TikZ Generator
Create TikZ diagrams with AI - simply describe any diagram and get publication-quality TikZ/LaTeX code
Input
Diagram Description
Describe your diagram in natural language
Examples:
Tip: Be specific about positions, colors, and connections. For example: "A red rectangle labeled 'Start' connected by an arrow to a blue circle labeled 'Process'"
Output
TikZ Code
Ready to use in your LaTeX documents
Describe your diagram, click generate, and your TikZ code will appear here.
What is TikZ?
TikZ is a powerful LaTeX package for creating high-quality graphics and diagrams programmatically. It's widely used in academic papers, technical documentation, and presentations for its ability to produce publication-ready vector graphics that integrate seamlessly with LaTeX documents.
Example Diagrams You Can Create
Flowcharts
Process flows, algorithms, decision trees
Graphs & Plots
Mathematical functions, data visualization
Tree Structures
Binary trees, org charts, hierarchies
Network Diagrams
Neural networks, computer networks
Geometric Shapes
Polygons, circles, 3D shapes
Circuit Diagrams
Electrical circuits, logic gates
Timelines
Historical events, project schedules
UML Diagrams
Class diagrams, sequence diagrams
Tips for Best Results
1.
Be specific: Instead of "a tree", say "a binary tree with 7 nodes, root labeled A, with left child B and right child C"
2.
Mention colors: Specify colors for nodes, edges, and backgrounds if you have preferences
3.
Describe connections: Explain how elements connect - arrows, lines, dashed, labeled edges
4.
Specify layout: Mention if elements should be horizontal, vertical, circular, or in a grid
How to generate a TikZ diagram
- 1
Describe the diagram
Write what you want in plain English: the shapes, their labels, how they connect, and the layout, like 'a flowchart with three boxes connected by arrows'.
- 2
Click Generate
The AI writes complete, compilable TikZ code for the diagram, including the tikzpicture environment and any libraries it needs.
- 3
Compile or refine
Preview the result, tweak the description or the code, and paste the final tikzpicture into your document.
What you can draw with it
Flowcharts, trees, graphs, circuit diagrams, block diagrams, geometric figures, coordinate plots, and annotated illustrations: anything TikZ can draw, you can describe. If you already have the diagram as a picture, whiteboard photo, or hand sketch, the Image to TikZ converter recreates it as TikZ code directly instead of starting from a description.
Editing the generated code
The output is standard TikZ, so everything is adjustable: node positions, arrow styles, colors, and spacing. If you want to understand what each command does before changing it, the TikZ guides on flowcharts, arrows, and colors and styles walk through the syntax with worked examples.
Frequently asked questions
Is the TikZ generator free?
Yes. Generating diagrams is free without an account; heavier use is covered by the free trial of the full Underleaf app.
What is TikZ?
TikZ is the standard drawing language for LaTeX. It produces vector diagrams that match your document's fonts and typesetting, which is why journals and theses prefer it over pasted images.
Can I convert an existing image or sketch to TikZ?
Yes. Use the Image to TikZ converter: upload a photo, screenshot, or hand-drawn sketch of the diagram and it writes the TikZ code that recreates it.
Do I need any special packages to compile the output?
Just \usepackage{tikz} in your preamble. When a diagram needs an extra TikZ library, the generated code includes the \usetikzlibrary line for it.
Can it draw circuit diagrams and graphs?
Yes. Circuits, graphs, trees, automata, and block diagrams all work; name the components and connections in your description and the generator picks appropriate TikZ constructs.
