Jarvis Orb

Not a tool. A presence.

It remembers your decisions. It tracks your world. It glows on your desktop, alive.

The Problem

Every session, your AI starts over. Your decisions, your preferences, your project context — gone. You explain yourself again. And again. And again.

"We decided to use SQLite." → Three days later, it suggests PostgreSQL.
"This PR was merged yesterday." → It doesn't know. It never remembers state.
"What was the architecture decision?" → Gone. The session ended.

The Solution

Jarvis Orb gives your AI a persistent brain and shows its thought process as a living orb on your desktop.

	Without Jarvis Orb	With Jarvis Orb
Context	Every session starts from zero	Carries over automatically
Decisions	Reversed decisions come back	Contradictions detected and filtered
State	"What's the status?" → guess	Exact state + transition history
Visibility	No idea what it's thinking	Every thought, live on your screen

Install

macOS (Apple Silicon) / Linux:

curl -fsSL https://raw.githubusercontent.com/whynowlab/jarvis-orb/main/install.sh | bash

Requires Apple Silicon (M1/M2/M3/M4). Use the terminal command above for the smoothest install experience.

Windows (PowerShell):

irm https://raw.githubusercontent.com/whynowlab/jarvis-orb/main/install.ps1 | iex

That's it. Brain starts. Orb floats. Claude Code connects.

Brain Lite

Watch it think.

#	Feature	Description
01	4-Tier Memory	Episodic, semantic, project, procedural — auto-classified and ranked by recency
02	Temporal Scoring	30-day half-life decay. Recent memories surface first. Old context fades naturally
03	Contradiction Detection	Conflicting memories flagged. Superseded decisions marked stale. Only truth surfaces
04	Entity Tracking	Projects, PRs, decisions tracked as objects with full state transition history
05	Relationship Storage	People → projects → decisions connected as a lightweight knowledge graph
06	FTS5 Search	Full-text search across all memories with observation filtering

MCP Tools

memory_save      Save a memory (auto-classified into 4 tiers)
memory_search    Search with temporal scoring + contradiction filtering
memory_verify    Mark memories as verified, superseded, or contradicted
entity_create    Track a project, person, decision, or tool
entity_update    Update entity state (records transition history)
entity_query     Query entities by type or name
entity_relate    Create relationships between entities

Works with Claude Code, Cursor, and any MCP-compatible tool.

Orb

Every thought, visible.

The orb is not decorative. It shows you what the brain is doing, in real time.

Brain Event	Orb Response
Memory saved	Particles absorb into orb
Contradiction detected	Red/orange pulse wave
Entity state changed	Cyan flash + scale pulse
Search executed	Violet color shift
Context compressed	Shrink, brighten, expand
Team dispatched	Orb splits into sub-orbs

3MB desktop app. Always-on-top. Draggable. Click to see logs.

In Practice

Monday morning standup — "What did we work on last week?" Brain searches episodic memories with temporal scoring. Returns a ranked summary. No digging through chat history.

Mid-project contradiction — "We should use Redis for caching." Brain detects this contradicts a previous decision. Flags the conflict. The orb pulses red. You see it happening.

New session, no context loss — "Continue where we left off." Brain loads project state, recent decisions, and your preferences. No re-explaining.

Architecture

     ↕  MCP (stdio)
Brain Lite  —  Python · aiosqlite · FTS5 · ~/.jarvis-orb/brain.db
     ↕  WebSocket
Orb  —  Tauri · Three.js · WebGL · 3MB · Always-on-top


3MB	App size. Not 150MB.
7	MCP tools. Memory, entities, search.
0	Cloud dependencies. Everything local.

Origin

Jarvis Orb was extracted from a working AI control plane — Jarvis — running 19 modules, a knowledge graph with 100+ entities, 500+ memories, and 22 agent teams. This is the lightweight, open-source version of that brain.

"I built a personal AI operating system. After months of using it, I realized the core — the brain and the visualization — should be available to everyone."

Roadmap

Orb Customization — Custom orb skins, color themes, animation profiles
Brain Pro — Advanced memory with full knowledge graph, multi-model routing, autonomous reasoning loop
Auto-update — Seamless in-app updates
Plugin System — Extend Brain with custom MCP tools
