Show HN: Hearth – a shared family workspace where an agent can build apps
Hi HN — I built Hearth for my family: https://ourhearth.ai
Hearth 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!

This looks cool! wondering how this can connect to the different kinds of devices in my home? and what does it look like interfacing with with Hearth for different member's of the family?
We don't have a ton of IoT providers built in right now but you _can_ hook up anything with an API by configuring a proxy with an API token. That will let the agent access the device without having access to the token.
Then you can ask the agent to write an app for you! It can just give itself tools to do stuff with the devices or can make a full UI.
What it looks like for different members of the family: everybody has access to the same stuff. Everything is syncced between all devices and any integrations you add are available to the other people in the household. Hopefully you all like each other.
I pushed my Home Assistant app here, you can look at it or ask your Hearth agent to copy it into your Hearth https://github.com/bearbuild/hearth-apps/tree/main/home-assi...
I just have the UI working with speakers, but the tool it has can do a ton, so you can ask Agent Heath to control all sorts of home assistant stuff.
Also, if you want the UI to be different, just ask :)
