Obsidian vs Logseq: Which Knowledge Graph Wins for PKM?
Category: Reviews · Stage: Decision
By Chaos Content Team
Obsidian and Logseq are both local-first, markdown-based knowledge management tools with graph views. Both have passionate communities. Both promise networked thought.
The fundamental difference: page-based thinking vs. block-based thinking.
After 60 days building knowledge bases in each (30 days per tool), here's which philosophy wins for different types of thinkers.
The Philosophical Split
Obsidian: Page-centric. Each note is a document. Links connect documents to documents.
Logseq: Block-centric. Everything is a bullet point (block). Links connect blocks to blocks.
Why this matters: It changes how you think, capture, and retrieve information.
What Is Logseq's Block-Based Approach?
Every piece of information is a block (bullet point).
Example Logseq daily note:
- Meeting with Sarah about marketing project
- Budget: £15,000
- Timeline: 6 weeks
- [[Project/Marketing-Q4]]
- TODO Follow up on budget approval
- Idea: [[PKM]] systems should prioritize retrieval over capture
- Most people over-organize and under-review
- Related: [[Productivity/Second-Brain]]
Each bullet is a block. Each block can be:
- Referenced individually
- Linked to from other blocks
- Tagged and queried
- Embedded elsewhere
Philosophy: Capture atomically. Connect later. Don't pre-organize into pages.
What Is Obsidian's Page-Based Approach?
Notes are documents. Links connect documents.
Example Obsidian notes:
# Meeting - Sarah - Marketing Project
Date: 2025-08-12
Project: [[Marketing Q4 Campaign]]
## Discussion Points
- Budget approved: £15,000
- Timeline: 6 weeks starting Monday
- Need to coordinate with [[Sarah Thompson]]
## Next Steps
- [ ] Follow up on budget approval
- [ ] Schedule kickoff meeting

# PKM Systems Should Prioritize Retrieval
Most knowledge management systems optimize for capture and organization.
The real bottleneck: retrieval. Getting information back out when you need it.

- [[Productivity Systems]]
Philosophy: Think in documents. Create pages for concepts. Link pages together.
Testing Methodology: 60 Days
Built two knowledge bases with identical content:
- Content: 120 notes about productivity, technology, project notes, meeting logs, personal thoughts
- Time period: 30 days actively using each tool
- Workflow: Captured daily notes, organized knowledge, retrieved information for real projects
Metrics tracked:
- Time to capture new information
- Time to organize/connect information
- Time to retrieve specific information
- Graph structure and usefulness
- Learning curve and frustration
Logseq (Days 1-30)
Week 1: Confusing but Intriguing
Coming from traditional note-taking, block-based thinking felt odd.
"Why is everything a bullet point? Where are my documents?"
But something clicked in Week 2.
Week 2-4: The Block-Based Breakthrough
Realized I was thinking differently. Instead of "what page does this belong in?" I just captured blocks and tagged them.
Example: Captured insight about productivity during meeting notes. Tagged [[Productivity]]. Done.
Later, searching for [[Productivity]] showed all related blocks from meetings, projects, and dedicated notes. Didn't need to file the insight—it connected automatically.
Results:
- Capture time: Very fast (2-3 seconds per thought)
- Organization time: Minimal (tags handle most of it)
- Retrieval: Good (queries are powerful)
- Frustration: Medium (learning curve for queries)
What worked:
- Daily notes became central hub
- Block references created automatic connections
- Queries surfaced related information
- No "where should I put this?" decisions
What didn't:
- Long-form writing felt awkward (everything is bullets)
- Graph view less useful (too many block connections)
- Mobile app inferior to Obsidian's
- Plugin ecosystem smaller
Logseq's Best Features
1. Block References
Reference any block from anywhere.
Example: Meeting note includes block about budget. Reference that exact block in project planning note. When budget changes, it updates everywhere.
2. Powerful Queries
Find blocks matching criteria.
Example query: "Show all TODO blocks tagged #project-x that are not completed"
Logseq automatically generates list from across all notes.
3. No Organization Anxiety
Just capture. Tags and queries handle retrieval.
Obsidian (Days 31-60)
Week 1: Immediately Familiar
Page-based notes felt natural. Create document, write, link to related documents.
No learning curve. If you've used any note app, you understand Obsidian.
Week 2-4: The Organization Challenge
With 120 notes, organization became critical.
Question: What structure? Folders by topic? Tags? MOCs (Maps of Content)?
Spent hours organizing. Created folder structure. Then restructured. Then abandoned folders for tags and MOCs.
The Obsidian paradox: Flexibility is powerful but overwhelming. You can organize however you want, so you spend time deciding how to organize.
Results:
- Capture time: Fast (5-10 seconds per note)
- Organization time: High (30+ min/week structuring)
- Retrieval: Excellent (once organized)
- Frustration: Low (familiar, polished UX)
What worked:
- Long-form writing is natural
- Graph view beautiful and useful (document connections make sense)
- Plugin ecosystem massive (1,000+ plugins)
- Mobile app excellent
- Canvas feature great for visual thinking
What didn't:
- Organization overhead
- Easy to over-organize and under-use
- Atomic note philosophy conflicts with page-based structure
Obsidian's Best Features
1. Massive Plugin Ecosystem
1,000+ community plugins.
Examples:
- Dataview (query notes like database)
- Kanban boards
- Calendar view
- Advanced tables
- PDF annotation
- Spaced repetition
Whatever workflow you imagine, there's probably a plugin.
2. Canvas for Visual Thinking
Spatial arrangement of notes and ideas.
Great for:
- Project planning
- Concept mapping
- Visual brainstorming
3. Beautiful Graph View
Obsidian's graph actually looks good and provides insights about note connections.
Logseq's graph is functional but overwhelming (block-level granularity creates visual noise).

Which Thinking Style Wins?
Block-based (Logseq) excels for:
1. Rapid capture and connection Don't think about structure. Just capture, tag, query later.
2. Atomic note-taking If you naturally think in small, discrete thoughts rather than essays.
3. Daily note workflows Logseq's daily notes are its strength. Everything starts there.
4. Research and synthesis Collecting snippets from various sources, then querying to synthesize.
Page-based (Obsidian) excels for:
1. Long-form thinking and writing Essays, project documentation, detailed analysis.
2. Traditional organization If you prefer folder structures or clear hierarchies.
3. Visual thinkers Canvas and beautiful graph view support spatial thinking.
4. Power users wanting customization Plugin ecosystem enables almost anything.
Use Case Recommendations
Choose Logseq if:
- You want minimal organization overhead
- You think in small, connected insights
- Daily notes are your primary workflow
- You do research requiring synthesis across sources
- You're comfortable with bullet-based thinking
- You want powerful native queries
Choose Obsidian if:
- You write long-form content
- You prefer traditional note organization
- You want extensive customization via plugins
- You're visual thinker who uses graph views
- You need excellent mobile experience
- You want polished, familiar interface
Choose both if:
- You're knowledge management enthusiast experimenting with approaches
- You use Logseq for quick capture, Obsidian for long-form synthesis
- You export Logseq's markdown to Obsidian for writing
- You're researcher who benefits from both paradigms
Choose neither if:
- You have simple note needs (<50 notes total)
- You're satisfied with Apple Notes or Notion
- You don't want local-first complexity
- You prefer guided structure over flexibility
My Personal Verdict After 60 Days
Started as Obsidian advocate. Became Logseq convert—with caveats.
Why Logseq won me over:
The block-based approach actually changed how I think. Stopped agonizing about "where does this note belong?" and just captured thoughts with tags.
Queries are genuinely powerful for retrieving information across disparate notes.
But Obsidian is better for:
Long-form writing. When I need to write an essay or detailed documentation, Obsidian's page-based approach is superior.
Polish and mobile experience.
My hybrid solution:
Daily capture and knowledge connection in Logseq. Long-form writing in Obsidian. Both read the same markdown files in the same folder.
Forces me to get benefits of both approaches.
Key Takeaways
Obsidian and Logseq both offer markdown-based, local-first knowledge management with graph views—but fundamental philosophies differ. Obsidian is page-centric (notes are documents). Logseq is block-centric (everything is connected bullet points).
Block-based thinking (Logseq) reduces organization overhead. No decisions about "where does this belong?"—just capture with tags, retrieve with queries. Powerful for rapid capture and cross-note synthesis.
Page-based thinking (Obsidian) better for long-form work. Essays, documentation, detailed analysis feel natural. Beautiful graph view and massive plugin ecosystem (1,000+ plugins) enable extensive customization.
Learning curves differ significantly. Obsidian feels immediately familiar (it's just notes and links). Logseq requires 1-2 weeks understanding block-based paradigm—but payoff is worth it for daily note workflows.
Mobile and polish favor Obsidian. Obsidian's mobile app is excellent. Graph view is beautiful. UI is polished. Logseq is functional but less refined.
Both are free with local-first data ownership. Obsidian charges $10/month for official sync (or DIY with Dropbox/Git). Logseq sync is free via Git/cloud storage. Both store markdown files you own forever.
