Meet HachiAnswers only to you

A personal AI that runs on your machine. Your memory, your credentials, your conversations — they never leave.

The Problem

Your AI is a rental apartment

The landlord reads your mail, raises the rent whenever they want, and kicks you out if you miss a payment.

🧠

Amnesia

No long-term memory. Every session starts from zero.

🔒

Their Servers

Your conversations become training data for the next model.

🚫

No Access

No filesystem. No apps. Needs internet to form a sentence.

Gated

3 months to publish a plugin. They call it "ecosystem."

The Difference

What Hachi gives you

  • Memory graph — 7 node types, emotional charge, fidelity decay
  • Full computer use — screen, keyboard, mouse, any app
  • Runs on your Mac — thinks locally with Ollama
  • Zero telemetry — your data has never touched another disk
  • 71 skills — new tool in 30 seconds, no gatekeeper
  • Free forever — download it, use it, it's yours

Architecture

Three processes. Your secrets shouldn't be visible to the AI that's reading them.

🧠

Assistant

LLM orchestration, tools, memory graph, personality. Never sees a raw credential.

🛡

Gateway

TLS, JWT auth, webhook routing. Can't read conversations.

🔐

CES

Encrypted vault (AES-256-GCM). Different process, different address space.

Security

Your AI can see your screen.
It should never see your passwords.

  • WASM sandbox — zero capabilities by default
  • CredentialInjector at the host boundary
  • 66 patterns scanning every output
  • 14 guard tests in CI on every commit
  • Fail-closed — if sandbox fails, tool doesn't run
$ hachi tool run api-fetch
→ WASM sandbox: caps = {}
→ CredentialInjector intercepts
→ 200 OK (tool never saw the key)

$ grep -r "ghp_" tool-output/
→ 0 matches. As designed.
Memory

Hachi doesn't wait for you to ask. It already knows what you need.

  • SOUL.md — predicts your personality and style before you speak
  • Memory graph — surfaces relevant context from weeks ago, unprompted
  • NOW.md — knows your current project in real time
  • Heartbeat — reaches out proactively when something needs attention
  • Local embeddings — ONNX dense + BM25 sparse, ranked by RRF. Always local
Self-Improving

It doesn't just create tools.
It rewrites its own behavior.

Hachi writes TypeScript, sandboxes it, and persists new skills at runtime. But it goes further — it reflects on mistakes and evolves its behavioral rules.

// Sandbox → evaluate → persist

await evaluate_typescript_code({
  code: `export default async (i) =>
    (await fetch(i.url)).json()`
});

await scaffold_managed_skill({
  id: "api-fetch"
});

// No redeployment. Next session: ready.
Computer Use

Siri can set a timer.
Hachi can fill out your tax return.

  • Dual perception — AX tree + screenshot in parallel
  • CGEvent injection — native keyboard and mouse
  • Adaptive wait — AX polling until UI settles
  • Consent-first — every action, every time
▸ Capturing AX tree + screenshot…
▸ 142 UI elements indexed
▸ Requesting confirmation…
▸ Approved. 3 actions.

▸ 1/3: click "Safari" · 2/3: type URL · 3/3: fill form
▸ Complete. UI settled.

Hard Questions

The questions nobody else will answer. We will.

💭 "Isn't this just another AutoGPT?"
AutoGPT ran out of context in 4 turns. Hachi has 212 migrations, 14 guard tests in CI, and 871 test files. Infrastructure built over a year of daily iteration.
🤔 "If it's free, you're the product."
No. Hachi is free for personal use — you own the data and the deployment. Companies pay for managed deployment and SLA.
🧠 "Doesn't it need a 100B model?"
No. Intelligence is routing, not scale. Fast models for simple queries. Powerful models for reasoning. The right brain for the right job.
The Clone Lifecycle

Day 1, it's a capable stranger. Day 90, it's yours.

Day 1

71 skills, 8 channels, full computer use — but knows nothing about you.

Day 7

Knows your projects, preferred tools, communication style. SOUL.md has its first contours.

Day 30

Handles routine requests without instruction. Reaches out proactively. Has created custom skills.

Day 90

Thinks like you, talks like you. Evolved behavioral patterns that match your style. Not programmed — learned.
