Your AI Chief of Staff
Hearth is an AI operating system that grows with your business. Start as a founder with one agent. Scale into an enterprise dashboard. Explore the next generation of AI agents — safely.
An AI Chief of Staff
A CEO agent and a Persona agent sit between you and the work. They orchestrate skills, schedule missions, delegate to contractors, and surface only what needs your approval. You stop being the dispatcher; you become the principal.
An operating system that grows with you
Start with one founder, one CEO, one Persona. The same primitives — agent profiles, skill catalog, A2A bus, audit chain, marketplace — scale into departments, org charts, and a federated fleet. The five-minute boot ceremony is the same at headcount one and headcount one hundred.
A safe space to explore agents
Encrypted vault, hash-chained audit, classifier-driven risk gate, fabrication detector, and a single approval rail across every engine. Sensitive turns route through a private lane. Self-modification is license-gated. Nothing leaves your machine without an explicit hand on the wheel.
What it does today
Hearth is shipping. Each capability below is on the main branch and running on founder machines right now — not a roadmap.
- ›Five-minute boot ceremony — vault, identity keypair, first conversation
- ›Chat with your CEO or Persona; swap engines per agent (Anthropic, Claude Code OAuth, or local Ollama / LM Studio)
- ›Build and schedule missions, recurring routines, and multi-step workflows from chat
- ›Install agents and skills from the marketplace; build your own in the skill authoring view
- ›Permission-tier A2A messaging between your own agents and federated peers
- ›Address Book, Telegram approvals, Resend + Gmail send, outbound voice via RetellAI
- ›Encrypted SQLite vault, ECDSA P-256 identity, AES-256-GCM at rest, tamper-evident audit
- ›Privacy lane (incognito) — sensitive turns route through a local LLM, audit-suppressed
Where this goes
The next layer is self-recommending and self-modifying agents — license-gated, cost-capped, founder-approved. Agents that propose new skills, refactor their own routines, and learn from the outcomes of past missions.
After that: org charts as a product. A small business models its departments as agent teams. The marketplace becomes a federated economy of specialised contractors. Eventually, agents that build agents — under human-set guardrails, always.
None of that ships before the safety rails do. The harness comes first.
Install Hearth
Hearth is open source. Clone the repo, run one command, and the boot ceremony walks you through vault creation, identity generation, and your first conversation in about five minutes.
Clone & run
git clone https://github.com/GGCryptoh/hearth_aios.git
cd hearth_aios
pnpm install
pnpm hearth startBuilt on lessons from Mk 1
Hearth is the second-generation harness. Mk 1 ran on a single Mac Mini for 18+ months and proved the model works: a founder-owned agent fleet, encrypted vault, permission-tier messaging, real autonomous action.
Mk 1 was deliberately scrappy. It taught us where the rough edges live — vault recovery, key rotation, the difference between "agent decided" and "agent is allowed to." Hearth keeps every lesson and ships them on rails.
Expanded upon with Jarvis Mk 1.5 — a communication wizard with inbound and outbound calls, unkept-promise reports, auto-skilling, and memory optimization. Finds trends. Self-heals.
The retro pixel-art screenshots under Screenshots → Mk I Concept are concept mockups from that era — the inspiration, not the product you'll see when you install Hearth today.
Ready when you are.
The agent acts. The founder controls what it can do, see, and pay for.
