4 anthropic tools, completely different jobs:
claude.ai ... chat, drafts, quick research
cowork ... work agent, browser use, file access, day to day ops
claude code ... build, automate, terminal, root control
most people pick the wrong one, then blame the tool
start with claude.ai if you're new
move to claude cowork when you want moer power
move to claude code when you're ready for the real game
