Pros & Cons

JetBrains AI

  • Code completion and Next Edit Suggestions remain genuinely free regardless of tier
  • Free AI tier (early 2026) provides real entry-level access to chat and code generation features
  • Integrated directly across all JetBrains IDEs without needing a separate tool
  • Free tier excludes Community Editions, Android Studio, frontier models, and Junie agent access
  • Credit-based system means heavier chat/code-generation users exhaust quotas faster than expected
  • Frontier model access requires higher-tier plans or credit top-ups

Aider

  • Every AI-made change is a real, revertible git commit
  • Works across multiple files in a codebase, not just single-file edits
  • Open-source and not locked to a single AI model provider
  • Requires comfort with the command line rather than a graphical IDE experience
  • No built-in chat sidebar or visual diff review the way some IDE-integrated tools offer
  • Users need to bring their own API key for the underlying AI model
