform offered AI that genuinely cannot spy on you. In a world where every AI company is racing to collect more data, Meta partnering with the person synonymous with digital privacy is either a genuine commitment to user protection — or the most effective privacy marketing move in tech history.
Either way, billions of people may soon get access to AI that keeps their secrets.
