The Research Lab Behind the App
What separates Santa from the crowded field of test-prep apps is not the interface, but the research underneath it. Santa is built by Socra AI, an education-technology company backed by the SoftBank Vision Fund.
Socra AI employs more than 34 AI and NLP researchers, including alumni of Stanford, MIT, KAIST, and other leading institutions, who build language models designed specifically for test preparation rather than adapted from general-purpose systems. That work has produced more than 15 peer-reviewed papers at top-tier venues, including NeurIPS, ICML, and ACL — a level of published research output more common in academic labs than consumer learning apps.
How the Technology Reaches the Student
For test takers, the payoff of that research is felt in two places: prediction and feedback.
As an official ETS partner, Santa currently provides 21 official mock tests and roughly 3,500 practice questions, with more to be added. Crucially, the platform uses SpeechRater® and e-rater® engines, ensuring that the practice scores learners receive serve as highly reliable indicators of their actual test-day performance.
That calibration is sharpened by scale. More than 4 million learners have downloaded Santa worldwide, and they have answered over 300 million questions on the platform. Every one of those responses feeds back into the prediction engine, which continuously trains and refines its estimate of a learner’s ability and likely score.
In practice, that means a student spends less time on material they have already mastered and more on the specific gaps standing between them and their target score. The personal AI tutor diagnoses where a learner is losing points, recommends what to study next, and adjusts as the learner improves — the kind of individualized pacing that traditionally required a private instructor.
The content itself is current. Santa has completed a full update to the 2026 revised TOEFL, aligning its question banks, mock tests, and scoring with the latest exam format so that learners are not preparing against an outdated version of the test.
What Comes Next
Santa’s roadmap points toward deepening the partnership and the dataset that distinguishes it. The company plans to expand its catalog of official ETS content, while continuing to refine the prediction engine as its question-answer dataset grows.
The broader ambition, Santa suggests, is to make rigorous, individualized exam preparation accessible to anyone — collapsing the cost and time barriers that have long separated well-resourced test takers from everyone else.
