Build your AI writing system — Tiago Forte talk

Tiago Forte, known for the Building a Second Brain methodology, walks through how to construct an AI writing system from the ground up. Rather than reviewing individual tools, Forte focuses on the architecture of a writing workflow that uses AI at every stage from idea capture to publication.

Who it’s for

Knowledge workers, bloggers, and content creators who already have a note-taking or personal knowledge management practice and want to integrate AI into it systematically rather than using AI tools in isolation.

Key takeaways

1. A writing system is more than a collection of tools. Forte emphasizes defining the stages of your writing process first and then assigning AI capabilities to each stage, rather than adopting tools and hoping they fit.

2. The connection between your note archive and your AI tools determines how personal and accurate the outputs will be. Forte demonstrates how feeding accumulated notes into AI produces writing that reflects your actual thinking rather than generic model outputs.

3. The handoff points between human thinking and AI assistance need explicit design. Forte identifies which stages benefit from AI speed (research synthesis, first-draft generation, formatting) and which stages require human judgment (thesis formation, voice, ethical framing).

4. Iteration loops matter more than prompt quality. A mediocre first prompt followed by three rounds of refinement typically outperforms a single carefully crafted prompt, because each round gives the model more context about what you actually want.

Worth watching if…

You have an existing knowledge management system (Notion, Obsidian, or similar) and want a framework for connecting it to AI writing tools in a way that produces outputs grounded in your own ideas and research.
