ChatGPT API Key Extension

ChatGPT API Key Extension lets you talk to ChatGPT through your own API key, so you can manage your usage directly and stay in control of how you connect to the model.

Basic history saving and downloading are included, making it easy to revisit past conversations or keep a copy for later reference. A simple cost estimation feature gives you a quick sense of what your messages are costing, helping you keep an eye on spending.

Before you send a message, the extension can check for personal information, adding a layer of protection against accidentally sharing sensitive details. Together, these features make everyday chatting with ChatGPT more convenient and more mindful.
