Draw, organize, and create with AI. Drawing Studio brings draw.io, Excalidraw, and Mermaid editing together with AI diagram generation and editing. Sketch by hand, build structured diagrams, or write diagrams as code. Use a prompt to create a diagram or a conversation to update an existing one. Keep your documents organized with folders, version history, and iCloud sync. THREE EDITORS, ONE DOCUMENT WORKSPACE • Excalidraw: hand-drawn-style sketches, whiteboards, and visual notes with shapes, text, and arrows. • draw.io: structured diagrams for systems, processes, UML, and technical documentation. • Mermaid: diagrams as code, including flowcharts, sequence diagrams, class diagrams, and Gantt charts. Drawing and editing do not require AI setup. Work directly in the editor, create with AI, or combine both approaches in the same document. FROM A PROMPT TO AN EDITABLE DIAGRAM Ask for a first draft instead of starting from a blank canvas: • "Create a flowchart for an order, from payment to delivery." • "Draw a sequence diagram for a user signing in." • "Make a mind map for planning a product launch." Keep working on the same drawing. Ask AI to add an exception path, rename steps, or reorganize a section. The assistant can read and update the current document, so the result is an editable diagram, not just an image or a reply to copy elsewhere. KEEP YOUR WORK ORGANIZED • Group drawings into folders by project or topic. • Revisit earlier versions with document history. • Keep AI conversations associated with each drawing. • Sync your work across iPhone, iPad, and Mac with iCloud. • Export diagrams as PNG or SVG to share with others. BUILT FOR IDEAS THAT NEED EXPLAINING Map a business process, explain a software architecture, plan a project, or turn study notes into a visual outline. Move from a rough draft to a diagram you can refine and reuse. CHOOSE YOUR AI MODEL AI use requires a configured, compatible model; availability and results depend on the model and provider. Third-party services may require an account and charge for usage separately. YOUR DOCUMENTS AND AI REQUESTS Documents are stored locally and can sync through iCloud. When you use a cloud AI provider, your prompts and document content needed for the task are sent to that provider for processing. Its terms and privacy policy apply. Review generated diagrams before relying on or sharing them.
