What do parents and students say about Astra AI?
Real words from students and parents who learn with Astra AI.
“Dude, I was really sick and missed a whole week right when they started a new unit. I opened Astra AI just for fun, typed ‘explain this thing,’ and it walked me through everything from zero to done. Like… what?! I went back and didn’t feel behind at all. Guess who won’t need tutoring for a while? 😴😴” Liam (Student) ⭐⭐⭐⭐⭐
"Better than any tutor. Unreal how good it is." ⭐⭐⭐⭐⭐
"Much cheaper than a tutor and explains things even better!" ⭐⭐⭐⭐⭐
"It helps me a lot. I understand my homework better and can prepare for tests easily!" ⭐⭐⭐⭐⭐
"Great tool! Studying is much easier and more fun." ⭐⭐⭐⭐
"My daughter used Astra AI, and I can hardly believe how much easier it made studying for her. Before, she would just stare at problems without knowing where to start. Now, she solves them easily and even enjoys math. The other day, she proudly came to me and started explaining a topic as if she were the teacher! I’m so happy to see her so motivated. Thank you!!!" ⭐⭐⭐⭐⭐
"This app is truly amazing. We were so worried about this year’s chemistry course, but it turned out to be super simple. The best part is that it doesn’t just give answers but walks you through the steps, so you actually understand how it works. We are extremely satisfied!" ⭐⭐⭐⭐⭐
"Astra AI is awesome. Now I have the same grades as before, but I no longer need tutoring – it’s much cheaper and saves me a lot of time traveling to lessons. If I do an exercise, I can instantly check if I got it right." ⭐⭐⭐⭐⭐
"To put it simply: My kids are equally excited about Astra AI and the Matura AI tutor. And as a mom, I just have to say: THANK YOU!" ⭐⭐⭐⭐⭐
"It explains well and includes additional questions that guide you to the correct answer, which is great. An excellent tool for independent learning." ⭐⭐⭐⭐
"A huge help. 😍 Excellent, because teachers often don’t explain things well. This AI explains better than any teacher. 10/10." ⭐⭐⭐⭐⭐
"The app is great because it also makes me think on my own while providing clear explanations. It especially helped me with math because I finally understood how to explain and solve problems." ⭐⭐⭐⭐⭐
Stoichiometry and acids, finally clear.
“I personally found myself struggling with stoichiometry questions and acid-base problems, but that all seemed to change once I started using Astra AI.”

What does research tell us about AI and student learning?
Research into AI tutoring shows promise, but the way it’s used matters. The important question is what students can understand, remember, and do independently afterwards.
01
The learning happens when they take part.
02
Getting it right isn’t the same as learning it.
03
How AI helps makes a difference.
About this research
These findings come from studies of different tutoring systems and learning activities. They are not results from a study of Astra AI.
Students learned more than twice as much.
In a Harvard study, students using a purpose-built AI tutor achieved more than double the learning gains of students in an active-learning classroom - in less time.
