                                    Easily duplicate your robots to handle pages with a similar structure. For instance:

                                    If you've created a robot for producthunt.com/topics/api, you can duplicate it to scrape similar pages like producthunt.com/topics/database without starting from scratch.
                                    How it works:

                                    Select a robot you want to duplicate.
                                    Use the duplication feature to create a copy of the robot.
                                    Customize the robot if needed, ensuring it fits the new page structure.
                                    ⚠️ Ensure the new page has a similar structure to the original for seamless functionality.

                                    This feature saves you time and effort while keeping your workflow streamlined for similar pages.
