Even 'dumber' question here since I haven't used the product, what I'm looking for is to highlight code and then get answers based on the code - does that need the chatgpt part to work? (Trying to avoid chatgpt limits and not sure if this would be quering the chatghpt part or not) - please advise, ready to jump on this if this is available on the unlimited plan that doesn't need the chatgpt part.
