MemoryGPT is a free Chrome extension developed by Wynter Jones. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools. The main purpose of this extension is to assist users in counting the tokens used in their ChatGPT conversations.

With MemoryGPT, users can easily keep track of the number of tokens used in their chat sessions. This is particularly helpful for users who want to stay within the 4096 token limit. The extension provides a clear and accurate count of tokens, allowing users to manage their conversations effectively.

Additionally, MemoryGPT offers a useful feature that allows users to toggle the display of "forgotten" tokens.
