I tested IKI.AI alongside Afforai ( which I also love). Initially, I didn’t see results right away, but after some time, IKI.AI worked just as well as Afforai. Both tools are great in their own way. The main difference is that Afforai reads books on demand, while IKI.AI seems to already have the info loaded after a bit. IKI.AI provides instant results, while Afforai may take a few seconds to a minute, but it's not a big deal. As a first impression, I really love IKI.AI. It also answered some critical questions that Afforai couldn’t, and I appreciate that it feels less restrictive. Overall, I really like it and give it 5 stars.
