Build a second brain that works for you
Guides, comparisons, and methods for thinking better with AI. No fluff. No hype. Just what works.
How to use AI for
How to use AI for meeting notes
Stop transcribing meetings manually. Here's how AI captures, structures, and connects your meeting notes so nothing falls through.
How to use AI for research
Research generates more material than you can process. AI helps you capture, connect, and find insights across hundreds of sources.
How to use AI for journaling
Journaling with AI doesn't mean a robot writes your entries. It means patterns in your thinking surface that you'd miss otherwise.
How to use AI for idea generation
Ideas don't come from nowhere. They come from connecting things that haven't been connected yet. AI speeds up the connecting.
How to use AI for content creation
Content creation is research, writing, and revision. AI helps at every stage without writing for you.
How to use AI for project planning
Project plans are decisions, timelines, and people. AI helps you learn from past projects before starting the next one.
How to use AI for decision making
Good decisions come from good context. AI surfaces the relevant past decisions, research, and data before you decide.
How to use AI for learning
Learning is connecting new information to existing knowledge. AI helps you do that at scale without losing depth.
How to use AI for goal setting
Goals disconnected from your daily thinking become abandoned resolutions. AI keeps your goals surfaced in the context where they matter.
How to use AI for weekly planning
A weekly review is the most productive hour of your week. AI makes it faster and more insightful.
Second brain setup guides
Second Brain Setup: Zettelkasten
The Zettelkasten method is the gold standard for networked thought. Here's how to set it up with AI so the linking happens automatically.
Second Brain Setup: PARA Method
Tiago Forte's PARA method organizes everything into Projects, Areas, Resources, and Archives. Here's how to make it work with AI.
Second Brain Setup: GTD Workflow
David Allen's Getting Things Done is the original productivity workflow. Here's how AI keeps the capture-clarify-organize-review cycle running without the upkeep.
Second Brain Setup: Building a Second Brain (BASB)
Tiago Forte's BASB framework is the most popular second-brain system. Here's how to implement CODE — Capture, Organize, Distill, Express — with AI doing the heavy lifting.
Second Brain Setup: Maps of Content
MOCs are curated index notes that navigate your knowledge graph. Here's how AI helps you build and maintain them.
Second Brain Setup: Linking Your Thinking
Nick Milo's LYT framework uses six principles for a networked thinking system. Here's how AI accelerates every principle.
Second Brain Setup: Digital Garden
A digital garden grows your ideas in public, with each note maturing over time. Here's how AI helps tend the garden.
Second Brain Setup: Bullet Journal for Geeks
The Bullet Journal method is analog by design. Here's how a digital second brain can capture its best ideas while adding intelligent connections.
Tool comparisons
tentus vs Notion
If you want a tool that organizes itself, tentus. If you want to build your own system from scratch, Notion.
tentus vs Obsidian
Obsidian for the builder who loves tinkering. tentus for the knowledge worker who wants thinking, not maintenance.
tentus vs Roam Research
Roam was the first. tentus is what comes next — proactive, automated, always on.
tentus vs Mem
Both are AI-native. tentus goes further — Lumi anticipates what you need before you search.
tentus vs Reflect
Reflect for quick capture and AI search. tentus for proactive briefings, workflows, and a connected second brain.
tentus vs Tana
Tana rewards system-builders. tentus rewards people who just want it to work.
tentus vs Logseq
Logseq for privacy-first, open-source advocates. tentus for people who want proactive intelligence across all contexts.
tentus vs Bear
Bear for beautiful markdown on Apple devices. tentus for a connected second brain everywhere.
tentus vs Capacities
Capacities if you enjoy classifying. tentus if you want Lumi to do that work for you.
tentus vs Craft
Craft for polished documents. tentus for connected thinking that surfaces insights automatically.
Notion vs Obsidian
Notion for teams who need databases and collaboration. Obsidian for individuals who want complete control.
Notion vs Roam Research
Notion for project management and wikis. Roam for researchers and networked thinking.
Best note-taking method for
Product Managers
juggling research, specs, stakeholder feedback, and launch plans across multiple tools.
Software Engineers
losing context between code reviews, incident postmortems, and technical research.
Designers
scattered moodboards, design critiques, and research that never gets referenced again.
Researchers
drowning in PDFs and citations with no way to connect findings across projects.
Writers
notes spread across drafts, interviews, and research that should connect but don't.
Entrepreneurs
too many signal sources, too few systems to surface what matters.
Consultants
context-switching across clients with no bridge between engagements.
Students
notes vanish after the exam because there's no system to revisit them.
Project Managers
decisions buried in Slack threads, email chains, and meeting notes.
Marketing Managers
competitive intel and campaign learnings scattered across docs and tools.
Data Scientists
experiment notes and model documentation that never gets shared or built upon.
Journalists
interview transcripts, source contacts, and story threads that don't connect.
Executives
too much to read, too little time, no system that distills what matters.
Creatives
fleeting ideas and visual references that dissolve before they become work.
Remote Workers
no watercooler — context lives in isolation across time zones.
