Description

Hi HN — I built Hearth for my family: https://ourhearth.aiHearth is a shared workspace for a household. We use it for plans, notes, schedules, people, and recurring family rituals, with an AI agent that can work across that context. Kind of like a shared Obsidian with an agent.The cool part is that the agent can also build apps on top of the family's notes and run them inside the same workspace. We have a calendar and a travel app, for instance, and all the apps I use to manage my company's operations are in another Hearth.Hearth is built on Playground, a library we're developing for building collaborative AI coding harnesses. The common primitives are synchronized files, agents, people, app code sandboxing, and a policy layer. Hearth is the family-scale example; we're building Bear for construction projects using the same library.Hearth is beta software! We designed it with isolation and least-privilege in mind, but I recommend that you don't put anything too sensitive in there until the source is out and stable (we're making Hearth open source soon).If this sounds like something you family could use, check it out and let me know what you think!More background: [Hearth: Build your own assistant](https://bear.build/posts/hearth-build-your-own-assistant/)
