Introducing co-do.xyz [Source] - a demo and an experiment (with no warranties) of everything that we’ve talked about above.
Co-do is an AI-powered file manager that runs entirely in the browser. You grant it access to a folder on your machine, configure your AI provider (Anthropic, OpenAI, or Google), and ask it to help with file operations: listing files, creating documents, searching content, comparing files. It also has access to a number of pre-compiled WASM binaries for operations that you might want to perform on text files (for now, I’m hoping to bundle
ffmpeglater).

Is it perfect? No. But I think it demonstrates that the browser’s 30-year-old security model, built for running hostile code from strangers the moment you click a link, might be better suited for agentic AI than we give it credit for. However, I do think there should be a lot more investment from browser vendors in improving the primitives for securely running generated content (be it an ad, an LLM, or any embed).
