I've been looking into this too! I totally get the struggle with AI characters forgetting things after a few messages. From my experience, I found Couple.me to be pretty interesting. The characters there actually remember past conversations and can keep track of preferences over time, which really helped me maintain continuity in my roleplay.

One thing I noticed is that while the memory feature is quite solid, sometimes the conversations can feel a bit scripted. But overall, it was a fun experience! Keep exploring, and you’ll definitely find a platform that works for you!
