we talk a lot at home. random conversations over dinner, quick decisions while rushing out, plans made in passing, jokes that land perfectly in the moment and then disappear forever.
most of it just evaporates. we forget what we decided, we lose track of who said they'd handle what, we can't remember that funny thing the kid said last week. our homes are full of words but none of it sticks unless we actively write it down, and lol who does that at home.
voice assistants today are transactional. you ask them to set a timer, play music, check the weather. they don't remember your conversations. they don't understand context beyond a single command. they're tools, not memory.
hearth is different.
it’s a tiny device in every room that listens and turns family talk into something you can speak back to. you talk, like just as usual and the house turns the moments into searchable notes, short stories, reminders, or a voice you can ask about later. it's not a recorder for the sake of recording audio. it's a living, speakable memory for the family to use.
and how it feels is, you walk in, say something, and later you can ask the house "what did we decide about naveen’s birthday" and it answers from what you spoke a week ago. it makes short summaries after dinner. it highlights tasks. it captures the joke someone told and plays it back when you ask. it can create a bedtime story from today's goofy moments, surface the grocery item you mentioned yesterday, or remind you of the exact phrase someone used so you don't forget.
**simple guardrails:**
keep control in the family's hands. choose which rooms remember, who can ask, and what gets kept.
local processing for quick stuff, cloud only when you opt in for deep search or long term memory. the point is a useful, speakable household brain that helps families remember, decide, and laugh together.
**and to build this, these are what we'd probably need:**
hardware:
small devices for each room, unobtrusive, blend into the space.
good microphones that pick up natural conversation without being invasive.
local processing chip for real time transcription and basic memory.
minimal power draw, always on but not draining.
software:
speech to text that handles multiple voices, accents, interruptions, the mess of real family talk.
context understanding, knows the difference between a task, a joke, a decision, a random comment.
memory structuring, organizes conversations into retrievable moments without you having to tag or label anything.
query processing, understands natural questions and retrieves relevant memories.
summarization, can compress a long dinner conversation into key points.
task extraction, pulls out things that need doing without you explicitly saying "remind me to..."
voice synthesis for playback, so the house can tell you what happened in its own voice or play back actual recordings when needed.
the app (mobile/web):
dashboard of recent memories and active tasks.
controls for which rooms are active, privacy toggles for sensitive spaces like bedrooms.
permissions management, who in the family can query what.
memory browsing, timeline view of captured moments.
export options, save specific memories as audio clips or text.
storage settings, how long to keep things, what to delete automatically.
**the ideal things it should have:**
instant recognition of who's speaking, adapts responses based on family member.
works entirely offline for core functions, cloud is optional for advanced features.
strict privacy architecture, nothing leaves the home unless you explicitly choose.
handles overlapping conversations, doesn't get confused when everyone talks at once.
learns your family's patterns, gets better at knowing what matters over time.
kid safe modes, filters or limits what children can query.
seamless, feels like talking to your house, not operating a device.
the tech for transcription, summarization, and voice interaction exists.
the models are getting good enough to handle messy, real world conversation. the challenge is making it feel natural, private, locally computable and useful without being creepy.
and as voice interfaces become more embedded in our lives, the home itself becoming a conversational memory layer makes sense. not recording everything for surveillance. just remembering the things families want to remember.

feel free to hit me up. i’d be happy to talk about this more and possibilities.
