Drawing Studio vs MDreaderlite

Drawing Studio is a cross-platform visual note-taking tool for Apple users, built for knowledge management — now with a built-in AI assistant. Sketch freely with Excalidraw, write diagrams as code with Mermaid, and build professional visuals with draw.io — then let AI generate and edit them for you, right on the canvas. Organize with folders, revisit with version history, and sync everything seamlessly via iCloud. AI Assistant (New) • Draw with words – Describe what you want and AI creates the diagram for you, in Excalidraw, Mermaid, or draw.io • Edits your canvas directly – AI reads your current drawing and updates it in place — refine, extend, restructure, or explain • Every change is safe – AI edits land as version snapshots, so you can roll back anytime • Per-document chat – Each drawing keeps its own conversation history, scoped and searchable • Bring your own model – Connect any compatible provider • Private by design – Your API keys and conversations stay on your device and iCloud — no middleman servers Supported Formats • Excalidraw – Hand-drawn-style diagrams, ideal for sketches, flows, cards, and visual thinking • Mermaid – Code-based diagrams: flowcharts, sequence diagrams, class diagrams, Gantt charts, and more • draw.io – Powerful structured diagrams for technical drawings, wireframes, flowcharts, UML, and more Key Features • AI Assistant – Generate and edit diagrams from natural language, powered by the model you choose • Folders – Organize drawings by project, topic, or domain • Auto Version History – Every change is saved, with easy access to previous versions • iCloud Sync – Works seamlessly across iPhone, iPad, and Mac — no account required • Export – Export to PNG or SVG for sharing Use Cases • Knowledge Management – Build a personal knowledge system (PKM / Zettelkasten) • Project Planning – Create mind maps, timelines, flowcharts to clarify goals • Technical Documentation – Diagram systems and architecture using Mermaid or draw.io • Creative Thinking – Freely sketch ideas, concepts, and presentations • AI Co-drawing – Turn a rough idea into a finished diagram, then refine it in a conversation Privacy First • All data is stored locally and in your iCloud — no external servers • Your AI keys and chats stay on your device — bring your own model • No user tracking, no content collection, no ads • Your data is yours, always
