Inheriting the lineage of information management and ideation methodologies\u2014from Jiro Kawakita’s “KJ Method” in the 1950s (Kawakita, 1967) and Tadao Umesao’s “An Art of Intellectual Production” in the 1960s (Umesao, 1969), to Yukio Noguchi’s “Super Organization Method” in the 1990s (Noguchi, 1993)\u2014the “KM Method 1.0 (Knowledge Management Method)” is a web-based approach that positions generative AI as an advanced, highly intelligent “intellectual partner,” enabling creative intellectual production at 10 to 100 times the efficiency of traditional practices.<\/p>\n\n\n\n

Two years after the debut of KM Method 1.0 in 2024, browser evolution and the rise of the Google AI ecosystem have dramatically transformed the environment for intellectual production. Centered around the Google Chrome browser\u2014commanding a 70% market share\u2014alongside the latest Gemini side panel and Gemini Notebook, this manual systematically details the practical procedures of the “Latest 2026 KM Method 2.0,” seamlessly unifying everything from information gathering to organization and writing.<\/p>\n\n\n\n

The Origins of KM Method 2.0: A Vision Born from Casual Conversation<\/strong><\/p>\n\n\n\n

The foundation of KM Method 2.0, KM Method 1.0, originated from a casual conversation between an acquaintance and myself. Sparked by their remark, “Wouldn’t it be great if there were a generative AI portal, or something like a meta-generative AI?”, I thought, “If no one is building it, I’ll build it myself,” which prompted me to begin development.<\/p>\n\n\n\n

“Is it just a daydream to wish for a generative AI portal, or a kind of meta-generative AI?”<\/p>\n\n\n\n

“Someone is probably already building one.”<\/p>\n\n\n\n

In April 2024, focusing on the Microsoft Edge browser’s “Copilot sidebar”\u2014state-of-the-art at the time\u2014I built the original “KM Method (1.0).” It operated by simultaneously opening “generative AIs such as ChatGPT, Copilot, and Gemini (on the right half of the screen)” and “information organization tools such as Notion and OneNote (on the left half).” This setup enabled systematic prompt management, efficient organization and archiving of AI-generated responses, and a smooth transition into content creation.<\/p>\n\n\n\n

Transitioning to “KM Method 2.0”: Leveraging New Chrome Features and the Google AI Ecosystem<\/strong><\/p>\n\n\n\n

Just two years after the introduction of the original KM Method, the browser landscape surrounding generative AI has evolved dramatically. As of 2026, updates to Google Chrome, which holds 70% of global market share, have made it possible to construct an advanced generative AI portal in an even more complete form\u2014a feat previously achievable only on Edge. This is “KM Method 2.0,” as presented in this manual.<\/p>\n\n\n\n

Underpinning KM Method 2.0 are AI interactions powered by the latest “Gemini side panel”\u2014which integrates seamlessly with browser tabs and side panels\u2014and the arrival of “Gemini Notebook” for centralized information management. By phasing out external, all-in-one note-taking apps as much as possible and centralizing information into the “Google AI Ecosystem,” where generative AI interfaces directly with data in Google Drive, the efficiency of intellectual production is maximized to the absolute limit. Furthermore, Chrome extensions now allow major generative AIs like ChatGPT and Claude to run right within the Chrome sidebar. Similarly, Chrome extensions make it possible to display a sidebar menu in Chrome that mirrors the Edge sidebar menu used in KM 1.0. By arranging shortcut icons for generative AIs, Google Workspace apps, primary information sources, and social media vertically in this panel, one can build a near-ideal “generative AI portal” directly inside the Chrome browser.<\/p>\n\n\n\n

The Tradition of Intellectual Production and the Paradigm Shift of “KM Method 2.0”<\/strong><\/p>\n\n\n\n

Tadao Umesao\u2019s “Three-Stage Model of Intellectual Production” and Information Standardization<\/em><\/p>\n\n\n\n

The concept of “intellectual production” was first introduced in the 1960s by cultural anthropologist Tadao Umesao (Umesao, 1969). Umesao defined it as “the operation of taking various existing or new pieces of information, applying an individual’s intellectual information-processing capacity to them, and producing new information,” describing it as a fundamental creative activity.<\/p>\n\n\n\n

The groundbreaking methodology devised by Umesao distinctly divided intellectual production into three stages\u2014”gathering information,” “organizing information,” and “producing content”\u2014consistently connecting them through “standardized cards.”<\/p>\n\n\n\n
