Tips for Better Results
Be specific. "Fix my code" gives a generic response. "This Python function throws a KeyError when the dict is empty — fix it and explain why" gives a useful one.
Give context. For code tools, mention the language and what the code is supposed to do.
Iterate. If the first output isn't right, try rephrasing your input or adding more details.
Privacy
Your inputs are sent to OpenAI's API for processing. Don't paste sensitive information (passwords, API keys, personal data) into any AI tool. Inputs are not stored or used for training.
