Our Verdict
Aider is the terminal-native answer to AI pair programming: point it at your repo, describe the change, and it edits across files with Git-aware diffs, committing with a sensible message as it goes. It works with virtually any model — Claude, GPT, Gemini, or a local one through Ollama — and, being free and open source, you pay only for API usage. That cost can creep up in long multi-file sessions, and there's no GUI. For developers who live in the command line, it's the most natural way to pair with an AI.
