Project Overview
AI Canvas is an innovative Obsidian plugin that brings the power of large language models directly into your knowledge management workflow. Built for the growing community of AI-assisted knowledge workers, this plugin transforms Obsidian from a note-taking app into an AI-powered 2D canvas workspace.
