sam-siavoshian/morse is a tool that writes and applies code with AI based on the screen of a running desktop app or website once you request the change you want. According to the repository description, it can apply changes even to apps whose source code is not public. The latest public release is v0.3.4, and the provided material contains no changelog for that version.
The tool is used to customize apps that appear on screen with the Claude Code, Codex, or API key the user already uses. The README explains that no separate server or account is required. The applied result can be saved as a mode and applied again, read and edited, or turned off. It supports web-technology-based apps and browser sites, is written in JavaScript, and uses the MIT license. Targeting closed-source apps is significant in that it attempts screen-based changes even when the source cannot be modified directly.
That said, the supported scope is limited to web-technology-based apps and browser sites, and it does not bypass an app's private servers or paid access. It is therefore closer to a way of applying, as a mode, the changes that fall within what the screen offers, rather than a tool that arbitrarily rewrites an entire app. Nothing in the material says what changed in v0.3.4, so it cannot be judged. One has to take into account that the evidence for confirming the scope of application and the improvements in each version is limited.
