  • Obsidian 2.0がCanvasを中核機能に格上げ。

  • Heptabaseに迫る視覚的な情報整理が可能に。

Slide 1 of 3Remaining 2

While Notion and Loop fight for the corporate cloud, a quiet revolution is happening on our local hard drives. Obsidian and Logseq continue to prove that you dont need a subscription to build a Second Brain.

In 2026, both tools have matured significantly. The choice is no longer about features—its about philosophy .

The File vs The Block

This fundamental difference remains the deciding factor.

  • Obsidian : Focuses on Pages (Documents). You write essays, articles, and long notes.
  • Logseq : Focuses on Blocks (Bullet points). You jot down thoughts”, “tasks, and daily logs.

2026 Updates: What Changed?

Obsidian 2.0: Visual First

Obsidians Canvas is now deeply integrated. You can embed a Canvas inside a note, or a note inside a Canvas. It has effectively killed Heptabase and Scrintal for many users. The Graph View is now interactive and useful, not just a pretty screensaver.

Logseq DB: Speed Demon

The rewritten database backend means Logseq no longer chokes on large graphs. Opening a graph with 20, 000 pages takes less than a second. It feels instantaneous.

Comparison Table

Thinking Style Gardener (Top-down) Architect (Bottom-up)
Mobile App ◎ (Fast, polished) ○ (Getting better)
Sync Paid (Obsidian Sync) Free (Git / iCloud)
AI Privacy Native Local LLM support Native Local LLM support
💡
Why Local LLMs Matter

Both apps now allow you to connect Ollama (running Llama 3 or Mistral) directly. You can “Chat with your notes” without sending a single byte of data to OpenAI. This is the ultimate privacy.

Conclusion

  • If you write content (blogs, books, papers): Obsidian
  • If you manage life (tasks, journals, meeting notes): Logseq

Or, be like me in 2026: Use Obsidian for the permanent library and Logseq for the daily scratchpad. They are just text files, after all. They play nice together.
