Aider

Aider is a free, open-source command-line tool that turns your terminal into an AI coding session. You point it at one or more files, describe what you want in plain English, and it edits those files and immediately commits the changes to Git with a descriptive message — so every AI change is a clean, reversible commit and nothing is silently overwritten. It supports 100+ programming languages, works with Claude, GPT, Gemini, DeepSeek, and locally-run models, and can map an entire codebase so the AI understands how files relate. Released in 2023 by Paul Gauthier, it has 40,000+ GitHub stars and a large, active community. For biology students: use it to write Python scripts that parse sequencing output, automate repetitive cleaning of CSV exports from lab instruments, or build a small analysis pipeline — with Git tracking every change so you can always roll back.
