Rating: 2/5 stars — feels like a total bait-and-switch. ​ Paywall!! It claims to be free, but you get locked out after two sample questions unless you pay $15/month. ​ It's just a standard AI wrapper with a pretty UI. ​ Skip the subscription and just use ChatGPT, Khan Academy, or NotebookLM for free instead.

It's disheartening to hear you feel misled about the app's offerings. The subscription model is designed to allow users to explore all features for free daily before deciding to subscribe. Thank you for sharing your thoughts, and we hope you find the right resources that meet your needs!

i downloaded this app for my TKA prep in Indonesia, expecting it to match the advertisements i've seen. but what i got is just a complete AI mess, the questions type doesn't even match how the test's format should be, and the grading system is an utter garbage- giving me grade below 100 even with a correct answer and quick solving. and keep in mind, it's a multiple choices question, so missing things in context is not even possible considering the answers are tied to them.

It's a very good app. I think it will help me to achieve good results in my exams.I'll always ask help from the amazing and useful app. I wish that this app will never disappoint me. From 8 December, my Scholarship exam will start. So I'm thinking that I will be motivated from this app. From the year of 2026, I was searching such an app like Astra AI.I think that I've found it at an actual time. I will ensure the best use of the app. No other apps are as useful as this app.Thank you Astra AI.
