Qodo (formerly Codium) analyzes your code and generates meaningful tests to catch bugs before you ship. Qodo maps your code’s behaviors, surfaces edge cases, and tags anything that looks suspicious. Then, it generates clear and meaningful unit tests that match how your code behaves. Get full visibility of how your code behaves, and how the changes you make affect the rest of your code. Code coverage is broken. Meaningful tests actually check functionality, giving you the confidence needed to commit. Spend fewer hours writing questionable test cases, and more time developing useful features for your users. By analyzing your code, docstring, and comments, Qodo suggests tests as you type. All you have to do is add them to your suite. Qodo is focused on code integrity: generating tests that help you understand how your code behaves; finding edge cases and suspicious behaviors; and making your code more robust.

Ask questions or generate code with the context of your codebase for accurate results. This also works with choosing specific folders, online docs, terminal content, files, and more. PearAI can directly code in your files, and allow you to see diffs. Try CMD+I (CTRL+I on Windows). Here, we ask PearAI to help us add error handling and comments. Without writing a single line of code, we were able to make a new feature in an unfamiliar codebase: adding a documentation page to the PearAI landing page. Speed up your development process by seamlessly integrating AI into your workflow. PearAI's goal is to reduce the time it takes for an individual to go from idea to creation. Coding itself is a crucial tool in product development, and we believe that with the advancement of AI, it may drastically change over the coming years. We aim to build the environment that will encompass these changes, both in the short-term and long-term.

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.
