Questions

Do I need to know decision analysis?
No. You describe the decision or start from a template, and DecisionBranch tells you the best option, what it's worth and what would change it, in plain words. The technical terms sit beside each result if you want them.
Is my data private?
Yes. Your trees are private unless you choose to publish them, and we never sell your data or show ads. If you use the AI builder, your description is sent to our AI provider to draft the tree and isn't used to train models.
Can I export to PowerPoint?
Yes. Pro exports a 16:9 PowerPoint slide with the tree and the Best option callout, plus a slide-ready PNG and a PDF report.
How is this different from Lucidchart or Excel add-ins?
Drawing tools like Lucidchart draw the tree but calculate nothing, and Excel add-ins calculate inside spreadsheet dialogs. DecisionBranch does both: it builds the tree, works out the best option, shows when the answer would flip and exports it for your deck.
Is it free?
Yes. Building trees, the best option and expected value, sharing by link and three AI builds a day are free, with no signup. Pro adds unlimited private trees, PowerPoint and PNG export, the deeper analysis and unlimited AI builds.
Can AI build the tree for me?
Yes. Describe the decision in a sentence and you get an analyzed tree with every assumption marked, so you can check the numbers before you rely on them. Three AI builds a day are free.
