Signal Creator Develops AI Assistant Focused on Complete Privacy of Conversations

Moxie Marlinspike, a software engineer best known for creating the popular Signal messenger with strong emphasis on user privacy and security, is now preparing to launch Confer — an open‑source AI assistant designed to ensure that user data remains inaccessible to platform operators, hackers, law enforcement, or any third party other than account owners.

Developed as open‑source software, Confer’s language models and backend components can be cryptographically verified by cybersecurity experts.

User data and conversations, as well as model responses, are encrypted within a trusted execution environment (TEE), preventing even server administrators from viewing or altering them.

Confer stores conversations in encrypted form using keys located on user devices.

Cybersecurity specialists note: “AI models are inherently data collectors. They rely on gathering large volumes of information for training, improvement, operations, and personalization. Most often this data is collected without clear informed consent and transferred to private companies.”

Moxie’s approach is therefore notable. One of Confer’s core encryption components is the use of passkeys — a standard that generates a unique 32‑byte key pair for each service a user connects to. The public key is sent to the server, while the private key remains only on the user’s device.

The private key allows the device to connect to Confer and encrypt all incoming and outgoing data, making it virtually impossible to compromise.

Beyond strong privacy, the developer promises simplicity in architecture and design.

Thanks to passkeys, all previous chats can be decrypted in just two steps, enabling quick return to dialogue with the chatbot, and re‑encrypted just as fast upon exit.

The launch of Confer is expected to encourage other AI developers to prioritize user privacy.
