Ultra-Lightweight Go Agent

An autonomous engine
for your desktop.

Written entirely in Go. OsirisBrainNano delivers instant startup with exactly 280+ native OS, browser, and workspace tools. It dynamically auto-creates new skills, features a Triple-Layer SQLite Memory, and runs Metal/CUDA optimized local inference via a bespoke llama.cpp engine.

macOS, Windows & Linux · Designed for Metal/CUDA Local Inference, Anthropic, DeepSeek, Gemini & OpenAI

Autonomous Evolution

Limitless Capabilities.
It builds its own tools.

OsirisBrain isn't just a static program. When faced with a problem it lacks a tool for, its deep neural architecture dynamically analyzes, codes, tests, and deploys new specialized skills in real-time. It evolves autonomously to solve your exact challenges.

1. Analyze

Identifies missing capabilities required for the task.

2. Code

Synthesizes new tools and logic autonomously.

3. Test

Validates the new skill in an isolated sandbox.

4. Deploy

Integrates the tool into its permanent memory.

Auto-Evolution Engine Active

Capabilities

Everything you need. Nothing you don't.

Pure Go Architecture

Written completely in Go for instant start times. Zero Python GIL overhead. Delivers goroutine-level performance and isolated subagents on Mac, Windows, and Linux.

Local & Cloud Models

Total freedom. Run large-scale architectures locally via a highly-optimized bespoke llama.cpp engine natively, or use external APIs like Anthropic, OpenAI, Gemini, and DeepSeek via a unified interface.

Self-Healing Doctor

Advanced diagnostic system. Instantly detects goroutine memory leaks, audits LLM connectivity, validates session vaults, and auto-repairs missing databases.

Remote Chat

Chat with your desktop agent from any browser. Your phone, a tablet, another computer, as long as the agent is running at home.

Vision

The agent can see your screen. Share a screenshot and get instant feedback on your code, design, or any visual content.

Multi-Provider

Connect to OpenAI, Anthropic, Google, DeepSeek, MiniMax, Kimi, or any OpenAI-compatible API. Use your own keys.

Triple-Layer SQLite Memory

Deep architectural persistence. Divides contexts into Episodic (events), Semantic (facts & preferences), and Procedural (recipes). The autonomous compressor retrieves precisely what is needed in milliseconds.

Aider-Grade Auto-Test Loop

No more human intervention needed. The internal Lint-Test loop natively executes formatters, builds `go test` or `pytest`, and feeds errors back into the agent context for instant self-correction.

Plugin Manager

Install, remove, and manage plugins directly from chat. Your agent maintains its own toolkit. Extend capabilities on demand.

Voice Input

Talk to your agent using speech-to-text. Supports OpenAI Whisper, Google, and local transcription for hands-free AI interaction.

System Monitor

Real-time CPU, RAM, and disk gauges with color-coded thresholds. Track your agent's resource usage with professional SVG arc visualizations.

3 Hours Free / Day

Use the full power of OsirisBrain for 3 hours every day, forever. Your agent knows how much time you have left and plans work efficiently within your budget.

Guardian Mode

Protect elderly users from phishing, scams, and online fraud. Heuristic fraud analysis with 40+ patterns, trusted contacts and banks lists, outgoing message scanning, and real-time alerts. Three protection levels. PIN-locked.

End-to-End Encryption

Your conversations are protected by military-grade AES-256-GCM encryption. Even when using the Web Remote Chat, your data is encrypted locally and passes through our servers as ciphertext. We cannot read your chats.

Parental Mode

Keep children safe online. Community blocklist sync, browser monitoring, process watcher, screen time limits with bedtime enforcement, and category-based content filtering. PIN-locked and tamper-proof.

Cortex Memory System

Your AI remembers.
Like a real brain.

Most AI agents start every conversation from scratch. OsirisBrain has a brain-inspired memory architecture. It knows who you are, what you're working on, and what matters to you. Across every session.

Semantic Memory
Temporal Lobe

What it knows

Facts, identity, project details, preferences. Permanent knowledge that never fades. Your agent knows your name, your stack, and your rules without being told twice.

Episodic Memory
Hippocampus

What happened

Conversations, decisions, events. Timestamped and searchable. "What did we discuss about the API last Tuesday?" Your agent remembers.

Procedural Memory
Cerebellum

How to do things

Workflows, habits, and patterns your agent learns from you. It knows how you deploy, how you like commits, and how you structure your code.

Emotional Context
Amygdala

What matters

Importance tagging inspired by the brain's emotional system. Critical priorities are recalled first. Low-priority memories naturally fade over time.

Active Commitments
Prefrontal Cortex

What it must do

Tasks, deadlines, responsibilities. Tracked until completed. Your agent greets you with a briefing of pending work, like a real colleague who never forgets.

Decision Engine
Basal Ganglia

When to act alone

Risk-scored autonomous decisions. Routine tasks run automatically. High-impact actions ask for approval. Dangerous operations are blocked. Just like a responsible colleague.

The first desktop AI agent with real cognitive architecture.

The Agent

Meet Osiris.
Your AI has a soul.

Osiris is not a chatbot. It is the chief agent — the one who commands every professional in your team. It learns, remembers, grows, and never forgets.

The Chief

Every professional reports to Osiris. It coordinates, delegates, and ensures consistency across your entire AI team.

Living Memory

Identity, episodic memories, patterns, emotional context, and every decision ever made. A real cognitive fingerprint.

Body Transfer

Export as a single .osiris file. Import on any machine. Same soul, new body.

Your AI doesn't die when you upgrade your laptop. It just changes bodies.

Security

Six layers of protection.

Every instruction the AI executes passes through a multi-layer security system before touching your machine.

01

Crystal Cage

Filesystem, process, and network whitelist. The agent can only access paths you've approved. Everything else is blocked.

02

AI Firewall

Every prompt and response is scanned for injection patterns. Dangerous commands like rm -rf and sudo are caught instantly.

03

Permission Semaphore

Actions are classified Green, Yellow, or Red. Red-level operations require explicit user approval via native dialog.

04

Allowlist Guardrails

Pattern validation rejects overly broad permissions. Only specific, approved paths and commands are allowed.

05

Risk Scoring

Every command is scored 1–10 before execution. High-risk operations are flagged with clear visual indicators.

06

File Snapshots

Automatic backups before any destructive file operation. One-click undo restores the original in seconds.
