Pros & Cons
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
ChatGPT
- Largest user base and ecosystem of any AI assistant, with the most third-party integrations
- Genuinely broad capability across writing, coding, research, and file analysis
- Custom GPTs allow tailoring the assistant to specific repeated tasks
- Frequent model updates keep it competitive on raw capability
- Free tier has usage limits and access to a lower-tier model than paid plans
- Can produce confident-sounding but incorrect information, especially without browsing enabled
- Breadth can mean less depth than a tool purpose-built for one specific workflow
- Data usage and training policies require attention for sensitive or regulated work
