This piece is for you. It explains how Claude Code memory actually works, checked against Anthropic&rsquo;s own docs on 9 October 2026, what it can&rsquo;t do, and how I give it one memory across every project and tool I use.</p> <p>The short version: Claude Code remembers through two sets of files on your machine. You write one (CLAUDE.md). Claude writes the other (auto memory). Both are local, and auto memory is per project. If you want the same memory in every project, on every machine and in other AI tools, you need something outside Claude Code, and the supported way to plug that in is an MCP server.</p>https://tryultrathink.com/blog/second-brain-system-build/Wed, 28 Jan 2026 00:00:00 +0000https://tryultrathink.com/blog/second-brain-system-build/Why second brain systems fail within months, and how to design one for longevity: instant capture, automatic organisation and low upkeep.https://tryultrathink.com/blog/notion-vs-obsidian-mistake/Wed, 28 Jan 2026 00:00:00 +0000https://tryultrathink.com/blog/notion-vs-obsidian-mistake/Why the databases-versus-markdown argument misses the point, and why many people abandon whichever tool they pick within months.https://tryultrathink.com/blog/second-brain-notion-guide/Wed, 28 Jan 2026 00:00:00 +0000https://tryultrathink.com/blog/second-brain-notion-guide/Why Notion second brains get abandoned, what Notion is good at, and a capture-first alternative for fast ideas.https://tryultrathink.com/blog/second-brain-app-comparison/Wed, 28 Jan 2026 00:00:00 +0000https://tryultrathink.com/blog/second-brain-app-comparison/Why feature lists mislead when you choose a second brain app, and why consistent capture beats the strongest tool.https://tryultrathink.com/blog/second-brain-method-simplified/Wed, 28 Jan 2026 00:00:00 +0000https://tryultrathink.com/blog/second-brain-method-simplified/A simplified second brain method for busy professionals: drop the frameworks, capture quickly and let search and AI do the sorting.https://tryultrathink.com/blog/second-brain-myth/Wed, 28 Jan 2026 00:00:00 +0000https://tryultrathink.com/blog/second-brain-myth/Why most second brain systems are abandoned within weeks, and practical ways to keep yours going past the 90-day mark.https://tryultrathink.com/blog/second-brain-app/Sun, 18 Jan 2026 00:00:00 +0000https://tryultrathink.com/blog/second-brain-app/A guide to second brain apps: what they are, the features that matter, and ten apps compared for memory and focus.
