Brain fog, but make it clickable
Show HN: Skill for your agent to visualize your gbrain and Obsidian
Your notes can now become a glowing mind map — and the comments are split on whether that’s genius or just pretty chaos
TLDR: This project turns ordinary note folders into an interactive visual map you can explore in a web browser. Commenters instantly split between “looks cool, but is it actually useful?” and “wait, I want this for my own project,” which is exactly why people are paying attention.
A new Show HN post is promising to turn your pile of personal notes into a clickable, animated “brain map” you can open in a browser. In plain English: instead of scrolling through endless text files, you get a colorful web of ideas, plus a timeline that lets you watch your knowledge grow over time. It works with note folders from apps like Obsidian, and the pitch is very much “open it in seconds, no drama, no setup meltdown.”
But of course, the real fun started in the reactions. One camp immediately went full skeptical: what are these maps actually for? User purpleflashing basically voiced the question lurking in many readers’ heads, asking whether this kind of visual note galaxy really helps anyone find things faster — or if it’s just digital wallpaper for productivity fans. That’s the hottest low-key debate here: useful tool or beautiful procrastination machine?
Meanwhile, another commenter came in with classic builder energy instead of snark, saying they’d wanted something like this for their own wiki project, Nexidion, and were already thinking about combining the two. That gave the thread a very Hacker News twist: half side-eye, half “brb, forking this next week.” The accidental comedy is that even the doubters sound curious. Everyone’s acting cool, but the vibe is clear: people may not agree on the purpose, yet they absolutely want to click the shiny brain web.
Key Points
- •brain-map converts Markdown note folders, including Obsidian vaults and gbrain exports, into a self-contained interactive HTML knowledge map.
- •The repository ships with a zero-setup demo containing 992 fictional notes across work, study, and life themes.
- •The builder reads plain Markdown with YAML frontmatter and `[[wikilinks]]`, and maps folders, tags, links, and timestamps into graph structure and timeline data.
- •Optional dependencies (`networkx`, `numpy`, `scipy`) allow precomputed layouts, while the standard-library-only path computes layout in the browser using Cytoscape cose.
- •The generated HTML supports timeline playback, theme and type filters, search, node inspection, neighborhood highlighting, and responsive display on phones.
