Khoj is developed as a self-hostable personal AI and "second brain." It combines local or cloud language models with web retrieval, personal documents, semantic search, custom agents, automations, and an experimental /research mode.

This is a decision page. Claude Code wrote it after reading a project's notes, and it shows the detail a chat question leaves out. I answer it in Obsidian.

quartz
🌱 a fast, batteries-included static-site generator that transforms Markdown content into fully functional websites
Project mention: The problem is not the AI code, but nobody knows anything anymore | news.ycombinator.com | 2026-09-28This page has been live long before AI appeared, I used Quartz [1] v3, now at v5. But added some features I like with AI, yes, but still keeping my beloved color theme and web style as I had it for a long, long time. The whole code for the second brain (ssp.sh/brain/*) is on GitHub, in case you want to check it [2], but you can also see the "Changelog" in the footer to see recent visual changes. But I'd be curious what makes you think it's AI-generated?

obsidian-smart-connections
Find related notes and excerpts while writing. Your link building copilot displays relevant content in graph + list view. A local embedding model powers semantic search. Zero setup. No API key.
SmartConnections but heads up, Connections Pro asks $300/year, or, more for the plugin than for an LLM subscription, more than Microsoft Office for that matter.

I use the Minimal theme with its companion settings plugin. The name is accurate. It strips back the visual chrome, improves typography, and keeps the focus on the content. I've turned off most of the optional visual styles and left it close to its defaults.
-
obsidian-clipper
Highlight and capture the web in your favorite browser. The official Web Clipper extension for Obsidian.
Project mention: Ask HN: Any solution for bookmarks on various services? | news.ycombinator.com | 2026-10-09That is partially what I do! I don't favourite stuff at all really on HN/X/whatever. I use https://obsidian.md/clipper to download them straight into my vault.
Then there is https://pi.dev/packages/pi-obsidian which I use to give an agent access to my vault for searching/organising tasks

obsidian-second-brain
Persistent memory for Claude Code and 6 other CLI agents, stored as plain markdown in your Obsidian vault. Stop re-explaining your projects, decisions and people every session. 45 commands: hybrid semantic search, self-rewriting notes, key-less web research, and scheduled agents that maintain the vault while you sleep.
Project mention: A Vault That Rewrites Itself: obsidian-second-brain and the Karpathy LLM Wiki Pattern | dev.to | 2026-10-08Two tools most of us own ignore each other completely. An Obsidian vault with hundreds of notes nobody rereads. An AI agent in the terminal whose every session starts from zero, as if the past never happened. The obsidian-second-brain repository glues them together: 4.7k stars, MIT, authored by Eugeniu Ghelbur. The README's own formula: an evolution of Karpathy's LLM Wiki pattern, a vault that rewrites itself. Here's a review, plus why I read the whole thing with deja vu: my business CRM runs on the same pattern.

obsidian-sample-plugin
Template for Obsidian community plugins with build configuration and development best practices.

basic-memory
AI conversations that actually remember. Never re-explain your project to your AI again. Join our Discord: https://discord.gg/tyvKNccgqN
Project mention: Best MCP Memory Servers for Teams in 2026: Context Cloud vs mem0 vs Basic Memory vs claude-mem vs MemPalace | dev.to | 2026-05-28Basic Memory is the simplest option and that's its strength. It stores knowledge as markdown files that you can read, edit, and version control yourself. No database, no cloud, no dependencies beyond the CLI.
-
llm-wiki-agent
A personal knowledge base that builds and maintains itself. Drop in sources — Claude (or Codex/Gemini) reads them, extracts knowledge, and maintains a persistent interlinked wiki. Works with Claude Code, Codex, OpenCode, Gemini CLI. No API key needed.
Project mention: Show HN: Claude Soul – cross-session learning engine for Claude Code | news.ycombinator.com | 2026-05-18I'm really interested in trying this out. Currently, I'm using the standard Obsidian MD format for long-term memory (https://github.com/SamurAIGPT/llm-wiki-agent) and asking the agent to access the wiki at the start of the task and then record useful information at the end

Project mention: Show HN: NoteDiscovery – Free Self-Hosted Alternative to Notion/Obsidian | news.ycombinator.com | 2025-11-11
GitHub: https://github.com/gamosoft/NoteDiscovery
Please bear in mind it's in VERY early stages so it doesn't get even close to what the excellent Obsidian can do, but for the time being it's more than enough to suit my personal needs, so depending on my availability I may be adding more features. ;-)
I really hope you like it!
-
obsidian-spaced-repetition
Fight the forgetting curve by reviewing flashcards & entire notes on Obsidian
Project mention: Turning YouTube Videos Into Obsidian Notes — and What Shipping the Plugin Taught Me | dev.to | 2026-09-13Plus a right-sidebar chat panel scoped to the note you're reading, and a command that turns the quiz into Spaced Repetition cards.
-
obsidian-latex-suite
Make typesetting LaTeX as fast as handwriting through snippets, text expansion, and editor enhancements
Project mention: obsidian-latex-suite VS latex-autofill - a user suggested alternative | libhunt.com/r/obsidian-latex-suite | 2026-09-29 -
obsidian-style-settings
A dynamic user interface for adjusting theme, plugin, and snippet CSS variables within Obsidian
-
-
GitSync
Mobile Git client for syncing a repository between remote and a local directory (by ViscousPot)
> Or a dedicated app like GitSync
Which gates "sync" behind an expensive "premium" paywall.
It feels criminal to charge that much for the sync feature when it also can't possibly work, iOS actively does not want apps to run in the background, and does not offer a viable method for this libgit wrapper to execute libgit on, for example, a filesystem inotify event or write or whatever.
https://github.com/ViscousPot/GitSync/issues/807#issuecommen...
What do you know, people are observing it doesn't really work.
> Apple's iOS has a pluggable Files system.
Okay, excellent, maybe you can tell me how to do this.
I have opened the builtin iOS notes app. It by default can sync notes with iCloud. I would like to have it store my notes in Git or Dropbox or anything else, and be able to also edit them on another machine and have the changes sync.
I won't hold my breath on how to do this because like clearly things are not pluggable, the builtin iOS apps don't work with anything but iCloud and the filesystem is obviously not pluggable or generic.
