FAQ
Frequently Asked Questions
What is a decision tree creator?
A decision tree creator is an online tool that lets you build visual diagrams mapping decisions, chance events, and outcomes as a branching tree structure. MakeCharts provides an interactive editor with Decision, Chance, and Outcome node types, edge condition labels, and probability inputs — plus an AI generator that builds an initial tree from a plain-language description.
Is this decision tree creator free?
Yes. You can create, customize, and download decision trees for free without signing up. Free accounts also include a limited number of AI credits to generate trees from natural language. Paid plans unlock more AI credits, SVG exports, and embed codes.
How do I make a decision tree online with AI?
Type your decision scenario into the input box and click 'Create Your Decision Tree.' The AI reads your description, identifies key decision points, chance events, and outcomes, and builds an initial tree you can then edit. You can add or remove nodes, change types, and update edge conditions directly in the editor.
What types of nodes does the decision tree tool support?
MakeCharts supports three node types: Decision nodes (for choices you control), Chance nodes (for probabilistic events), and Outcome nodes (for end results). Each type has a distinct color you can customize, making it easy for readers to follow the logic at a glance.
Can I add probabilities to my decision tree?
Yes. Each edge (the line connecting two nodes) supports a probability value between 0 and 1, plus a text label for the condition or event name. You can toggle probability display on or off in the Display settings panel.
What is the difference between a decision tree generator and a mind map tool?
A decision tree generator is designed specifically for decision analysis — it supports typed nodes (Decision, Chance, Outcome), directional flow, and probability-weighted edges. Mind map tools are better for free-form brainstorming without directional logic. MakeCharts offers both chart types so you can choose the right one for your task.
Can I change the layout direction of my decision tree?
Yes. You can switch between a left-to-right horizontal layout and a top-to-bottom vertical layout in the Layout settings panel. You can also adjust node width, node height, horizontal spacing, and vertical spacing to fit your content.
How do I export or share my decision tree?
Click the download button to export your tree as a PNG or SVG image. You can also generate a shareable link that anyone can open in a browser, or copy an embed code to display your tree on a website (Plus/Pro plans).
Does the decision tree creator work on mobile?
Yes. MakeCharts is fully responsive and works on phones and tablets. For complex trees with many nodes, a larger screen gives you a better editing experience, but you can view and share trees on any device.
Can I use this tool to build a decision tree for a business presentation?
Absolutely. The decision tree creator is designed for presentation-ready output. Export a high-resolution PNG or SVG, drop it into PowerPoint, Google Slides, Keynote, or any document tool, and your decision logic will be clear and polished for any audience.
