Open-source AI pair programming inside your terminal and git repo
Chat with an AI assistant from your shell, have it propose and apply code edits to files in your working directory, and keep full control of the final diff.
Every accepted change becomes a real commit with an auto-written message, so you can inspect, amend, revert or branch AI edits with ordinary git commands.
Aider builds a structural map of your project so the model understands where relevant code lives and can work sensibly in large, multi-file codebases.
Connect hosted models from Anthropic, OpenAI, DeepSeek and others, or point Aider at a locally hosted model to keep code on your own hardware.
Red-team and evaluate AI agents before they reach production
Adversarial evaluation of agents to surface unsafe, non-compliant or unreliable behaviour before they run against real users and real money.
Measure and track how much fine-tuning private models with LangTrain improves accuracy for your specific domain.
Verify that agent responses are repeatable and reliable enough for regulated workflows such as clinical, lending or claims decisions.
Evaluate agents that work across text, voice, vision and other modalities rather than text alone.
