Open-source personal AI assistant Open Muse launches

On October 9, 2026, a developer announced Open Muse, a personal AI assistant released as fully open source under the MIT license, in a post on V2EX. According to the post, the assistant covers iPhone, Mac, and Android. It can set weekly reminders from a single sentence, store user preferences in a memory file (SOUL / MEMORY) that can be opened and edited directly, and keep tracking goals over time. On iPhone it reads Apple Health data on the spot to answer questions such as how a workout went, and it does not invent numbers it cannot read. It can also operate a Mac by viewing the screen, opening apps, clicking, and typing, but asks for confirmation before each step, with options to allow once, allow for the current conversation, or refuse; apps and folders the user has blocked remain off limits. The assistant queries Feishu tasks and creates documents through lark-cli, and can generate a PDF directly in a conversation and save it to a library. Tasks run in a cloud environment and continue after the app is closed, and a cloud browser can be taken over at any time. On the backend, Open Muse uses Managed Agents from Volcano Ark (火山方舟); users must supply their own Ark API Key and pay by usage, with model requests sent directly from the user's device to Ark rather than through the developer's servers. The official site is https://getopenmuse.com/zh/ , and the post says the Mac version is signed and notarized while the Android version can be installed directly. So far, this single announcement post is the only available source, with no other reports or later developments.
