Have you seen https://pygpt.net/ ? Overloaded interface and little unfortunate name aside, this seems to be the best one I tried.
What's wrong with the name? Are you referring to the GPT trademark? That was rejected.
What I meant is the "Py" prefix is typically used for Python APIs/libraries, or Python bindings to libraries in other languages. Sometimes as a prefix for dev tool names like PyInstaller or PyEnv. It's just less often used for standalone apps, only to indicate the project was developed in Python.
