I've found Claude to be very useful when writing on the EA Forum. However, certain prompting and other techniques can help a lot.
The main use case I'm personally interested in is writing and interacting with content on the EA Forum / LessWrong and similar, but I'm sure there are other use cases that would be relevant to this community.
Thanks for sharing this! I've been testing this with ChatGPT 4.5 and so far it makes using it more fun and seems to possibly improve it as a brainstorming and soundboarding partner.
