The trade-offs

Strengths and Limitations

Amp

Strengths

  • Agent-first workflow that spans the terminal, multiple editors, the web and Slack
  • Routes between frontier and fast models instead of locking to one
  • Thread sharing makes agent work collaborative across a team

Limitations

  • Usage-based pricing can be harder to predict than a flat seat price
  • Built around an autonomous agent rather than inline autocomplete

JetBrains AI Assistant

Strengths

  • Deeply integrated into JetBrains IDEs and their refactoring and inspection tools
  • One subscription covers AI Assistant and the Junie agent, and external agents can be driven from the same chat
  • Local models via Ollama or LM Studio work for chat, generation, commit messages and documentation
  • The credit quota is denominated in dollars, so usage is legible before it runs out

Limitations

  • Only useful inside JetBrains IDEs, and AI Free is unavailable in Android Studio and the Community editions
  • Cloud features are metered by a monthly AI credit allowance, with top-ups sold separately
  • The plugin is not bundled and is disabled by default, so it has to be installed and enabled
