# Build Your Own AI-Powered Wiki with Obsidian + Karpathy LLM Wiki + Ollama > Source: > Published: 2026-08-05 09:08:23+00:00 I’ve kept 330+ notes for years. Two years ago, I migrated from **Evernote** to **Obsidian** to build my own wiki/ knowledge base from multi-year saved documents. Not only technical ones, but any personal interests — how to fly DCS, riding motorcycles in mountains, photograph techniques — in both English and Chinese. I can query and chat with my wiki, pulling related topics across all my notes. Amazing, isn’t it? Found **Karpathy LLM Wiki** and got interested. It’s simpler than your expectation: There are tons of tutorials about how it works and its **architecture**/ **workflow**. I recommend: I won’t repeat them. There are complex variants, but I tried several and burned tokens for days — this is the simplest approach. I have a GPD Win4 gamepad with internal and external AMD GPUs. I wanted to test its limits running a local LLM — speed and summarization quality. Select a vault to start with. Start with a new vault and a few documents — LLM processing really takes time and costs money if using a public API. Install Karpathy LLM Wiki plugin through community plugin. Don’t install any other plugin yet — you won’t know which is which. Connecting to a public LLM is simpler, but I burned $10/ day for 3 days and switched to local. As long as ollama service is up, download a model. For instance: ``` ollama run qwen2.5:7b ``` Model size depends on your hardware’s vRAM capacity. The one I’m using requires around 6~ 7 GB vRAM. Google’s Gemma 4 would work too. Obsidian settings > Community plugins > Options (gear icon) of Karpathy LLM Wiki > Once set up, ingest (copy/ move) your files into the raw/ folder. Press Ctrl + P > Karpathy LLM Wiki ingest from folder > select raw/ folder. You should see GPU1 usage spike like the bottom-right screenshot above. The top-right is Graph View of my wiki built from 330+ documents — looks impressive. I’ve used **Arch Linux** for years, only kept Windows for gaming. Ditched it completely when Proton made Windows games run on Linux without performance penalty. **Arch Linux** can do almost everything I need — it’s now my only OS for work + leisure. btw, I use **Arch** [Build Your Own AI-Powered Wiki with Obsidian + Karpathy LLM Wiki + Ollama](https://blog.devgenius.io/build-your-own-ai-powered-wiki-with-obsidian-karpathy-llm-wiki-ollama-beba1cbbd2bc) was originally published in [Dev Genius](https://blog.devgenius.io) on Medium, where people are continuing the conversation by highlighting and responding to this story.
