NovelAI Assistant is a free Chrome add-on developed by tacyan. It is designed to enhance the user experience on the NovelAI platform by providing additional features and functionalities.

One of the key features of NovelAI Assistant is the ability to move the images in NovelAI's History using the up and down arrow keys. This feature allows users to navigate through their image history more easily and efficiently. Additionally, NovelAI Assistant also enables users to temporarily save the Prompt and Negative Prompt for Novel spells in Chrome's local storage. This means that even if the user accidentally closes the icon while typing, the browser will remember their input, making it more convenient for them.

Furthermore, NovelAI Assistant displays a list of memos below the memristo, providing a simple and organized way for users to create and save memos. Users can easily add titles to their memos, making it easier to find and reference them later. Once a memo is saved, the prompt and negative prompt values are cleared, allowing users to start afresh with their next input.

Overall, NovelAI Assistant is a user-friendly and practical tool for NovelAI users. If you find it helpful, don't forget to give it a star and show your support to the developer.
