An online tool that converts natural language descriptions of scenarios into calculated and validated probability tree diagrams, with AI refinement and export

What it is

Screenshot of the ProbPath homepage
probpath.com, as visitors see it

ProbPath is an online probability tree diagram maker that generates, calculates, and validates probability trees from natural language descriptions. Users describe a scenario in their own words and receive a complete probability tree with all branch probabilities computed and validated within seconds.

The tool supports refinement through conversational chat or direct canvas editing. Users can follow up with natural language instructions or click nodes and branches to adjust labels and probabilities, with all downstream calculations updating instantly. It validates that sibling probabilities sum to exactly 1 and handles both independent and dependent events, including draws without replacement.

ProbPath exports probability trees as PNG, PDF, or SVG files suitable for homework, slides, and reports. The tool runs entirely in a browser with no installation required and understands natural language descriptions in multiple languages.

  • Natural language scenario description
  • Automatic calculation and validation of probabilities
  • Conversational refinement via chat
  • Direct canvas editing of nodes and branches

Questions from the bench

Is ProbPath free to use?
Yes, ProbPath offers a free Basic tier with 5 free AI credits, manual editing, up to 3 saved probability trees, and white-background PNG export. Paid credit packs unlock additional features like PDF and SVG export, transparent PNG export, and unlimited saved trees for 30 days.
Can I edit trees after they are generated?
Yes, trees can be edited in two ways: by following up with natural language instructions or by clicking any node or branch on the canvas to adjust labels and probabilities directly. All downstream calculations recalculate instantly.
Does ProbPath validate probability calculations?
Yes. ProbPath validates every branch group so sibling probabilities sum to exactly 1, and all path probabilities are computed automatically without requiring manual multiplication.
Can ProbPath handle conditional probability and dependent events?
Yes. ProbPath can describe dependent events like drawing marbles from a bag without replacement and updates the conditional probabilities at every stage of the tree automatically.
What export formats are available?
With the free Basic tier, users can export white-background PNG. With a paid credit pack, PNG, PDF, and SVG formats are available and suitable for homework, lecture slides, and reports.
