How To Set Up Persistent Memory In OpenClaw

OpenClaw memory persistence setup takes about an hour — install OMI, configure Obsidian, link via MCP, and your AI agent finally remembers you.

By the end of this post:

OMI installed.
Obsidian connected for knowledge sync.
OpenClaw plugged into the memory system.
Persistent memory working.

Prerequisites

Three things first.

1 — OpenClaw running

If you don't have it, see Build Your Own OpenClaw.

2 — A Mac (for OMI)

OMI is Mac-primary right now.

Other platforms in development.

3 — About 60 minutes

Total setup time.

Step 1 — Install OMI

Download OMI:

omi.me (or the relevant distribution).
Open source — you can self-host.
Mac app available.

Install like a normal app.

Step 2 — First-Time OMI Configuration

On first open:

Configure permissions (microphone, screen recording).
Choose what to capture.
Set privacy preferences.

Be deliberate about what to capture.

For most users:

Microphone: yes (captures conversations).
Screen: optional (more privacy concerns).

Step 3 — Test OMI Capture

Have a 2-minute conversation with someone (or speak out loud).

OMI should capture and transcribe.

Check the conversations tab to verify.

Step 4 — Install Obsidian

Free.

Download from obsidian.md.

Install like a normal app.

Step 5 — Create An Obsidian Vault

In Obsidian:

Create a new vault for OMI exports.
Name it "OMI Memory" or similar.
Choose a local folder.

Step 6 — Connect OMI To Obsidian

In OMI's Apps section:

Find Obsidian integration.
Enable.
Point at your Obsidian vault location.

OMI will export captured memories to Obsidian as markdown.

Step 7 — Verify The Sync

Check your Obsidian vault.

You should see:

New markdown files.
Memory contents from OMI.
Knowledge graph populating.

If syncing isn't working:

Check OMI logs.
Confirm Obsidian vault path is correct.
Restart both apps.

Step 8 — Connect OMI To OpenClaw

OMI has an MCP (Model Context Protocol) server.

In OpenClaw config:

Add OMI MCP server endpoint.
Authenticate if needed.
Save config.

Step 9 — Test The Persistence

In OpenClaw chat:

Ask: "What have I been working on this week?"
OpenClaw should query OMI's memory.
Return contextual answer based on your captures.

If response is generic, the connection isn't working.

Re-check MCP config.

Step 10 — Set Up Skills (Optional)

Once persistence works, add skills:

Memory-aware skills that use OMI context.
Workflow skills that reference your knowledge base.

These compound the persistence value.

Common Setup Issues

1. OMI permissions denied.

Mac requires explicit permissions for mic + screen.

System Settings → Privacy & Security → enable for OMI.

2. Obsidian sync not happening.

Check vault path in OMI config.

Make sure Obsidian is closed when OMI writes.

3. MCP connection fails.

Check OMI MCP server is running.

Verify endpoint URL.

Check OpenClaw MCP config syntax.

4. OpenClaw doesn't use the memory.

Confirm in chat by asking about something you discussed previously.

If still generic, check MCP integration is active.

What To Do After Setup

Three steps.

1 — Use OMI for a week

Let it capture your daily activity.

Memory grows.

2 — Test OpenClaw with personal queries

Ask about your projects.

Ask about decisions you've made.

Verify it knows.

3 — Build memory-aware workflows

Now that OpenClaw has context, build workflows that depend on it.

E.g. "Draft a follow-up email based on my conversation with [person] yesterday."

Privacy Configuration

Before going live, configure privacy:

What to exclude

Password-typing screens.
Banking apps.
Confidential documents.
Personal medical info.

What to include

Work conversations.
Project discussions.
Idea brainstorms.
General knowledge work.

Be deliberate.

You can adjust anytime.

Setup Time Reality

Honest numbers.

OMI install: 5-10 minutes.
Configuration: 10-15 minutes.
Obsidian setup: 5 minutes.
Sync setup: 10 minutes.
OpenClaw MCP integration: 15-20 minutes.

Total: 45-60 minutes.

After that, daily use is automatic.

What Setup Doesn't Include

You set up the memory layer.

You don't:

Pre-populate memory (it grows organically).
Get AI quality improvements automatically (model-dependent).
Solve all context problems (some still need manual prompts).

For 80% of memory persistence needs, this setup covers it.

Hardware/Storage Considerations

OMI uses:

Local disk (memory storage).
CPU when capturing.
Some RAM when active.

Modern Mac handles fine.

For low-spec machines, configure conservative capture settings.

Pairing With Other Tools

This stack works alongside:

OpenClaw computer use for desktop automation.
OpenClaw Mission Control for agent management.
Auto Research Claw for deep research workflows.

Each layer adds capability.

Daily Reality After Setup

What it looks like:

OMI captures throughout the day automatically.
Obsidian fills with structured memory.
OpenClaw pulls context when you ask questions.
Agent responses are personalised.

You don't manage the memory system.

It manages itself.

FAQ — OpenClaw Memory Persistence Setup

Is the setup really 60 minutes?

For first-time install, yes.

After that, daily use is hands-off.

Do I need OMI specifically?

For this exact stack, yes.

Alternatives exist but OMI is the most mature.

Will Obsidian work on Windows?

Yes — Obsidian is cross-platform.

OMI is Mac-primary currently.

Can I delete my memory data?

Yes — anytime.

Will the memory affect OpenClaw performance?

Minimal — MCP queries are fast.

What if I don't have a Mac?

Wait for OMI Windows/Linux versions.

Or use alternative memory stacks (less mature).

Can I share memory across multiple AI agents?

Yes — same MCP can serve OpenClaw, Hermes, Claude Code, etc.
