SketchLab
A browser-based sketching and diagramming app for mapping ideas, architecture, and layered systems on a fast canvas.
Why people use it
SketchLab is a lightweight canvas app for turning ideas into visual structure. It gives you fast shape, text, icon, image, edge, and layer tools, plus an AI-assisted diagram generator for architecture-style boards when you want a starting point instead of a blank canvas.
- Draw shapes, text, icons, images, and connected edges on a freeform canvas
- Use layers and floor-style depth to separate parts of a system
- Generate architecture diagrams from prompts with an OpenAI API key
- Manage multiple boards from the built-in board drawer
- Export board thumbnails and keep diagrams lightweight in the browser
Everything built in
Freeform diagram canvas
Sketch rectangles, circles, icons, labels, images, and text directly on the canvas, then arrange them into a readable system map.
Connected edges
Draw directed or undirected links between nodes so relationships are visible instead of buried in notes.
Layered boards
Use named layers, visibility controls, floor colors, and distant-layer fading to make complex diagrams easier to scan.
AI diagram generation
Prompt SketchLab to generate an editable architecture diagram, then refine the result with the normal drawing tools.
Board drawer
Create, rename, switch, copy, and delete boards without leaving the sketching surface.
Fast browser workflow
Open the app in a browser and start mapping ideas without a heavyweight design suite or account flow.
Common questions
What is SketchLab for?

Does SketchLab support AI generation?
Yes. The app includes an AI panel for generating editable diagram boards from prompts when an OpenAI API key is available.
Is it a design tool or a diagramming tool?
It is closer to a fast diagramming and sketching tool: shapes, edges, text, icons, images, layers, boards, and lightweight export.
