Claudian is an Obsidian plugin that embeds Claude Code directly into your knowledge vault — not as a chat sidebar, but as a full agent capable of reading, creating, editing, and linking notes with tool use and multi-step reasoning. It's the first plugin to bring genuine agent capabilities to Obsidian rather than wrapping a chat API. Once installed, Claudian can scan your vault for related notes, synthesize information across documents, create new notes with proper backlinks, and run user-defined workflows as repeatable commands. It understands Obsidian-specific constructs like frontmatter, tags, dataview queries, and the graph — treating your vault as a structured knowledge base rather than a folder of text files. The plugin is open source and was built by a solo developer experimenting with Obsidian's plugin API and Claude's tool-use capabilities. It's gaining traction fast in the PKM and second-brain communities, where the idea of a genuinely capable AI collaborator embedded in a private, offline-first knowledge base is a compelling alternative to cloud-native tools.

Travel Hacking Toolkit is an MCP-based skills layer that teaches AI assistants how to search award flights, compare loyalty program valuations, and surface hotel points deals in natural language. Built by Michael Borohovski and posted as a Show HN, it connects Claude Code and OpenCode to live travel APIs including Seats.aero, SerpAPI, Duffel, and AwardWallet through structured markdown "skills" files that teach the AI how to call each service. The toolkit includes MCP servers for Skiplagged, Kiwi.com, Trivago, Ferryhopper, and Airbnb, enabling queries like "find me a 60,000-mile business class flight to Tokyo and compare it to cash prices." Static data files encode airline alliance structures, hotel chain partner awards, historical sweet spots, and community-sourced valuations—giving the AI grounded knowledge rather than hallucinated redemption values. The project is deliberately low-abstraction: skills are readable markdown files you can edit to add new programs or APIs, and it requires no persistent backend. With 205 stars from a Show HN debut, it's a small but focused tool for the travel hacking community that finally gives the "ask your AI for deals" fantasy some real API teeth.
Reviewer scorecard
“Giving Claude Code actual read-write access to an Obsidian vault — not just chat context — is the right model. The ability to run multi-step workflows that create linked notes and run dataview queries puts this well ahead of any chat plugin.”
“The MCP architecture is exactly right for this problem—travel APIs are diverse and constantly changing, and skills-as-markdown-files means any developer can add a new loyalty program or airline API in 30 minutes without touching a codebase. The Seats.aero integration alone makes this worth setting up.”
“An agent with write access to your personal knowledge base is a trust cliff. A hallucinated backlink or an overwritten note could quietly corrupt months of organized thinking. The vault backup discipline required to use this safely isn't mentioned in the README.”
“Most of these APIs require paid keys or have aggressive rate limits, and the 'sweet spots' data will go stale quickly as airlines devalue programs. This solves a real problem but requires significant manual maintenance to stay useful—you're essentially signing up to maintain your own travel hacking research infrastructure.”
“Obsidian's graph is one of the few personal knowledge structures rich enough to give an AI agent meaningful context. Claudian points at a future where your second brain and your AI collaborator are genuinely the same system, not two tools awkwardly integrated.”
“This is an early template for domain-specific MCP skill sets—curated API knowledge plus structured data that turns a general AI assistant into a specialist. As MCP adoption grows, we'll see these skill bundles for every vertical from legal research to healthcare, and travel hacking is a natural first mover.”
“For writers and researchers who already live in Obsidian, this is the most exciting release in months. Ask it to synthesize three interview notes into a first-draft outline, with backlinks intact — that alone pays for the setup time.”
“Finally something that makes the 'just ask your AI to book travel' promise real rather than theoretical. The alliance and partner award data files are the kind of curated, hard-to-find knowledge that normally lives in obscure blog posts—having it structured for AI consumption is genuinely useful.”
