Set Up Persistent Memory
| 🌐 Languages: English | Français |
Category: Organization Difficulty: Beginner Setup Time: 15 min
Goal
Stop repeating yourself. Without configuration, you re-explain your preferences, clients, and work habits at the start of every Cowork session. With a memory.md file and Desktop Commander, Cowork knows all of this automatically.
Prerequisites
- Cowork active (Pro or Max subscription)
- Claude Desktop installed and up to date
- 15 minutes for initial setup
Steps
Step 1: Install Desktop Commander
Desktop Commander is the official extension that enables persistent memory.
- In Claude Desktop, open the Customize tab (main navigation)
- Find Desktop Commander in the extensions list
- Click Install
- Restart Claude Desktop when prompted
See Getting Started Step 8 for details.
Step 2: Create memory.md
- In Finder, navigate to
~/Cowork-Workspace/ - Create a new text file named
memory.md - Open it with TextEdit or any text editor
Step 3: Fill In Your Memory
Copy the template for your business type (see next section) and adapt it to your situation.
Start simple, 5-10 lines is enough to begin. You’ll enrich it over time.
Step 4: Test That It Works
Open a new Cowork session and type:
Read ~/Cowork-Workspace/memory.md and summarize what you know about my business.
If Cowork accurately describes your context, the setup worked.
Step 5: Use It Every Session
From now on, start each conversation with:
Read ~/Cowork-Workspace/memory.md first. Then [your actual request]

Usage Tips
Start with 5-10 lines. A short memory.md is better than a complex one you never keep up to date. Add information as you notice what you keep repeating session after session.
Update regularly. If a client preference changes, a supplier shifts, or your payment terms evolve, update the file. Outdated information in memory.md can cause errors.
Share with a colleague if relevant. If a partner or assistant also uses Cowork, a shared memory.md (same file, same workspace) keeps output consistent across sessions.
Test monthly. Once a month, ask Cowork to summarize what it knows about your business. This confirms the file is being read and reminds you what it contains.
