About antimattr
antimattr is building the hardware interface for human–agent interaction: an AI wearable system made up of a smart ring and voice-isolating earbuds. Voice is the fastest way to instruct an AI agent, but most people won’t use it in public because it’s noisy and unreliable. We think voice AI adoption is held back by hardware, not by model quality. The earbuds use our proprietary voice isolation to capture your voice clearly anywhere, whether that’s a loud pub, a factory floor or a busy street. That means clear calls and dictation/transcription you can trust. The ring is a discreet way to control your agents. Tap to capture a thought, trigger a workflow, or record/summarise a conversation into a searchable personal memory.
