You'll finish with: You stop confusing the two.
Two different features share the word "project" and it causes more confusion than anything else in Claude.
Same word, two features
Only chat projects can be shared. If the goal is everyone working from the same context, that's the one — Cowork stays personal by design.
Chat project = shared filing cabinet everyone can read. Cowork project = your own desk, with your own files on it.
Ask it to save a file. Cowork saves one. Chat shows you the text and asks you to copy it.
If it says it saved something but you can't find it, you're in Cowork and looking in the wrong folder — ask it for the full path. If you expected Cowork and got text to copy, you're in a chat project with the same name. That's the whole confusion this chapter is about, and it catches everyone once.
