Show HN: Kuma Voice – OSS Apple Watch voice assistant, no iPhone needed

Kuma Voice, an open-source voice assistant built for Apple Watch, launched on August 26, 2026, with a focus on standalone operation — no iPhone required. The project was posted to Hacker News as a Show HN by its author, itsperini, and the source code is publicly available on GitHub.

The core premise, per the HN submission, is that the assistant runs directly on Apple Watch hardware without depending on a connected iPhone for processing or relay. This targets users who want wrist-based voice interaction in contexts where carrying a phone is impractical or unwanted.

Beyond the name, the open-source nature of the project, and its iPhone-independent architecture, the GitHub listing provides no additional detail in the submitted metadata about underlying models, specific watchOS version requirements, or what voice commands and integrations the assistant supports. No company, team size, funding, or founding date is mentioned in the source material.

Apple Watch has supported a degree of standalone cellular and app functionality since watchOS 4, but Siri on the device still routes requests through Apple's servers and, in many workflows, through a paired iPhone. A fully self-contained, open-source alternative addresses a gap for developers and privacy-conscious users who want more control over that pipeline, though the practical scope of Kuma Voice's capabilities is not described in the available sources.

At the time of the HN post, the submission had three points and no comments, per Hacker News. No additional corroborating sources covered the launch. Further details on roadmap, supported features, and contributor guidelines would need to be drawn directly from the project repository.
