  • Genuine lifetime pricing instead of an ongoing subscription
  • No window-switching keeps AI assistance inside the actual workflow

Cons
  • Requires either an existing API key or purchasing credits - no fully free tier
  • Team plan ($250 for 50 devices) is aimed at organizations, not individuals

  • Broader model support (Google, Anthropic, xAI) is still on the roadmap, not live yet
