I’m looking for practical experience from anyone who's already traveled this road. I built a suite of 21 custom GPTs focused on authors, publishing, and book marketing—tools for opportunity research, reader pain points, competitive gaps, book positioning, and related publishing workflows. Each was designed as a focused tool, not a general chatbot. My original plan was simple: distribute individual GPTs by direct link, with customers using them inside their own ChatGPT accounts. Then the ground shifted. OpenAI has ended new GPT creation and publishing on personal accounts. Existing GPTs still work, and ChatGPT Business may preserve some link-sharing options, but that feels more like a bridge than the long-term destination. So I’m now exploring the next question: What is the best way to turn an existing custom GPT into a standalone App or web-based tool? Ideally, I’m looking for a path that: - preserves the GPT’s instructions and workflow rather than rebuilding the concept from scratch; - gives authors and publishers a simple interface without requiring them to understand prompts; - allows me to control access and eventually sell individual tools; - does not require maintaining an elaborate SaaS operation. I’m not wedded to any particular platform. I’m interested in what people have actually built and deployed—whether with the OpenAI API, ChatGPT Apps, WordPress, no-code/low-code platforms, or another approach entirely. If you’ve converted a custom GPT into something customers can use outside the GPT Store ecosystem, what path did you take, and would you choose it again?
