PromptGPT is a free Chrome add-on developed by Eeswar Kurli. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. PromptGPT aims to enhance the ChatGPT experience by allowing users to save their most used prompts.

One of the standout features of PromptGPT is the Prompt Bar, which enables users to quickly browse and select saved prompts by simply pressing "/". This feature streamlines the process of accessing frequently used prompts, making it more convenient for users.

Another notable feature is the Rich Template Engine, which provides shortcuts to fill saved prompts. Users can pass in custom values when using a shortcut or rely on default values. This flexibility allows for more personalized and tailored interactions with ChatGPT.

PromptGPT also offers a Custom Workflow feature, allowing users to build their own prompt dictionaries that align with their specific workflow. The extension provides examples to help users get started in creating their custom workflows.

Keyboard Navigation is another useful feature, enabling users to navigate the prompt bar using arrow keys. Additionally, users can quickly save their last prompt by pressing "^ + shift + s".

Accessing the prompt library is made easy through the extension icon in the browser's extension bar. By right-clicking the icon and selecting "options", users can easily manage their prompt library.

It's important to note that PromptGPT is currently in active development, and the developer welcomes feedback to further improve the extension.

Overall, PromptGPT is a valuable tool for ChatGPT users, offering convenient prompt management and customization options to enhance their experience.
