Your terminal now ships with a senior dev

What it does — Aider is a terminal-based AI pair programmer that edits files directly in your local git repository. You chat with it in natural language, and it modifies code across your project, then commits the results with human-readable messages. It also supports voice input, image context, and a file-watcher mode that lets you trigger changes by adding comments in your IDE.

The interesting bit — Before editing, Aider builds a “repo map” of your entire codebase, giving the LLM enough context to navigate large projects without getting lost. The project also claims an 88% “singularity” score, meaning the latest release was almost entirely written by Aider itself.

Key highlights

• Plugs into almost any LLM—Claude, GPT-4o, DeepSeek, local models, or even web-only chats via a copy/paste bridge
• Auto-commits every change; undo or diff with standard git tools instead of hunting through chat history
• Understands 100+ languages and can ingest screenshots, web pages, and voice commands as prompts
• IDE-agnostic file-watcher mode lets you request changes by writing code comments
• Runs linting and tests after edits, then attempts to fix failures automatically

Verdict — Terminal-native developers who want AI assistance without leaving their shell or losing git history should try this. If you prefer a GUI-centric experience, look elsewhere.
