When should I use Claude chat/Projects ('co-work') versus Claude Code for building tools like spreadsheets or apps?

No firm rule was given. One participant described her own approach: she just tells Claude when she doesn't understand a term, and it explains itself in plain language instead of 'developer talk.' She also uses a Chrome extension that reads what Claude said and executes the described actions automatically so she doesn't have to do it herself. Another participant noted that literally asking Claude 'when should I use each part of you for what' will get you an explanation, and encouraged treating any uncertainty about the tools as something to just ask Claude directly rather than figure out independently.
