Ratings and reviews

I have always been very skeptical of AI, especially using AI for therapy. however, like a lot of people therapy isn't always affordable or available/easy to obtain. I've tried several other AI therapy apps. Some lure you in an.d then drop a paywall in front of you that you have to pay for in order to keep using the app, and some are too repetive or simplistic in their responses. So far, Onsen doesn't do any of that, and it has helped me so much in only a few hours of use.

The insight into myself that this has given me, in just the few days that I've used it, is great. It speaks cleary and in an easy to understand way. If I ask a question, it really gives good information, connections, and ideas for moving forward. Plus, it helps you to see patterns in your behavior you probably havent noticed. It really is like a little therapist in your pocket. It's perfect for introspection and guidance. You will only get out what you put in, though, just like regular therapy.

I'm a therapist's nightmare, a pharmaceuticals dream come true, & a 'menace' to society. Therapists, medications, rehabs, hospital stays....I've done them all. Some work a little, the rest not at all. I've been diagnosed with multiple mental health issues; I know the struggle. Then this app comes along. I was skeptical at first, but decided to try it. I'm so glad I did. This app has done more for me in 3 days then my therapist has done in months. That should tell you something. Highly Recommend
