How to Build a Second Brain with Krokanti Notes

The "second brain" idea — a personal system for capturing and organizing everything you know — has been popular since Tiago Forte published his book on the subject. But most implementations are overcomplicated.

Notion databases. Obsidian vaults with 47 plugins. Backlink graphs. Zettelkasten IDs. People spend more time building the system than using it.

Here's a simpler approach that actually works — and requires nothing more than Krokanti Notes.

What a second brain actually is (and isn't)

A second brain is a trusted external system for capturing and retrieving information. The goal is simple: when you have an idea, learn something useful, or encounter a problem — you capture it. When you need it later, you can find it.

It is not:

• A productivity art project
• A perfectly organized knowledge graph
• Something that requires ongoing maintenance to stay functional
• Worth more time to maintain than it saves

The Krokanti Notes second brain setup

Step 1: Create your core folders

Start with five folders — no more:

📁 Inbox
📁 Projects
📁 Reference
📁 Archive
📁 Journal

Inbox — every new note goes here first. Don't decide where it belongs immediately; just capture.

Projects — one note per active project. Use checklists for tasks, headers for sections.

Reference — things you'll want to look up again: recipes, how-tos, commands, contacts.

Archive — completed projects, old notes worth keeping but not active.

Journal — dated entries for reflection, decisions, and retrospectives.

Step 2: Use tags as cross-folder connectors

Folders organize by context. Tags organize by topic, cutting across contexts.

Useful tag examples:

• #idea — thoughts worth developing
• #book — reading notes
• #decision — important decisions made and why
• #review — things to revisit periodically
• #question — open questions

A book note lives in Reference but has #book and #productivity tags. A project decision lives in Projects but has #decision and the project name as tags. Search by tag to find everything related to a topic across all folders.

Step 3: Process your Inbox daily

The Inbox folder is a capture buffer, not storage. Once a day (or whenever it gets noisy), process it:

• Move notes to the right folder
• Add tags
• Delete notes that turned out to be useless
• Expand notes that became important

This takes 5–10 minutes and keeps the system clean without constant discipline.

Step 4: Use version history as a time machine

Krokanti Notes saves every version of every note automatically. This makes long-lived reference notes much more powerful.

Your "Book notes — Atomic Habits" note might evolve over months as you re-read passages and connect ideas. Version history lets you see how your understanding of the book has developed.

Why Krokanti Notes works for a second brain

The tools you read about most often — Notion, Obsidian, Roam Research — are powerful. They're also heavy.

Krokanti Notes wins for personal knowledge management because:

1. Capture speed — opens in under a second, even on mobile
2. Search — instant full-text search across every note
3. Low friction — no databases to configure, no sync setup
4. Permanence — your notes stay yours, exportable, no proprietary format
5. Sharing — any note can become a public page with one toggle

The best second brain isn't the most powerful one — it's the one that captures faithfully and retrieves reliably. Krokanti Notes does both.

FAQ

How is a second brain different from just taking notes? A second brain is intentional — you have a consistent capture habit, a simple organizational structure, and a review practice. Just taking notes is reactive. A second brain is proactive.

Do I need a complex tagging system? No. Start with 5–10 tags and add more only when you notice a recurring pattern. More tags = more maintenance. Less is usually better.

What about bidirectional links like Obsidian has? Bidirectional links are powerful for research and academic writing. For most professionals, they add complexity without proportional value. Manual linking (writing See also: [note title] at the bottom of a note) works 80% as well with 5% of the setup.

How many notes should I expect to have? A healthy second brain after a year of consistent use typically has 200–500 notes. If you have 5,000 notes and can't find anything, your system needs simplification, not more notes.
