Verdict: The most effective way to solve "AI amnesia" is to shift your agent’s state from the model to a local Obsidian vault. By bridging your notes to agents via the Model Context Protocol (MCP), you create a persistent memory loop where every interaction makes your AI smarter, more personalized, and more context-aware without manual retraining.
Last verified: June 26, 2026
Systems required: Obsidian (Free), Omi App (Open Source), and an MCP-compatible agent (Claude Code / Hermes).
Status: Fully operational; requires no cloud subscriptions for the core memory layer.
Why your AI agents have "Amnesia" (and how to fix it)
Standard AI agents are stateless. Every time you open a new chat window in Claude, ChatGPT, or a CLI, the model starts from zero. You spend the first 10 minutes re-explaining your brand voice, your current project goals, and your client list. This "blank slate problem" is the primary barrier to true AI productivity.
The solution is an Infinite Context Engine. Instead of relying on the model's short-term context window, you maintain a "Second Brain" in Obsidian that your agents can query and update in real-time.
The 4-Layer Memory Loop
- Capture (Omi): A background app records your screen, meetings, and thoughts, auto-transcribing them.
- Store (Obsidian): These transcripts are exported into a local markdown vault.
- Connect (MCP): A Model Context Protocol server lets your AI agent "read" your vault files like a database.
- Learn (The Loop): The agent writes a summary of every session back into the vault, ensuring tomorrow's agent knows what today's agent did.
The Setup: Building your Memory Vault
Step 1: Initialize your Obsidian Vault
If you don't already use Obsidian, download it (it's free and local-first). Use the PARA method to organize your folders:
- Projects: Active work with deadlines.
- Areas: Ongoing responsibilities (e.g., Marketing, Finance).
- Resources: Your library of interests and references.
- Archives: Completed work.
Step 2: Configure Omi for Background Capture
Omi is an open-source capture tool. While they sell a wearable necklace, the Omi Desktop and Mobile apps are free to use for recording.
- Install the Omi app on your workstation.
- Enable "Export to Obsidian" in the settings.
- Omi will now quietly transcribe your meetings and screen activity into daily notes in your vault.
Step 3: Bridge the Vault to your Agents via MCP
To let an agent like Claude Code or Hermes Agent see your notes, you need an MCP bridge.
Recommended Tool: obsidian-mcp-server (or the Vault as MCP plugin).
Add this to your mcp_config.json:
{
"mcpServers": {
"obsidian": {
"command": "npx",
"args": ["-y", "@iansinnott/obsidian-claude-code-mcp"],
"env": {
"OBSIDIAN_VAULT_PATH": "/absolute/path/to/your/vault"
}
}
}
}
The "Infinite Context" Workflow
Once connected, you no longer paste context. You simply reference it.
1. The Morning Briefing
Start your day by asking your agent:
"Read my daily notes from yesterday and summarize my progress on the 'Q3 Launch' project. What are my top 3 priorities for today?"
Because the agent has automated learning capabilities, it will scan your Omi transcripts and Obsidian links to give you a perfectly contextual answer.
2. The Auto-Updating Memory
At the end of a session, use a "Handoff" command. Instruct your agent:
"Write a brief summary of what we just decided to my
Log/2026-06-26.mdfile."
This ensures that even if you switch agents or start a new thread, the next session begins with the most recent state. This prevents the cognitive debt that comes from managing fragmented AI conversations.
What this means for you
For small business owners, this system transforms AI from a "chatty assistant" into a Stateful Coworker.
- Zero Setup Time: Your agent already knows your preferred tech stack and client names.
- Total Privacy: Your memory vault lives on your machine in plain markdown files.
- Infinite Scale: As your vault grows over months and years, your AI's "IQ" effectively increases because it has more historical data to draw from.
FAQ
Q: Is Omi really free? A: The Omi software is open-source and free to download for macOS, Windows, and mobile. The wearable $129 necklace is optional hardware for better audio capture on the go, but not required for the memory system to work.
Q: Doesn't this bloat the AI's context window? A: No. By using MCP, the agent only "reads" the specific files it needs for a query, rather than loading the entire vault. This keeps costs low and speed high.
Q: Can I use this with ChatGPT? A: As of mid-2026, ChatGPT lacks a native local MCP bridge. This system works best with agents that support local file access or the Model Context Protocol, such as Claude Code, Cursor, or Hermes Agent.
Q: Is my data safe? A: Because Obsidian is local-first, your raw notes never leave your machine unless you explicitly use a cloud sync service. When an agent reads your vault, it only sees what is necessary for the current task.
