A full AI assistant — writing, images, web search, memory, file uploads — where every conversation is end-to-end encrypted on your device, so the company says it cannot read your chats, train on them, hand them to partners, or produce anything but scrambled text in response to a subpoena. Built by Moxie Marlinspike, the cryptographer who created Signal. Free to start with no credit card; the encryption and private inference designs are written up publicly and the code is open source so the claims can be checked.
Why I recommend it: This is the one to reach for when you are about to type something into an AI that you would not want read back to you — money trouble, health, a manager, a visa problem. Two honest things. It is free to start, which is not the same as free forever, so read the plan page before you rely on it. And encryption protects the message, not your judgment: anything you paste in that belongs to an employer or a client is still their information, whoever can or cannot read it.
A practical guide to using AI chatbots without handing over everything you tell them, built on interviews with Johns Hopkins cryptographer Matt Green and Signal creator Moxie Marlinspike. It explains why a chatbot is a better honeypot for your secrets than text messages ever were — most are set by default to store what you say, with few limits on training, sharing, or handing it to a court — and walks through the options that actually reduce the exposure.
Why I recommend it: The clearest plain-language explanation of why this matters, and the best thing to read before you pick any of the tools above. Marlinspike's line is the useful one: the private things people used to text are now the things they tell an AI, and the protections have not caught up. One flag — WIRED meters free articles, so if you hit a sign-in wall, tell me and I will note it on this entry.
