Developers are using AI to write code, debug, and accelerate workflows. This list covers AI assistants that integrate with your editor, suggest code, explain errors, and help you ship faster. From pair programmers to documentation generators, these tools reduce boilerplate and cognitive load.

We've included tools that work with popular languages and frameworks. Some run locally; others use the cloud. Free tiers exist for most—enough to evaluate before committing. Pick based on your stack and workflow.
