Among the reviews analyzed, Thea: Study Smart appears to be a valuable free study tool that uses AI to generate summaries, flashcards, and practice quizzes from uploaded materials. A recurring theme was appreciation for its extensive free features, which help with exam preparation and active recall. However, some sampled reviews reported that recent updates introduced a paid subscription, locking previously free features, which frustrated many students. Another recurring complaint involved technical issues, including the app failing to open on certain devices and uploads getting stuck at a percentage. While many users praised its effectiveness for revision, some noted that question quality could be too simple or repetitive. Best suited for students who want a cost-effective, AI-driven study companion, though it may disappoint those expecting a fully native app or seeking more advanced features like an AI tutor or audio support.

Uploading files is slow or gets stuck Many users report that uploading PDFs, images, or other files frequently stalls at a certain percentage (e.g., 28% or 55%) or takes an excessively long time, hindering study workflow.
Question quality and accuracy issues Some users complain that generated questions are too simple, repetitive, or irrelevant, and sometimes the AI misinterprets content, leading to inaccuracies in study materials.
