Features

Everything You Need in a Decision Tree Maker

Powerful enough for analysts, simple enough for anyone.

AI-Generated Trees

Describe your decision in plain language and get a fully structured flowchart with nodes, branches, and edge labels generated instantly.

Three Node Types

Use decision nodes (choices), chance nodes (probabilities), and outcome nodes (results) to build accurate, professional decision trees.

Probability Labels

Assign probability values (0–1) to each branch so your flowchart reflects real expected-value analysis.

Flexible Layout

Switch between left-to-right or top-to-bottom orientations and adjust node size, spacing, and font size to fit any document.

Custom Colors

Set distinct colors for decision, chance, and outcome nodes to make your tree instantly readable at a glance.

Instant Preview

Every change you make — label edits, added branches, color tweaks — renders live so you always see the final result.

FAQ

Frequently Asked Questions

What is a decision tree flowchart maker?

A decision tree flowchart maker is a tool that lets you visually map out a decision by branching possible choices, chance events, and outcomes. MakeCharts uses AI to generate the tree structure automatically from a plain-language description, so you can focus on the logic rather than the layout.

How do I make a decision tree flowchart for free?

Open MakeCharts, pick the Decision Tree chart type, and type your scenario into the prompt. The AI builds your flowchart — no sign-up or credit card required. Free accounts get full access to the editor and can download or share the result.

Can I add probabilities to my decision tree?

Yes. Every node in MakeCharts has a probability field (0–1) and an optional value field. You can also toggle 'Show Probabilities' in the Display settings to annotate each branch with its probability label for expected-value analysis.

What is the difference between a decision node, chance node, and outcome node?

A decision node (square) represents a choice you control. A chance node (circle) represents an uncertain event with a probability. An outcome node (leaf) represents the final result at the end of a branch. MakeCharts supports all three types and styles each one distinctly.

Can I use this as a flowchart maker for other diagrams?

Decision trees and flowcharts share similar logic but differ in structure. MakeCharts is optimized specifically for decision tree diagrams with node types and probability fields. For general process flowcharts, MakeCharts also offers a separate Flow chart type.

How do I export and share my decision tree?

You can download your tree as a PNG or SVG file for use in presentations and documents. You can also copy a shareable link or use an embed code to display the diagram on a website or internal wiki — all from the Share menu.

Is this decision tree generator suitable for business presentations?

Absolutely. You can customize node colors to match your brand, adjust font sizes for readability at large screen sizes, and export a high-resolution PNG or vector SVG. The clean, structured output is presentation-ready without extra formatting.

Does the AI understand complex, multi-level decision scenarios?

Yes. The AI is designed to break down multi-stage decisions into hierarchical branches with appropriate node types at each level. For very large trees, you can also build manually by adding child nodes layer by layer in the config panel.
