the OpenAI Assistant API is really useful, but a lot of people can't or don't want to build their own UI on top of it. I made Appified so you can connect your OpenAI account and instantly get an embed URL for your assistant that you can deploy on any website via iframe.

It uses vercel, including the ai sdk, for streaming chats. I also built a python backend for handling tool calls. It can handle webhooks, API calls, and URL scraping for your assistant so you don't have to build those yourself. Add in code interpreter and file search from the native OpenAI functionality and you can make some really powerful assistants.

The best examples that my customers have come up with so far are using Zapier / Make.com to connect their assistant to other tools via webhooks. Anything from chatting with leads and collecting contact info, to generating Google Slides or Docs with information inputted in the chat.
