Your brain is for thinking, not storage. A “second brain” is external—capturing, organizing, retrieving knowledge.
Tiago Forte’s methodology works. You don’t need paid software. Here’s a complete free system.
The CODE Method
Forte breaks knowledge work into four phases:
- Capture — Save ideas, quotes, insights
- Organize — Structure what you captured
- Distill — Extract key insights
- Express — Use knowledge to create
Your tools need to support all four.
Free Tool Stack
Capture: Readwise Reader + Apple Notes/Google Keep

Cost: Free unlimited pages
Express: Your existing tools
Writing: Google Docs, Notion, Obsidian Presentations: Google Slides, Canva Video: Your editor Code: Your IDE
Your second brain feeds tools you already use.
PARA System Setup
Forte’s PARA organizes into four categories:
- Projects — Active work with deadlines
- Areas — Ongoing responsibilities
- Resources — Reference material
- Archives — Completed/inactive items
In Obsidian
Create folders:
📁 01 Projects/
📁 02 Areas/
📁 03 Resources/
📁 04 Archives/
Projects: Own notes with outcomes, deadlines. Link to resources and areas.
Areas: Evergreen notes—health, finances, relationships, professional development.
Resources: Book summaries, article highlights, research.
Archives: Completed projects, inactive resources. Searchable when needed.
In Notion
Create database “Second Brain Dashboard”:
Active Projects View: Current projects with due dates This Week’s Learning: Recent captures and highlights Resource Library: Searchable by topic Weekly Review: Template for processing
Daily Workflow
Consistency matters more than setup.
Morning: Review (10 min)
- Check Obsidian #inbox
- Review yesterday’s Readwise highlights
- Pick one insight to develop
Day: Capture (2 min each)
- Article → Readwise Reader
- Thought → Apple Notes/Google Keep
- Meeting notes → Obsidian daily note
- Book highlight → Readwise
Don’t organize while capturing. Speed matters. Dump to inbox, process later.
Evening: Process (15 min)
- Move captures to PARA folders
- Create bi-directional links
- Write 2-3 sentences distilling insights
- Update project notes
Weekly: Review & Distill (1 hour)
- Review week’s captures
- Move completed items to archives
- Update project statuses
- Write weekly summary in Notion
- Identify themes and connections
Advanced Techniques
Progressive Summarization
Don’t save everything equally. Five layers:
- Layer 1: Raw capture
- Layer 2: Bold key passages
- Layer 3: Highlight best bolded parts
- Layer 4: Summarize in your words
- Layer 5: Remix into creations
Layer 1 at capture. Layers 2-3 at weekly review. Layers 4-5 when using knowledge.
Zettelkasten Method
Combine PARA with Zettelkasten:
- Fleeting notes: Quick captures (Apple Notes)
- Literature notes: Summarized sources (Obsidian Resources)
- Permanent notes: Your insights (Obsidian Areas)
- Project notes: Active work (Obsidian Projects)
Permanent notes stand alone and connect through links.
Spaced Repetition
Anki (free) or RemNote (free tier) for long-term retention. Core concepts, frameworks, vocabulary.
Export Readwise highlights to Anki.
Pitfalls to Avoid
Perfectionism: Start messy. Improve gradually.
Over-capturing: Save less. If you won’t use it in 6 months, skip it.
Under-processing: Capturing without distilling creates a landfill. Schedule review time.
Tool hopping: Commit to your stack for 3 months. Switching destroys momentum.
Ignoring search: Messy system you can search beats perfect system you can’t navigate. Obsidian’s search works—use it.
Migration from Paid Tools
Notion → Obsidian: Export markdown, import. ~1 hour for 500 notes.
Roam → Obsidian: Export JSON, use community converter. Links transfer.
Evernote → Obsidian: Export ENEX, use Yarle converter. Some formatting loss.
Readwise → Omnivore: Similar highlight handling. 10 minute export/import.
Summary
Second brain doesn’t require expensive software. Free tools work:
- Readwise/Omnivore for capture
- Obsidian for organization
- Notion for dashboards
- Existing tools for creation
Methodology matters more than tools. Consistent capture. Regular review. Active use.
Start today. Capture one thing. Link it. Repeat.
