Empower your school with personalized test prep

After the 72-hour free trial (which requires a credit card to prevent spam and duplicate sign-ups), students can use Incublia for free with limited features. The free tier includes access to up to 100 practice questions without hints or explanations. For a more personalized and beneficial experience, we recommend upgrading to a paid Incublia subscription to get personalized study plans, full-length practice tests, projected scores, our AI tutor, and more.

Incublia offers 9,000 SAT practice test questions plus 30 full-length adaptive SAT practice tests. Incublia was built for the digital SAT, and its handcrafted content is based on the College Board's Bluebook digital SAT. Incublia also offers extensive support for the ACT with 5,000 questions and 20 full-length enhanced practice tests. Incublia is one of the few platforms to offer fully aligned material for the new, Enhanced ACT. Incublia also offers 4,000 PSAT questions, 10 full-length PSAT practice tests, and question banks for AP Biology, AP English Literature, AP World History, AP US History, AP Pre Calculus, AP Calculus AB, and AP Calculus BC.

We built a system that interfaces with foundational LLMs to facilitate conversations between the user and the Incublia bot. We can plug in various generative AI models to this system and rapidly experiment in order to evaluate which foundation model can deliver the most helpful, conversational, and natural-sounding study buddy for users. Hints are generated by AI, and answer explanations are augmented by AI. Anything that is AI-generated is also human-verified by Incublia's Curriculum Team.

For a given question, we "show" the model additional information about the question. This results in higher-quality, more specific, more relevant responses and reduces the risk of the model veering off in its response. This data will also be collected and used to improve the efficacy of responses and improve our ability to generate content. Additionally, unlike ChatGPT, all questions and answers are human-verified by Incublia's Curriculum team to ensure accuracy.
