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.

Twenty 2.0 is a major release of the open-source CRM that aims to replace Salesforce for developer-first teams. The 2.0 update ships a full SDK, custom data modeling via code, built-in AI agents, serverless functions, and enhanced self-hosting support — positioning it as infrastructure you extend rather than a SaaS box you're locked into. Unlike traditional CRMs where AI is a bolt-on copilot, Twenty embeds AI agents as first-class objects in the data model. Teams can write serverless functions that trigger on CRM events, extending pipelines with custom logic or connecting external AI services. The open data model means you can add fields, relations, and triggers without vendor approval. With over 1,500 Product Hunt followers and a strong GitHub presence, Twenty 2.0 arrives at a moment when companies are actively reconsidering whether to rebuild sales tooling on AI-first foundations or continue paying Salesforce for legacy infrastructure.
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 SDK + serverless functions combo is the right architecture. You get a real CRM out of the box but you can wire in your own AI agents for deal scoring, contact enrichment, or outreach automation without fighting vendor abstractions. This is how CRM should work.”
“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.”
“Salesforce has 25 years of integrations, compliance certifications, and enterprise support. Twenty is exciting for devs but any enterprise evaluating it will immediately ask about SOC 2, GDPR tooling, and migration paths from Salesforce. Those answers aren't there yet.”
“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 CRM is just the first vertical. Once you have an open, AI-extensible data layer for customer relationships, you can build anything on top — automated pipeline management, AI SDRs, deal intelligence. Twenty is betting on the right abstraction.”
“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 small creative agencies or studios managing client relationships, this replaces both a CRM and a project management tool. Self-hosting means your client data stays yours, which is increasingly important for creative professionals.”
