“Raena AI has made my revisions way easier. I am able to learn by generating quizzes and it improves the knowledge I take in from so many boring PowerPoints. Overall, it's fun to use!”
Sharol T.
University of Belize
“Raena AI has been instrumental in my studies, it breaks down large powerpoints used in lectures into manageable chunks, often only including the necessary information that will be examined. I could not go about my university life without it”
Tadhg F.
University of Galway
“It really helped me in my Mid-Year exams! I was so lost and the quizzes and summaries made me pass all my exams in my first year! THANK YOU!”
Cesca V.
The University of Malta
“Raena AI is an answered prayer for me, a light that guides me throughout my journey and dream of finishing my degree. It has the BEST features, all that I need to make me feel more motivated and engaged in my daily classes. The learning and information Raena AI is providing through my uploaded documents are all accurate! My grades now are all amazing!”
Laiza V.
Cap College Foundation Inc.
“It has provided concise summaries that have helped me SO much with studying for tests and mid sems”
Niamh M.
UWA
“I started my first year of medical school after a five-year break from studying, and honestly, I had no idea where or how to even begin preparing for my exams. I felt totally overwhelmed and convinced myself I wasn't smart enough to keep up. But Raena AI changed that. It gave me structure, explained difficult concepts in a way I could actually understand, and reminded me that I can memorise and learn everything, I just needed the right support. Now I don't just study, I study with confidence.”
Amal J.
Lithuanian University of Health Sciences (LSMU)
“Raena helped me a lot with exam preparation for classes that required learning abstract concepts. Especially the quiz mode! I find it very helpful to test my knowledge and find gaps in learning”
Leila S.
University of British Columbia
“As a college student, lecturers usually give 60+ PowerPoint slides per lecture. I would spend days going through each single slide and trying to get the right information from it, sometimes even getting the useless information. With Raena AI, it gives me the summary in seconds, plus I can get podcasts or flashcards to help me study much better. Using this tool, I am not behind anymore on any of my content and I can get more done than ever. Raena AI saves time and lives.”
Monike S.
Technological University Dublin
“I've been using AI to help me study physiology and anatomy. The breakdowns of extremely long lectures into tolerable reading sections has been extremely helpful.”
Reece B.
Ontario College of Health & Technology
“I typically use Raena AI for everything school-related, it's insane how such a platform could help a number of people. I use it especially for studying for my finals, every semester, as the work load in campus can be a little too overwhelming. I like summarizing my school PDF's beforehand to avoid burn out and I especially love how quirky the brain rot videos are because they help me understand better when I'm unmotivated. This website is too good, i had to put my girl friend on.”
Mac M.
Machakos University
“The podcasts have honestly been life changing and the quizzes keep me ready”
Patrice O.

“I could study my in-class powerpoint presentations made by instructors more efficiently with the Summary function”

“It saves me so much time on making flashcards and questions for myself. So I can just spend my time actively learning content rather than creating resources. The notes also summarise and make it easier for me to understand.”
Simran
Anglia Ruskin University Cambridge
“I'm writing this as the dentistry faculty top student of the first semester, with 3.93 GPA, thanks to Raena AI. I've discovered Raena AI at the second midterms and it literally changed my academic life. I use the summary option religiously. It simplifies the most complex lectures into something still detailed but much more understandble. I genuinly thank you for your services, my academic game can not be matched now. With gratefulness, Asel.”
Melike K.
Üsküdar University Dentistry
“I have used all of Raena AI's features but my most used features are the tutor and the quizzes. They're both really useful for revision and exam prep. I especially like that the quiz feature highlights the subtopics that you need to improve on. This helped give my grades a boost”
Chilandu P.
The University of Zambia
“It helped summarize large notes to better understand by highlighting the main points. It helped answer questions that I couldn't handle and explained things that I couldn't understand. It has helped me a lot.”
Helena T.
University of South Pacific
“Raena has allowed me to understand and simplify complex topics within accounting and finance. From this, I can implement small changes to my answer and overtime, this allowed me to make more comprehensive answers and in thus, allow me to get better grades.”
Yusuf A.
University of Winchester
“Raena AI helped me with understanding my study materials way faster and easier. Using raena to study led me to spend less time studing and have better grades.”
Filip H.

“I almost use it every day. I don't think I can live without it anymore. Because of Raena, my grades went up a lot, and it improved my way of studying.”
Moses B.

“Raena AI has cut my study time in half.”
Daniel L.

“Raena has helped me better understand the memorization aspects of science”
Miguel D.
Dalhousie university
“I use Raena Ai to make Ai generated podcasts that break down each portion of the chapter I am reading for all my classes. Makes it a lot easier to digest chapters and highlight what information is most important. I find it really helpful to download the podcasts to my phone and listen to them on the way to class. I also love to copy and paste my end of chapter vocab/definitions and create flashcards in seconds. I now spend less time preparing to study and more time actually studying.”
Sarah H.
Kennesaw State University
“When I have a lot of materials to read and go through, Raena AI gives me comprehensive and the most easy-to-understand summaries. Raena AI helps me understand even the most complex files that I don't have the patience to read at all. The flashcards feature as well helped me a lot understanding and retaining complex topics.”
Jillian L.
College of Nursing
“It has helped me summarize and convey ideas in a much more effective way! I have learnt with so much ease!”
