Claude Code vs Work vs Web (caveman version)

The Three-Tool Rule

Tool mismatch is the biggest AI time-sink. Web is for talking. Work is for living. Code is for shipping.

Useful output = Task Fit × Tool Power. Wrong tool, zero fit, no model rescues you.

The three tools

ToolWhereBest for
Claude Webclaude.aiOne-off questions, brainstorming, document analysis, artifact prototyping
Claude WorkDesktop + mobileInbox, calendar, meeting prep, voice dictation. OAuth to Gmail, Notion, Slack, Linear, GitHub
Claude CodeTerminal CLIMulti-file refactors, debugging, builds, tests, PRs

Decision tree

  1. Files in a project? → Code.
  2. Inbox, calendar, connected app? → Work.
  3. One-off thought, paper, sketch? → Web.

Heuristic

Copy-paste code or a file twice in Web → switch to Code. Asking Code “is this email polite enough” → switch to Web or Work.

Worked example

45-min Web chat with two file copy-pastes. Context drifts. Bug ships. Same task in Code: 8 min. 37 min saved per misroute. Five a week → 150 hours a year.

Recap

  • Files → Code. Inbox → Work. Thought → Web.
  • Useful output = Task Fit × Tool Power.
  • Two copy-pastes in Web = wrong tool.
  • The win is routing, not a smarter model.
