Ask HN: Can AI writing services compete with ChatGPT?

I know there are a lot of AI writing services like Copy.ai, Grammarly, etc. They were doing quite well before ChatGPT came along. But people can use ChatGPT for free to help them write or correct their grammar. Does this kind of software still have value? If so, what’s their value? Companies like Copy.ai basically are just wrappers on top of GPT models. Their value was the UI where the users can write and save their articles. But you can do all this with OpenAI for free now. How can the AI writing services, like Copy.ai, compete with OpenAI?
