Why my private, AI-powered research and writing stack runs on a truly Open-Source tool, and it's not Obsidian

From a spark of an idea written on paper, grounded with Google's Deep Research and NotebookLM to a final published piece, my writing-publishing workflow lives inside a single, private, Open-Source ecosystem: Joplin. Let me show you my setup.

My process has three core stages, all connected within one central hub:

1. Research & Capture

The process starts with broad discovery using tools like Google Gemini (Deep Research). But once I find valuable articles, papers, or snippets, they need a home. For this, Joplin's Web Clipper is indispensable. I can save full web pages or simplified articles directly into my knowledge base, creating a rich, offline-first library of source material.

2. Writing & Synthesis

Now, many people in this space use and love Obsidian. It's a fantastic tool. But for me, a core principle was non-negotiable: the software must be truly #OpenSource. Obsidian is not. Joplin is. That was the decisive factor.

Plus: Joplin becomes an AI-powered studio with the Jarvis plugin. The key difference from the fragmented Obsidian ecosystem is that Jarvis is a single, cohesive suite that feels native to the app.

My writing process inside Joplin looks like this:

Crucially, by using local models, my research, notes, and drafts never leave my machine. This is the ultimate in privacy and control.

3. Publishing

The entire pipeline, from initial outlines and messy drafts to final, polished versions, is organized in Joplin notebooks. It’s my single source of truth before anything gets published.

This stack gives me the best of all worlds: the principles of open source, the security of local-first data, and a powerful, private AI assistant.

There's a fascinating ecosystem of tools out there. What does your personal knowledge stack look like? Share your setup below!
