Build an AI second brain

Matt Giaro published the guide on his Substack newsletter "The AI Blogger," where he posts regular tactical pieces about AI and content systems. (substack.com/@mattgiaro) The material on his main site expands those tactics into platform-specific how‑tos, including an Obsidian setup post that says his vault contains 4,819 notes and that the system "powers" a six‑figure writing business. (mattgiaro.com/second-brain-obsidian/) Giaro pairs note apps with large language models in practice: his site publishes step‑by‑step ChatGPT prompts and recipes for proofreading and for generating headline options. (mattgiaro.com/proofread-chatgpt/) (mattgiaro.com/chatpgt-article-headlines/) He sells a paid curriculum called "Second Brain for Content Creators" that lists modules on note types, graph‑view optimization and content recycling, and the course includes templates and lecture components on learn.mattgiaro.com. (mattgiaro.com/courses/second-brain-for-content-creators/) (learn.mattgiaro.com/courses/1884605/lectures/43063199) Giaro takes explicit positions on methodology: he has a standalone post arguing against the CODE (Capture/Organize/Distill/Express) framework and a separate piece contrasting Zettelkasten with other "second brain" approaches. (mattgiaro.com/code-second-brain/) (mattgiaro.com/zettelkasten-vs-second-brain/) He promotes the guide across channels—his YouTube channel lists about 5.15K subscribers and his website repeatedly links to free starter templates and an email course to onboard readers into the workflows he describes.
