Decision Tree Flowchart Maker
Turn complex choices into clear, visual decision paths — instantly.
Describe your decision scenario and let AI build a structured flowchart with branches, probabilities, and outcomes. Customize every node and share in seconds.
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.

How to Make a Decision Tree Flowchart
From blank canvas to finished diagram in three steps.
Describe Your Decision
Type your question or scenario into the prompt. The AI builds a branching flowchart with decision, chance, and outcome nodes.
'Should we expand to the EU market?' — AI generates root node, investment branches, demand outcomes, and probability labels.
Customize the Tree
Add or remove child nodes, rename labels, set probabilities, adjust colors, and choose your layout direction using the config panel.
Change 'High Demand (0.7)' to '0.65', recolor chance nodes to orange, switch layout to top-to-bottom.
Export and Share
Download your decision tree as a PNG or SVG, copy a shareable link, or embed it directly on your website or internal wiki.

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.
