I haven't found it particularly effective for code synthesis, however, I do use it extensively for fiction generation. While I don't use its output verbatim, it serves as a great source of inspiration and guidance. Additionally, I've found it to be an excellent resource for personal, relationship, financial, and self-improvement advice. Of course, it's important to use your own judgement and not take everything literally, but it has often led me to valuable reflections and insights.
