CodeShift — AI Code Converter for VS Code
Convert code between programming languages instantly using Claude AI — directly inside your editor.
What it does
Select any block of code, hit Ctrl+Shift+Alt+K, pick your target language, and CodeShift converts it. The result opens in a side panel so you can compare and copy what you need.
No backend, no data collection. Your code goes directly from your editor to the Anthropic API using your own API key.
