Domvault – self-hostable second brain with consent-based note sharing

Hi HN, wanted to translate this into a more human-readable post - please see below and would love any and all feedback! What is it: A second brain you self-host and engine to compound itself and spark new ideas, from your own ideas. Why: ROI on your own knowledge, actually realize the value from your ideas. Down the line I'd love for this to evolve into a wider / shareable concept -- Haven't fully figured this out yet which is part of the reason I am posting. View the /constellation folder for the specs on that concept. (Self hosting engine is all in the repo as well) Looking…

What it does

An AI-augmented second brain you can self-host. Contribute to dys5315/domvault development by creating an account on GitHub.

Own your notes (plain Markdown, on your machine), let an agent surface the connections between them, and share only what you choose — signed and credited. ▶ See it live — explore my own notes as a zoomable universe, no install needed: https://dys5315.github.io/domvault/constellation/ Domvault is the engine , not the content . You bring your own notes; the repo ships the structure, workflows, scripts, and agent instructions that make a plain folder of Markdown behave like a living, self-improving graph. Source-available (PolyForm Noncommercial) · zero runtime dependencies · honest note: I designed and directed it, but an AI agent wrote most of the code. Most "second brain" templates are just…from github.com

    Hi HN, I'm Dom, a solo founder. I built Second Brain to solve a common issue I had with AI chats: the knowledge disappears. There’s no structure, no memory, and no way to reuse or build on them. So I built a tool that combines AI chat with a visual, interconnected knowledge system. Key features: - Save AI responses into editable docs (Notion-style Pages). - AI Visual board with multiple content & chat nodes (like Miro meets ChatGPT). - Add and chat with YouTubes, TikToks, Audio, PDFs, GitHub repos, Looms, websites, etc. - Organize using Projects and Smart Tags — then chat with full contexts.…

    Hi HN, I've been waiting to post what I've been working on for a few weeks now:) Today we're launching LayerVault, which is a version control system made for designers. The URL is http://www.layervault.com LayerVault keeps track of what you're working on without adding extra steps to your process. The app runs in your toolbar and tracks changes you make to your files. Basically — each time you create or modify a file you’re working on, LayerVault saves a copy. You can then login, flip through its versions, and download a version from a few weeks ago. It's pretty neat — and we’ve built some…

  • Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  • Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
