Has anyone else used AI to analyse their PKM? Claude flagged my vault clusters around AI, tech, gaming, finance, and health — but missed philosophy entirely. I'd have expected that one. What would yours show? #PKM #Obsidian

Claude's vault analysis broke down into six sections: knowledge gaps, connection patterns, pipeline health, MOC coverage, content ideas, and workflow stats. Each one flagged something I'd have missed on my own. www.ctnet.co.uk/ai-obsidian-... #PKM #Obsidian #AI

I got Claude Code to analyse my entire Obsidian vault — 30 minutes, £7 in tokens, and a six-section report. Gaps I hadn't noticed, connections I'd missed, content I can actually write. Full breakdown: www.ctnet.co.uk/ai-obsidian-... #PKM #Obsidian

I'm writing about AI reliance, but I still let Claude edit this post. That tension is worth being honest about. My reasoning is in my Q1 review - worth a read if you're navigating the same questions. www.ctnet.co.uk/my-ai-quarte... #AI #PKM

Do you review how you use AI? I run a quarterly check covering reliance, new capabilities, cognitive impact, and my red lines. What does your AI use look like compared to three months ago? www.ctnet.co.uk/my-ai-quarte... #AI #PKM

Using AI for editing: starting point or end point? I use it to track patterns in my writing and build checklists. The AI helps me improve, rather than doing it for me. Thoughts from my Q1 review: www.ctnet.co.uk/my-ai-quarte... #PKM #AI

First quarterly AI review is up. Honest self-assessment of where I'm relying on AI (writing more than I'd like), what's changed in Q1 2026, and whether I stayed on the right side of my red lines. www.ctnet.co.uk/my-ai-quarte... #PKM #AI

I hadn't planned to get a Claude subscription in December. But comparing Claude and Gemini for Obsidian integration, Claude won. Six months later it's changed how I write and think. Post 2 of the journey: www.ctnet.co.uk/claude-obsid... #PKM

Writing the first draft is one of my red lines when using AI with my PKM - it's how I think. Do you have similar boundaries with AI in your knowledge work? www.ctnet.co.uk/claude-obsid... #PKM #AI

I've built Claude Code skills for: indexing my Zettelkasten, suggesting tags, editing blog posts, and SEO/social media. Admin tasks that used to eat time. Writing the first draft stays mine. www.ctnet.co.uk/claude-obsid... #PKM

Part 2 of my Claude + Obsidian journey is live. Three versions of Claude, each doing something different in my PKM workflow. I share what's changed since December. www.ctnet.co.uk/claude-obsid... #Obsidian #PKM

One thing I didn't expect to highlight in my Obsidian review: its AI flexibility. It has no built-in AI, which means you choose if and how you use it. That's increasingly rare. www.ctnet.co.uk/obsidian-rev... #Obsidian #AI

How do you actually use Obsidian? I use it for PKM, journaling, and writing, but I know of people who use it purely for tasks or writing fiction. Curious what your setup looks like. #Obsidian #PKM

One thing that makes Obsidian different: if it disappeared tomorrow, your notes would still be there, plain text files on your computer. That peace of mind matters more than I realised. www.ctnet.co.uk/obsidian-rev... #PKM

Just published my 2026 Obsidian review. New features like Bases and the web clipper have changed things, but has it changed enough to stay my top PKM pick? www.ctnet.co.uk/obsidian-rev... #Obsidian #PKM

"A PKM isn't about storing information. It is a personal architecture aimed at helping you to think and remember."

Not a note store. A thinking tool. www.ctnet.co.uk/pkm-cognitiv... #PKM #Zettelkasten

Has AI changed how you approach learning and note-taking? I've been wrestling with this — where does helpful AI assistance end and outsourced thinking begin? www.ctnet.co.uk/pkm-cognitiv... #PKM #AI

The three red lines I've set for AI in my Zettelkasten:

1. I write my own literature notes
2. I write my own permanent notes
3. I create my own links between notes

AI can suggest, but not replace the thinking. www.ctnet.co.uk/pkm-cognitiv... #PKM #AI

Five years of Zettelkasten has convinced me: a PKM system isn't just for storing ideas — it can actively protect how you think in an AI world. Final post in my series: www.ctnet.co.uk/pkm-cognitiv... #PKM #Zettelkasten #AI

I include this in the system prompt of every AI I use: 'Give honest and constructive feedback.' I want AI to push back on my thinking, not just agree with me. www.ctnet.co.uk/protecting-y... #AI #PKM

Do you ever worry about becoming too reliant on AI for thinking? I've started including a quarterly check-in to audit my own AI use — five questions I ask myself. www.ctnet.co.uk/protecting-y... #AI #PKM

A useful rule of thumb for AI: offload what you already do on autopilot (System 1), but don't outsource what you're still actively learning (System 2). That's where growth happens. www.ctnet.co.uk/protecting-y... #AI #PKM

'The ability to think for oneself is a deliberate practice developed by being curious about your own thoughts.' From the latest post in my AI and cognition series: www.ctnet.co.uk/ai-knowledge... #AI #PKM

Do you think deliberately about protecting your own cognitive skills? I didn't used to. Writing this series on AI and human cognition has made me realise I need to be more intentional about this. www.ctnet.co.uk/ai-knowledge... #AI #PKM

How can we know if AI is conscious when we can't even prove other humans are? This question from The Sentient Machine has been rattling around my head for a while. What do you think? www.ctnet.co.uk/the-sentient... #AI #Philosophy

Three ways to protect yourself from knowledge collapse: don't rely totally on AI, invest in specialist knowledge, and push back on AI training on AI-generated data. Easy to say. Worth doing. www.ctnet.co.uk/ai-knowledge... #AI #PKM

Research shows AI-generated content is already narrower than what humans create alone. If AI trains on AI content, that narrowing compounds. This is knowledge collapse — and it's a risk worth taking seriously: www.ctnet.co.uk/ai-knowledge... #AI #KnowledgeManagement

We have a window to shape our relationship with AI — but we don't know how long it stays open. Could be years, decades, or millennia. Either way, the time to start asking the questions is now. www.ctnet.co.uk/the-sentient... #AI #ArtificialIntelligence

Yuval Noah Harari argues that language is the operating system of human civilisation. We've now handed AI the key to that OS. This post explores what that means — and why it's worth sitting with. www.ctnet.co.uk/the-sentient... #AI #ArtificialIntelligence
