This website lets you define a custom shortcut (or command) like gpt. When entered in your browser's omnibox or the site search bar, it either navigates directly to a URL (acting as a bookmark) or, when additional text is provided (e.g. gpt what day is Christmas), it parses your input to dynamically generate a URL.
The command operates in two modes:
1. Bookmark Mode: Use the shortcut alone to go directly to a preset URL.
2. Query Mode: Append additional query text (e.g. gpt what day is Christmas) and the system will parse your input to fill in parts of a template URL.
The URL template uses a custom DSL with two main components:
Option Component: {{opt:model,short:m,default:gpt-4o}} defines an option. For example, when you type gpt --model o1, the placeholder is replaced with o1.
Argument Component: {{arg:*}} captures the remaining arguments. Here, the asterisk means "use all remaining words". Variants like {{arg:0}} or {{arg:0,2}} allow for more specific selections.
Options work like command-line flags, enabling you to provide key-value pairs that customize the URL generation.
Arguments consist of the remaining input that isn’t recognized as an option. They are inserted into the template URL based on their position.
Internally, commands are stored as objects in our system. When a command is invoked, the input is parsed to extract options and arguments, which are then used to dynamically build the final URL based on your defined template.
Example 1: Bookmark mode – simply type gpt in your omnibox to navigate directly to a predefined URL.
Example 2: Query mode – type gpt what day is Christmas to generate a URL. For instance, if the template is:
https://chatgpt.com/?model={{opt:model,short:m,default:gpt-4o}}&q={{arg:*}}The {{opt:model,short:m,default:gpt-4o}} placeholder will be replaced if you specify an option like --model o1, and {{arg:*}} will be replaced with the rest of your query (e.g. "what day is Christmas").
