Joplin: Markdown Notes with End-to-End Encrypted Sync — Joplin is an offline-first, open source note app that stores notes as Markdown with full-text search, plugin/theme support, and a browser web clipper. It syncs across Windows, macOS, Linux, Android and iOS using end-to-end encryption with Nextcloud, Dropbox, OneDrive or Joplin Cloud, and imports Evernote exports directly.

kepano/obsidian-skills

Agent skills for Obsidian. Teach your agent to use Obsidian CLI and open formats including Markdown, Bases, JSON Canvas.

PDFMathTranslate/PDFMathTranslate

Bilingual PDF translation for scientific papers, formulas and all — Officially presented as an EMNLP 2025 demo, this tool translates scientific PDFs while preserving layout, math, charts and references. It supports Google, DeepL, Ollama and OpenAI backends, with CLI, GUI, Docker, Zotero and MCP integrations for researchers reading papers across languages.

khoj-ai/khoj

Your AI second brain. Self-hostable. Get answers from the web or your docs. Build custom agents, schedule automations, do deep research. Turn any online or local LLM into your personal, autonomous AI (gpt, claude, gemini, llama, qwen, mistral). Get started - free.

handsomestWei/patent-disclosure-skill

A skill toolkit for drafting and decoding Chinese patents — Built for engineers who never get credit as inventors, this skill mines patentable points from project materials and drafts invention/utility/design disclosures with diagrams and editable Word output. It also turns dense patent texts into plain-language notes stored in Obsidian, building a searchable personal patent knowledge base over time.

backnotprop/plannotator

A visual annotation layer for reviewing coding agent plans — Plannotator lets you markup and review agent-generated plans, markdown specs, HTML artifacts, and code diffs before implementation, then send comments straight back to the agent. It works across many CLI agents including Claude Code, Codex, Amp, Gemini CLI, and OpenCode, making it useful for teams coordinating multiple AI coding tools.

breferrari/obsidian-mind

An Obsidian vault that gives coding agents a working memory — Obsidian Mind turns an Obsidian vault into persistent memory for AI coding agents, so sessions build on past decisions instead of starting from zero. It works with Claude Code (full support), plus Codex CLI and Gemini CLI, using shared hooks and commands like /om-standup and /om-dump.

eugeniughelbur/obsidian-second-brain

Shared markdown memory lets 8 AI coding agents work from one Obsidian vault — This project stores persistent memory as plain markdown in Obsidian so Claude Code, Codex, Gemini, Cursor, Grok Bot and others share one brain instead of starting fresh each session. Its new Crew feature adds a shared logbook so different agents can see what each other already did. 48 commands cover semantic search, self-rewriting notes and key-less research, useful for anyone running multiple AI coding tools against the same project.

atomicstrata/llm-wiki-compiler

A CLI compiler that turns raw sources into an interlinked wiki — llmwiki compiles raw documents into an interlinked, Obsidian-friendly wiki using LLMs. Version 1.5 decouples wiki behavior from storage, adds bearer-authenticated Converse gateways, removes the fixed concept page limit, and gives the live viewer auto-refresh after compiles. Useful for anyone building and maintaining a growing knowledge base from scattered source material.

obsidianmd/obsidian-help

Obsidian's Help Docs, Written as Vaults in 30+ Languages — This is the actual source of Obsidian's official help site, structured as standalone Obsidian vaults per language and published via Obsidian Publish. It's useful for contributors fixing docs, translators localizing content, or anyone curious how Obsidian documents its own features like Bases using its own tool.

byenzyme/enzyme

A local semantic index that lets coding agents cite your notes — Enzyme builds a local-first index of existing Markdown notes (folders, tags, links, dates) so agents like Claude Code or Codex can retrieve and cite related notes without sending everything to a frontier model. It claims 350x lower cost and 1000x faster search, targeting PKM/Obsidian users who want agent-aware semantic search over their own vault.
