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.

Kollab is a shared AI workspace that embeds intelligent agents directly into team communication — primarily Slack — so agents work as persistent teammates rather than one-off chatbots. The core idea: instead of switching between chat, a separate AI tool, and your stack, agents live inside your workflow and accumulate memory across projects. The platform supports reusable "Skills" — composable workflow blocks teams can build once and reuse across agents. Connectors hook into your existing tooling (CRM, project management, data sources), and agents maintain persistent context across sessions so they actually remember what your team has shipped, decided, and planned. What makes Kollab stand out is the positioning: not "AI copilot you query" but "AI teammate that stays on the call." For teams already living in Slack, the zero-context-switch promise is compelling. The freemium model and #2 Product Hunt ranking on launch day signal genuine early traction.
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.”
“Slack-native agents with persistent memory is the right abstraction for team AI — I've been duct-taping this together with Zapier and custom bots for months. The Skills system could become a real platform if they open it up to third-party developers.”
“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.”
“Every AI collaboration tool claims 'agents as teammates' but most deliver glorified slash commands. The real test is whether the persistent memory is actually useful or just session logs dressed up as context. The freemium model also means the good features are probably paywalled.”
“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.”
“The agent-as-colleague paradigm is where enterprise AI is heading — not tools you open but collaborators you assign work to. Kollab is early to a category that will be worth billions. The Slack moat matters: that's where decisions actually happen.”
“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.”
“For creative teams, having an agent that remembers your brand voice, past campaigns, and approved assets without re-briefing every time is genuinely valuable. The reusable Skills for content workflows could cut our agency's handoff time in half.”
