User research for the AI era

Research that took weeks now takes an afternoon.

Recruiting, scheduling, and synthesizing a study takes weeks, so most decisions ship untested. Sentia runs agent swarms that represent your real users through the decision in hours, so every release gets researched.

Send an agent swarm that represents your real users through the complete journey, from first visit to confirmation. See where they go, where they backtrack, and where they give up, with the reasons in their own words.

Sentia is trusted by UX researchers at

Grounded in the tools your team already runs.

Sentia connects to the research, analytics, and delivery stack you already have, so twins are built from live sources and findings land where decisions get made.

01 / Evidence engine

Every source becomes cited evidence.

Decks, transcripts, and survey exports become goals, frustrations, and behaviors, each traced to the sentence or row it came from. Open the citation behind any trait.

A model of your product that compounds.

Under the hood

Behavioral model. Build and continuously improve your own model of how your customers behave.

Model, simulate, and calibrate on one integrated stack. Built from your data, measured against what your customers actually do.

01Behavior Model

Turn your interviews, surveys, analytics, and support data into a model of how each segment decides: goals, frustrations, habits, price sensitivity, trust, patience. Every value cites its source.

behavioral sciencepopulation priorsyour customer dataone model per workspace · every value cites its source

02World Graph

Query your segments, your product surfaces, and the behaviors connecting them. Every edge carries a predicted outcome, its confidence, its evidence, and its record against real releases.

querysegments · product surfaces · behaviors

03Forecasts

Forecast pricing, flow, copy, and roadmap decisions per segment, with the reasons behind each and how often the model has been right on that surface. Ship the changes that move the number.

04Calibration

Measure every forecast against real behavior once you ship and fold the result back into the model. When your customers change, the model changes with them.
