Mistral Puck
Concept and use cases
The Mistral Puck is a self-contained AI voice assistant with no screen. A puck you keep in your pocket and activate with a finger: press, speak, release. Every interaction goes through voice — there's nothing to look at, nothing to scroll.
What sets it apart from a smart speaker is access. The on-board agent works inside your mobile digital environment — messaging, calendar, reminders, navigation — reading and writing alike. It doesn't just answer questions: it looks at what concerns you and acts on it. It's the logic of OpenClaw carried over to the phone — an agent with its hands on your tools, rather than a chatbot cut off from your data.
The device is stand-alone: it isn't a remote for a phone, it is one. The 3D-printed case is built around a Galaxy S20 Ultra 5G motherboard, which gives it the connectivity, compute and sensors of a high-end smartphone from the outset — without the screen.

Progress
The Mistral Puck works physically: the case is printed, the electronics fit inside and run. Most of the work has shifted to firmware, where the agent gains capability with every iteration — more tools within reach, better context, sharper answers.
Planned features
The goal is a purely spoken companion. In the morning, the Puck tells me what matters: the messages worth a reply, the day's tasks, the appointments coming up — with enough context that its suggestion is genuinely useful, not just a readout of notifications.
That requires an agent that can sort and prioritise rather than recite everything. That's the real work — less a hardware problem than a question of judgement.
