wtf is kawarimi?

Kawarimi connects a browser based AI chatbot, such as ChatGPT, Claude, or Gemini, to VS Code so that code the chatbot writes can be applied directly to the file you are editing. It works through a Find and Replace pattern: the chatbot shows an original code block and a new code block, and clicking buttons in the Chrome extension sends that change straight into the active file in VS Code, without needing an API key and without copying and pasting by hand. The project ships as two paired pieces, a Chrome extension and a matching VS Code extension, both of which need to be installed and running for the workflow to work. After installing them, you open the file you want to change in VS Code and leave it active, wait for the chatbot to finish generating its answer, then click Find on the original block and Replace on the new block. Kawarimi then updates the file and saves it automatically. There are also controls for replacing every matching block at once, replacing only the first match, marking a replacement as done, and undoing a change with the normal Ctrl+Z or Cmd+Z shortcut. For the connection to work, both the Chrome and VS Code sides need to be running and talking over the same local port, which defaults to 10240. Support for using this on arbitrary custom websites is described as experimental and may not work everywhere. The README also includes a suggested prompt users can give the chatbot so its responses come back in a format Kawarimi can parse cleanly, asking for exact file paths and complete, unabbreviated code blocks rather than partial snippets or placeholders. This is a small developer tool aimed at people who already chat with AI models in the browser and want those answers to land directly in their code editor. The project is released under the MIT license.
