The main reason I use #Claude as my primary #LLM service is because of the projects. I've created projects for Fedify, Hollo, and LogTape on Claude and use them for authoring docs. However, I'm not 100% satisfied with Claude's models, so I wish other LLM services would offer similar features to Claude's projects.

@hongminhee I think ChatGPT has something similar. Called "My GPT". You can upload documents, provide instruction, etc. as a starting point. Probably subscription only.
