“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.”

Cesca V.

“Raena has helped me in so many ways! If I am struggling to understand an assignment, or need a little help in studying for a quiz or test, Raena has got me covered. The podcasts it creates helps me study anywhere, allowing me to manage time efficiently. Pulling all A's right now and it's all thanks to Raena!”

Reece B.

“I have been diagnosed in the past year with Macular Dystrophy, an eye condition in which I have loss of vision in my central vision. This makes is significantly harder and takes a lot longer to read documents, and see detailed. So, I signed up to Raena AI in an attempt to help summarise my Uni readings and documents, to help me read faster, and keep up with the content and my peers. I have been using it for a while now, it it has honestly saved my life! I no longer feel 'left behind' because it takes me longer to read, and i can't skim and scan. Now, I feel like I can keep up with my work, and finish my degree with good marks again! Thank you so much for helping me, I don't know what I would have done without it!”

“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.

“Honestly, Raena AI has saved my life. I am studying fast track paramedicine and am also working full time and before I discovered Raena I was falling behind in my studies and couldn't keep up.

“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
“I use Raena AI for every single test. As a student nurse taking anatomy and microbiology classes, Raena AI is a part of my study routine in every course I take. I went from getting 50s in my tests to 90s with the implementation of this tool. I have also shared this website with many friends and colleagues wishing to help them out, which they too have had positive experiences, and you can see in the picture I promoted this website multiple times.”

“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.

“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.”

“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.”
