Question: Is there a code editor that uses AI to assist with writing code and has a searchable command palette?

If you want an AI-augmented code editor with a searchable command palette, Codeium is a great choice. It supports more than 70 programming languages and works with major IDEs. Codeium also has features like advanced code completion, AI-powered search and an AI chat assistant that generates boilerplate code and suggests bug fixes. It's geared for both solo developers and teams, with a variety of pricing plans depending on your needs.

Another big tool is GitHub Copilot. This AI-powered developer assistant offers context-aware help in many parts of the development process, including code completion and natural language prompts. It also offers chat help and works with many IDEs and services. GitHub Copilot can help you work more efficiently and screen for security vulnerabilities, so it's a good all-purpose developer tool.

If you want a high-performance editor, Zed could be for you. Zed is an IDE with the power of a heavy-duty editor but the response time of a lightweight one. It's got AI-powered code generation with GitHub Copilot and GPT-4 integration. It supports multiple languages and has advanced collaboration abilities, making it good for solo developers and teams.

Last, you could look at Sourcegraph, which offers a variety of tools including an AI-augmented coding assistant called Cody and more advanced code search abilities. It can help you navigate code across many repositories and make large-scale changes to code, which is useful for developers working on big codebases. It also works with common IDEs and can be run in the cloud or self-hosted.
