Which ChatGPT plans can add Fincanva?
ChatGPT lets you add a custom app like Fincanva on the Pro, Business, Enterprise and Edu plans, on the website only, not in the mobile apps. On Pro, ChatGPT allows a custom app to read and fetch only, so asking it to save a strategy or a screener needs Business, Enterprise or Edu, where full support is in beta. These are ChatGPT's rules, set by OpenAI, and they change often; OpenAI's help article on developer mode and MCP apps states the current ones.
