Summary
Riley Brown shows off Bluey, an AI assistant he built entirely with Claude Opus 5.5 and no prior coding knowledge. Bluey is a monorepo containing a macOS desktop app and a companion iOS app that connect to each other, created in just a couple of prompts.
In the demo, Bluey listens to voice commands and follows the user’s mouse cursor. It points at specific items on screen, such as a chat name in a list, and runs research on how Claude’s new Projects feature works, highlighting the relevant element as it goes. Bluey can also take control of the computer: it opens ChatGPT and types a prompt, launches Chrome, navigates to Twitter, and posts a tweet on request.
The short clip is a quick look at what a non-programmer can now produce with a frontier coding model, and at how voice-driven computer-use agents can feel on both desktop and mobile. Brown notes that he has made the project public, so viewers interested in cross-platform vibe coding with Opus 5.5 can explore it themselves.
