TL;DR

Viczian’s PKM philosophy prioritizes purposeful thinking and link clarification over frictionless capture.

Briefing

Personal knowledge management is shifting from “frictionless capture” to deliberate thinking—using Excalidraw and ExcaliBrain to make notes searchable, relationships explicit, and gaps visible. Zsolt Viczian’s core claim is that the real value isn’t speed or automation; it’s the mental work of turning ideas into structured links and then revisiting them. That approach shows up across his tool choices and his workflow: he builds visual summaries that remain text-based, and he visualizes the structure of his vault as a graph that helps him “garden” knowledge over time.

Viczian’s path into PKM began during COVID, when extra (unpaid) leave pushed him to experiment publicly with ideas. His technical background traces back to a PhD in quality management systems and documentation—experience that later led him to The Brain, which he used for about two decades. He praises The Brain’s visualization as intuitive, but criticizes its closed ecosystem: without a robust plugin marketplace, he couldn’t solve a key need—getting visual notes into a searchable workflow. That limitation drove him to build and integrate Excalidraw into other systems.

Excalidraw itself is open source and developed by a broader team; Viczian contributed by integrating it into Roam Research and later into Obsidian. The switch reflects a practical tradeoff: The Brain’s visualization strength versus Obsidian’s extensibility. He tried Roam first, liking its simple interface, but eventually moved to Obsidian when it better fit his evolving requirements.

Methodologically, his note-taking is anchored in GTD (Getting Things Done) because his work life is dominated by meetings and action tracking. He also uses PKM practices like progressive summarization and “Book on a Page” outputs, while experimenting with Zettelkasten-style linking. Over time, he moved from a daily-note-centric approach toward more structured summaries and deeper synthesis—especially through visual aggregation.

That synthesis is where Excalidraw matters. Viczian emphasizes that typed text inside Excalidraw becomes Markdown, so it stays searchable and linkable inside Obsidian rather than becoming “just a picture.” He demonstrates a “Book on a Page” workflow for summarizing dense books, where clickable links jump from the visual summary into deeper notes. He also previews a forthcoming feature (tied to an upcoming version) that allows linking to a portion of an image—turning sections of a diagram into navigable, embedded references.

ExcaliBrain takes the opposite direction: instead of turning visuals into text, it visualizes the relationships already present in Obsidian notes. It generates a graph from links—forward links, backlinks, and mutual “handshake” relationships—displaying parents, children, and lateral connections. A distinctive feature is that it can surface “uncreated” referenced notes, effectively highlighting knowledge gaps. Viczian uses this to refine his ontology of linking: he tries to add descriptions to links so the relationship meaning is visible in the graph.

The workflow encourages ongoing revision rather than one-time capture. He frames the process as “purposeful friction”: writing down what’s fuzzy, clarifying relationships, and using the graph to challenge assumptions. For learning, he points to his YouTube channel as the most reliable source despite frequent updates, and he recommends core Obsidian plugins like Dataview and Templater as foundational tools for building a system around structured notes.

Cornell Notes

Zsolt Viczian builds a PKM workflow around Excalidraw and ExcaliBrain to make knowledge both navigable and searchable. Excalidraw keeps typed content as Markdown, so visual summaries remain text-based and linkable inside Obsidian. ExcaliBrain then visualizes the relationships in an Obsidian vault—turning forward links into children, backlinks into parents, and mutual links into lateral “friend” connections—while also surfacing references to notes that don’t yet exist. That graph helps him “garden” his vault by clarifying link meaning (ontology) and exposing gaps. The approach emphasizes deliberate thinking over frictionless capture, using purposeful effort to deepen understanding.

Why did Viczian leave The Brain after using it for decades?

He credits The Brain with having the most intuitive visualization, but he says it’s a closed system with limited ecosystem support. Without a strong plugin marketplace, he couldn’t build the missing piece he wanted: a way to bring visual notes into a searchable, extensible workflow. That constraint pushed him toward tools with better integration and extensibility.

What makes Excalidraw different from “just drawing” in a note system?

Text typed inside Excalidraw is converted into Markdown, so it remains searchable and can carry links. This makes Excalidraw feel integrated with Obsidian rather than a separate graphics tool. Viczian uses this for “Book on a Page” summaries where clickable elements lead to deeper notes.

How does ExcaliBrain decide what is a parent, child, or lateral connection?

ExcaliBrain uses link directionality. A forward link from one note to another becomes a child relationship. If a note is referenced by another note (a backlink from the other note’s perspective), it becomes a parent. When two notes reference each other (a mutual handshake), the relationship becomes lateral, shown on the side of the graph.

What’s the practical value of ExcaliBrain showing “uncreated” notes?

When a note is referenced but doesn’t exist as a created page, ExcaliBrain can still display it as a node. Viczian treats that as a signal of a knowledge gap—an invitation to create the missing note or clarify the structure of the vault.

How does Viczian’s workflow balance GTD, PKM, and summarization?

For work, his note-taking is heavily GTD-based: meeting notes and action tracking, plus capturing examples for later performance reviews. For PKM, he increasingly uses progressive summarization and “Book on a Page” outputs to extract deeper understanding from reading, including dense books.

What learning path does he recommend given frequent updates to Excalidraw/ExcaliBrain?

He warns that walkthroughs can become outdated quickly because he continually tinkers with the tools. His YouTube channel is presented as the most reliable place to find up-to-date feature explanations, with titles intended to match specific questions.

Review Questions

  1. How do forward links, backlinks, and mutual links map to ExcaliBrain’s parent/child/lateral layout?
  2. What does it mean that Excalidraw text becomes Markdown, and how does that affect search and linking?
  3. In what ways does Viczian treat “uncreated” referenced notes as evidence of gaps in knowledge?

Key Points

  1. 1

    Viczian’s PKM philosophy prioritizes purposeful thinking and link clarification over frictionless capture.

  2. 2

    The Brain’s visualization was valuable, but its closed ecosystem pushed him toward tools with stronger extensibility.

  3. 3

    Excalidraw’s typed content becomes Markdown, keeping visual summaries searchable and linkable inside Obsidian.

  4. 4

    ExcaliBrain visualizes Obsidian relationships by link direction: forward links become children, backlinks become parents, and mutual links become lateral connections.

  5. 5

    ExcaliBrain can display referenced notes that don’t yet exist, turning them into visible knowledge gaps.

  6. 6

    Viczian’s work note-taking is GTD-centered (meeting notes and action tracking), while PKM work leans on progressive summarization and “Book on a Page” synthesis.

  7. 7

    He recommends his YouTube channel as the best learning source because tool updates can quickly make older walkthroughs stale.

Highlights

Excalidraw diagrams aren’t dead images: typed text is stored as Markdown, so summaries stay searchable and navigable.
ExcaliBrain can surface “uncreated” referenced notes, effectively pointing to missing pieces in a knowledge system.
Viczian frames productivity as the wrong goal; the point of PKM is to think through fuzzy ideas and deepen understanding through effort.
