Appreciate the post and thank you!
I think for me and the idea I saw a fundamental shift in the experience chatGPT provided once it was able to remember cross/post chat things. The APIs do not have this offering and are pretty bare, so being able to put this on top of any LLM API I think is a value add.
I am curious how you are using Claude in your case? Web-ui? Co-Work? Does not seem like API, but would help me.
