Aide

CodeStory

Aide proactively proposes fixes or asks to include files that may be missing in the context. Our agent can do so by iterating on linter errors and pulling in relevant context using LSP tools. Go ahead, and do AI-edits on top of your coding session. We keep slim, VS Code-native checkpoints (we don’t use git) to easily roll back to previous states, in case the agent made any mistake. We try to make Aide feel like a real engineer to pair-program with. Chat about a problem by @’ting the file(s) and then jump into edits, or go from a smaller set of edits and discuss their side effects. Taking inspiration from MacOS spotlight, we created a floating widget you can invoke with CMD + K. If you have a text selection active, you quickly prompt a change for it. We ship a binary called Sidecar which takes care of preparing and sending prompts to LLMs, as well as giving them access to editor features.
