Signal Creator Moxie Marlinspike Wants to Do for AI What He Did for Messaging

Moxie Marlinspike, the creator of Signal, has launched Confer, an open‑source AI assistant that encrypts user prompts and LLM responses end‑to‑end. The system uses passkeys, trusted execution environments, and remote attestation to keep data unreadable to operators, hackers, or law‑enforcement. Confer’s code is publicly auditable, with signed releases and a transparency log, mirroring Signal’s privacy‑first design. Competing privacy‑focused LLMs such as Proton’s Lumo and Venice exist, but major providers have yet to adopt true end‑to‑end encryption.
