This Obsidian plugin integrates Claude Code as a sidebar chat panel, empowering academic researchers. It streamlines literature reviews, citation checking, manuscript editing, and peer review directly within their writing environment, offering specialized AI-driven research skills and inline diff editing.

How It Works

KatmerCode embeds Claude Code via its Agent SDK, running as a subprocess managed by the Claude Code CLI. It enhances the Obsidian editor with word-level inline diff tracking for manuscript revisions. A suite of 7 academic "skills" (slash commands) query academic databases (Semantic Scholar, CrossRef, etc.) for structured analysis, generating interactive HTML reports. Integration with local MCP servers is supported for potentially faster API interactions.

Quick Start & Requirements

• Prerequisites: Obsidian 1.4.0+ (desktop), Claude Code CLI installed and logged in (npm install -g @anthropic-ai/claude-code && claude), Claude API access, bash shell.
• Installation: Install CLI, clone repo (git clone https://github.com/hkcanan/katmer-code.git), cd katmer-code, npm install, npm run build. Copy generated files (main.js, manifest.json, styles.css) to <your-vault>/.obsidian/plugins/katmer-code/. Enable plugin in Obsidian and "Allow Web Requests" for academic skills.
