Notes and files: Obsidian, Nextcloud and Google Drive
The difference between these three is where the data sits and who else can read it. Obsidian is a local folder of Markdown the agent reads directly. Nextcloud is a server you run. Google Drive is a third-party API and the only one of the three where the content leaves your control. That distinction should drive the choice more than the feature list.
Obsidian
/** "What did I write about RAG last month?" — searches 2000 notes in 2 seconds */
// Obsidian vs Notion — when to choose Obsidian
🏗 Architecture: Local Vector Search
Reads all .md files, generates embeddings, stores in local vector DB (no cloud)
Semantic search finds the most relevant notes for your question

Nextcloud: Private Workspace AI
/** Turn OpenClaw into your ultimate digital assistant. Let it search your PDFs, schedule meetings via CalDAV, and organize your Deck boards—all while keeping your data strictly off Big Tech servers. */
AI Document Intelligence & RAG
Nextcloud is the gold standard for self-hosted data. By securely connecting OpenClaw via WebDAV and the Model Context Protocol, your AI agent gains 'Document Intelligence'. It can vectorize your private PDF library for RAG (Retrieval-Augmented Generation), find specific invoices, or summarize long meeting minutes without your data ever leaving your infrastructure.
1. Security: Generating App Passwords
To maintain security, never use your primary password. Generate a dedicated, revokable App Password for OpenClaw in your Nextcloud Security settings.
- →Log in to your Nextcloud instance.
- →Settings → Security → Devices & sessions.
- →Create 'OpenClaw-Agent' password.
- →Copy the 20-character secret code.
2. The Nextcloud-MCP Bridge
We use a high-performance WebDAV bridge. Install it via npm and register the endpoint in your local OpenClaw configuration.
3. Pro-Level Capabilities
🛡️ Data Sovereignty & Rate Limits
Your privacy is paramount. Ensure your Nextcloud brute-force protection (fail2ban) is configured to trust your OpenClaw internal IP. For large libraries, the first scan may take several minutes as the agent builds its local semantic index.
Google Drive Integration
/** Connect OpenClaw to Google Drive to query, analyze, and generate content based on your Docs, Sheets, and Slides. */
Why integrate Google Drive?
Directly connect your primary document repository to your self-hosted AI.
📄
Ask OpenClaw to summarize meeting notes or long proposals directly from your Drive.
📊
Extract insights from CSVs and Google Sheets without manually exporting them.
🔍
Find semantic answers across all your Drive files, not just keyword matches.
🔒
Your Google Drive data remains between your self-hosted OpenClaw instance and Google. No third-party API in the middle.
How it works
Configure an OAuth application in Google Cloud Platform and securely mount your Drive.
Create a project in GCP and enable the Google Drive API.
Create an OAuth client ID and download the credentials JSON.
Add your GCP credentials to OpenClaw's environment variables.
Log in to your OpenClaw dashboard and connect your Google account securely.
