File editing with repository context
Work on selected source files while using a compact repository map when the model configuration enables it.
Aider
Freemium
Edit a local codebase through terminal conversations with your chosen language model.
What is Aider?
Aider is an open-source AI pair programming tool for the terminal. Start it in a project, add the files you want to edit, and describe a feature, bug fix, or other change. It applies model-generated edits to those files and shows the differences.
Git integration records changes so you can inspect or undo them. Repository context helps the model understand related code without adding every file to the conversation. Aider can connect to supported cloud APIs or local models; results depend on the model and configuration.
What can Aider do?
Git-based change review
Automatically commit edits and keep preexisting changes separate. Diff and undo commands support reviewing the work.
Lint and test feedback
Lint edited files automatically or use a custom linter. Configure a test command and automatic testing to feed failures back into the coding conversation.
Provider and local-model choice
Use compatible model services or a local backend such as Ollama rather than relying on one bundled cloud model.
Use Cases
“Change an existing project”
Implement a feature or bug fix in the relevant files, then inspect the generated edits and validation results.
“Start a small code project”
Name new files and ask for an initial implementation that you can refine through follow-up requests.
“Maintain code and project text”
Use the same conversation workflow for tests, documentation, and configuration changes.
Frequently Asked Questions
How do I get started?
Install Aider using aider-install, change into your project directory, and launch it with a supported model. Supply an API key for a cloud provider, or configure a compatible local-model backend. Add the files you want to edit before describing the task.
Is Aider free?
Aider's source code is available under Apache 2.0. Cloud-model usage follows the provider's separate pricing and terms, while local inference uses your own computing resources. The software license does not include model credits.
Does local operation keep code off cloud services?
Files and context used in the conversation are supplied to the selected model. A cloud provider processes that input; a compatible local model is a different option. Aider's optional usage analytics are separate and require opt-in.
Can I control automatic commits?
Automatic commits can be disabled. By default, Aider skips Git pre-commit hooks; enable commit verification if you want those hooks to run.
Can it work on multiple repositories?
Aider edits one repository at a time. You can supply read-only context from another repository without treating both as a single editable workspace.
