Run real experiments. Not just surveys.
Probova is built for experiment design and A/B testing. Randomly assign participants to conditions, make each condition a full interactive experience, a chatbot, a prototype, a custom task, not just different wording, and export analysis-ready data traceable to every participant.
Built for experiments, not just questionnaires.
In an experiment the condition is the treatment. Probova lets your conditions be anything you can build, holds everything else constant, and returns data clean enough to publish or ship on.
Random assignment, controlled conditions
Randomly assign participants to arms and hold everything constant except what you are testing. Between-subjects designs, A/B and multi-arm tests, with who-saw-what recorded for every participant.
Conditions you actually build
Each arm can be a full interactive experience rendered live from your own HTML, CSS, and JavaScript. A chatbot, a prototype, a game, a standalone site with no survey chrome. Your manipulation stops being a wall of text.
Analysis-ready data, per subject
Carry condition labels and IDs into the experience and pull behavior and timing back out. Everything exports to Excel, CSV, Stata, or SPSS, ready for R, traceable to the participant, the condition, the version, and their randomized order.
The pieces a real study needs.
Experiment design, random assignment, conditional logic, interactive content, and analysis-ready exports. What researchers and product teams reach for on day one, not as paid add-ons.
Experiment design
Build between-subjects studies, A/B and multi-arm tests from a visual flow. Branches, randomizers, and conditions compose into the design you need.
Random assignment
Randomly assign participants to conditions, and shuffle questions, choices, or matrix rows. Each participant's actual order is saved for the export.
Code blocks that render
Write HTML, CSS, and JavaScript and it runs live for participants. Build interactive tasks, chatbots, prototypes, or a standalone experience with no survey chrome.
Logic + branching
Drag-and-drop logic editor with conditional branches and per-question display rules. Edge cases stop being a pain.
Analysis-ready exports
Excel, CSV, Stata, or SPSS, ready for R, with per-page timings, condition labels, custom variables, and each participant's actual randomized order. Bring your own analysis.
