The real difference

Chat:

The skill you need: clear prompts

Output quality: generic unless you prompt very well

The vibe: texting a very smart stranger

Cowork:

The skill you need: clear context files (your style, your rules, your examples)

Output quality: sounds like you. Because it read your files.

The vibe: working with an assistant who read every brief

Projects:

The skill you need: picking the right files and clear instructions

Output quality: sounds like you. Because it has your guides.

The vibe: a team member who knows your playbook
