01What Hermes Jarvis Obsidian Is and How It Works

Hermes Jarvis Obsidian is a setup that lets your AI agents, especially Hermes and Jarvis, read and write to your Obsidian notes. It uses a sync system that works across many devices, so your agents can use your notes even when your computer is off.

The key is a tool called the Sync MCP. This connects your Obsidian vault to your AI agents. You can choose to share the whole vault or just specific folders.

The agent can then use your notes to understand your projects and work automatically.

This setup is part of the AgentOS, which lets you plug in many agents together. You can even include a voice agent called Jarvis. The system handles the connection, and you can add devices by scanning a QR code.

02Main Features and What's New in AgentOS

The AgentOS brings all your AI tools into one system. You can connect Hermes, Claude, and other agents. It also includes a voice agent, a content analysis agent, and pop-up agents that are ready anytime.

Here are some key features:

  • Voice agent (Jarvis): Syncs with Hermes and works with your existing ChatGPT subscription, no extra cost.
  • Memory system: Stores information about you and your projects, so new agents know everything from day one.
  • Sync MCP for Obsidian: Shares vaults across devices and agents, with separate tokens per device and easy disconnection.
  • Tailscale integration: Links multiple devices for free so you can access your setup remotely.
  • Custom voices: You can connect voices from platforms like ElevenLabs to Hermes Apollo, but you must pay for the API.

These features are built to make automation simple and flexible. You can control your computer, open apps, and run workflows from anywhere.

03How to Set Up Hermes Jarvis Obsidian Step by Step

Setting up the sync between Obsidian and your agents is straightforward. Here is how you can do it, based on what was shown in the episode.

  1. Install the Obsidian Sync MCP on your server or main device.
  2. Choose whether to share the whole vault or only specific folders with your agent.
  3. In the agent that set up your AgentOS, ask it to link the Obsidian sync to your Hermes or Jarvis agent.
  4. Scan the QR code on each new device to add it to the sync system.
  5. Give each device its own token so you can disconnect them separately if needed.

That's it. The sync works with any AI agent, so you can use it with Hermes or others. You don't need a powerful computer; even an old MacBook Pro or Mac Studio works fine.

04How to Use It: Practical Examples from the Episode

In the episode, Julian showed how to answer community questions using the AgentOS. He used the content analysis agent to keep up with AI news and plugged it into the memory system.

For the voice agent, you can use it while working in Hermes chat or in mission control. You can speak to it anytime, open apps, or control your computer. It's always available, like a pop-up agent.

To change the voice in Hermes Apollo, follow these steps:

  • Get the API from a platform like ElevenLabs where you created your custom voice.
  • Go to Claude and open the conversation that set up your AgentOS.
  • Ask it to use your voice API instead of the default, giving the API documentation.

Then test it to make sure it works smoothly.

05Results and Comparisons Shown in the Episode

Julian noted that over the last year, AI agents have changed a lot. In 2025, there was a clear difference between autonomous agents like OpenClaw or Hermes and coding tools like Codex or VS Code. Now, that line is blurring.

He pointed out that features like scheduling and memory that were unique to agents are being added to coding tools. Even DeepSeek's Carnets feels built for agents, not just for coding.

He also tested the voice agent with a ChatGPT subscription. It worked without paying for a separate API. That is a big cost saver.

For the Obsidian sync, he confirmed it works across many devices. Each device gets its own token and can be disconnected separately. No data loss or conflicts were reported in the episode.

06Tips, Limits, and Mistakes to Avoid with Hermes Jarvis Obsidian

Here are some tips from the episode to make your setup smoother:

  • Don't worry too much about permissions for your agent. Restoring is easy, and issues are rare.
  • Use your existing ChatGPT subscription for the voice agent to avoid extra API costs.
  • For custom voices, remember you will have to pay for the API, which is why Julian sticks with the default.
  • Don't buy a new Mac Mini just for this. It works fine on any device.
  • Use Tailscale to link multiple devices for free. It takes only 10 minutes to set up.

A common mistake is trying to share too many folders at once. Start with just the folders you need. Also, make sure to ask the original setup agent for changes so it has context.

Finally, remember that agents and harnesses are merging. Pick one tool and learn it well rather than juggling many.

07Who Should Use Hermes Jarvis Obsidian and Why It Matters

If you are an entrepreneur, AI strategist, or someone building AI automations for clients, this setup is for you. It lets you manage everything in one place and automate more tasks.

For agencies, the episode mentions a full step-by-step course on scoping, pricing, and packaging AI services. That is inside the AI Profit Boardroom, but the concepts apply to any agent setup.

Using Hermes Jarvis Obsidian helps you keep all your knowledge and workflows connected. Your agents can access your notes, work automatically, and stay consistent with your projects. It's a practical way to scale your automation without extra cost or complexity.
