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
A practical, no-bot workflow for recording a meeting, checking the transcript and generated briefing, and carrying the decisions into your next step.
How to use AI for research
Build a small, checkable research note with source links, competing claims and explicit gaps.
How to use AI for journaling
Review your own dated entries with optional AI assistance, while keeping interpretation separate from what you recorded.
How to use AI for idea generation
Turn a few saved observations into ideas you can explain, challenge and test.
How to use AI for content creation
Draft from a bounded set of notes, verify each claim and preserve the sources behind the published piece.
How to use AI for project planning
Build a project plan from checked decisions, unresolved assumptions and a concrete next action.
How to use AI for decision making
Use saved evidence to compare options, expose uncertainty and record why you chose a direction.
How to use AI for learning
Practice recall from a small set of saved material, then check your explanation against the original.
How to use AI for goal setting
Connect a goal to explicit evidence and a review habit without treating saved activity as automatic progress.
How to use AI for weekly planning
Review dated notes, verify open commitments and choose next week’s work in a manual planning session.
Second brain setup guides
Second Brain Setup: Zettelkasten
A practical linked-note exercise: write one idea, explain its connections and revisit the source.
Second Brain Setup: PARA Method
Apply Projects, Areas, Resources and Archives through a small, deliberate review of your notes.
Second Brain Setup: GTD Workflow
Use capture, clarification, organization and review to turn notes into decisions about what to do next.
Second Brain Setup: Building a Second Brain (BASB)
Practice Capture, Organize, Distill and Express using a small collection and a concrete output.
Second Brain Setup: Maps of Content
Build a useful index note from a few sources, explain each link and maintain it through deliberate review.
Second Brain Setup: Linking Your Thinking
Practice deliberate linking and write your own explanations of how notes relate.
Second Brain Setup: Digital Garden
Develop notes through explicit revision and review them carefully before sharing.
Second Brain Setup: Bullet Journal for Geeks
Adapt rapid logging and deliberate migration to digital notes while keeping review in your hands.
Tool comparisons
tentus vs Notion
Notion is a good fit when you want a configurable workspace for documents and projects. tentus is designed as a second brain with Lumi across connected sources; verify the workflow and access you need during early testing.
tentus vs Obsidian
Consider Obsidian when local files and a workflow you can customize matter most. Evaluate tentus for Lumi-assisted recall during early testing, checking source coverage, export and access before moving your notes.
tentus vs Roam Research
Test your own linked-note workflow in Roam and compare the result with Lumi-assisted recall when tentus access is available. We do not claim that Roam lacks automation or that tentus is its successor.
tentus vs Mem
Mem is a good fit if its meeting, Chat, and Heads Up workflow matches your needs. tentus is designed as a second brain with Lumi across connected sources; test the exact workflow and current availability before choosing.
tentus vs Reflect
Consider Reflect if its local-file and linked-note approach fits your devices. For either product, test a real question, inspect its cited notes and confirm how optional AI processing and access work.
tentus vs Tana
Consider Tana Outliner when typed notes and reusable views fit your workflow. Evaluate tentus for Lumi-assisted work with saved sources during early testing. Compare the exact Tana product and workflow you intend to use.
tentus vs Logseq
Consider Logseq if an open-source graph workflow fits your needs. Check the specific graph version, backup and sync guidance. For tentus, confirm available access, source coverage and export before relying on it.
tentus vs Bear
Consider Bear for an Apple-focused writing and note workflow. Evaluate tentus if you want to test Lumi-assisted recall, and confirm platform access, capture limits and export rather than assuming parity across devices.
tentus vs Capacities
Consider Capacities if objects and their relationships fit how you organize knowledge. Evaluate tentus with the same saved sources, checking whether Lumi retrieves useful evidence and how you correct incomplete answers.
tentus vs Craft
Consider Craft for a document-centered workflow with tasks and calendar context. Evaluate tentus for source-backed recall during early testing. Verify sharing, export and current access in each account.
Notion vs Obsidian
Evaluate Notion for searching material in a shared workspace and Obsidian for a local-file workflow you can customize. Check source coverage, sharing, export and any optional services with your own material.
Notion vs Roam Research
Compare a concrete task: save related notes, retrieve one decision and export its context. Check current Roam documentation and account features before drawing conclusions about automation or AI; no feature-parity verdict is established here.
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.
