what is popchat fr?

PopChat is a small macOS menu bar app that gives you a quick chat panel for AI models. You press a keyboard shortcut, a floating window appears, you type a message, and the panel goes away when you are done. It is designed for short, temporary conversations rather than long sessions, and it works with lighter models that run locally on your machine. The app supports any chat provider that uses an OpenAI-compatible interface. That includes OpenAI itself, OpenRouter, custom endpoints, and local model runners like Ollama or LM Studio. Local models need no API key at all. You can switch between providers and models from a small menu in the panel header. The app also supports slash commands, which are your own reusable prompt templates with a placeholder for your input. A larger draft editor is available for longer messages. One notable design choice is that the panel never steals focus from whatever app you are working in. It appears on top, you type, and when you dismiss it your cursor returns to where it was. You can pin the panel open if you want to keep messages visible as a reference. On macOS 26 the panel gets a translucent glass-style appearance with adjustable tint, while older macOS versions get a solid panel. The app respects system accessibility settings like Reduce Motion and Reduce Transparency. Installation is straightforward: download a disk image from the GitHub releases page, open it, and drag the app to your Applications folder. It requires macOS 14 or later. Developers can build from source using Swift Package Manager and a provided shell script, which signs the app locally. There is no Xcode project file, just the package manifest and build script. Settings let you configure providers, web search engines, custom commands, and the global hotkey. API keys and conversation history are stored as local files, not in the macOS Keychain. The developer notes this is intentional because the ad-hoc signing process changes the app identity on each rebuild, which would cause Keychain password prompts. The project is MIT-licensed, at version 0.1.1, and was built for personal use. It deliberately omits code execution, plugins, voice, and multi-window support.
