Prompster is a free Chrome add-on developed by lucas.aschenbach that enhances your chat bot experience by providing almost 200 predefined prompts directly within ChatGPT, Bard, and other platforms. By simply typing '/' followed by the keyword for your desired prompt and hitting 'tab', Prompster inserts the prompt into the input field without the need to leave the chat interface.

In addition to the extensive library of predefined prompts, Prompster also supports custom prompts. Adding your own prompts as slash commands to your library is as easy as two clicks, ensuring instant access whenever you need them. For more advanced use cases, Prompster allows you to enclose parts of your prompt with brackets, which are interpreted as variables and dynamically filled when using the prompt.
