Aider
AI pair programming in your terminal — edit code with GPT-4/Claude
⚡ TL;DR
🎯 The Problem It Solves
You're coding and want AI to help — but switching to a web chat, copy-pasting, and managing context is painful. Aider runs in your terminal, watches the files you have open, and lets you request changes directly. It edits code, creates commits, fixes bugs, and sends diffs — all from conversation.
🔧 How It Works
Aider reads your repo files, sends them as context to an LLM (GPT-4, Claude, etc.), and the LLM generates edits. Aider applies those edits to your files with a unified diff format, shows the changes, and can auto-commit with meaningful messages. Features: multi-file editing, git integration (auto-commit, diff), image support, and voice mode.

Aider is free (Apache 2.0). You pay for your API usage (OpenAI, Anthropic, etc.). Running with local models works but with reduced capability.
