Tobi Lütke

Tobi Lütke is the CEO of Shopify. In the context of the LLM Wiki ecosystem, he is notable as the creator of qmd — an on-device hybrid search engine for Markdown files.

Lütke created qmd, which combines BM25 full-text search, local vector embeddings, and LLM re-ranking to provide a powerful memory and search backend for agents operating over Markdown-based knowledge bases. qmd is positioned as the next step beyond the simple index.md catalog approach: it becomes useful once an LLM Wiki grows large enough that a flat index file alone is no longer sufficient for navigation and retrieval.

• qmd is part of the broader tooling stack that has emerged around the LLM Wiki pattern popularized by Andrej Karpathy.
• It serves as a bridge between the purely index-based approach of small-scale wikis and the full vector database infrastructure of RAG systems.
• It is designed to work alongside agents such as Claude Code and human-facing readers like Obsidian. [llm-wiki.en.md]
