FILLING by Call Butler is a Chrome extension designed to simplify the process of filling out online forms. Utilizing generative AI, it allows users to enter their information in a free-form text format, which is then used to automatically populate various fields with a simple keyboard shortcut (Ctrl + Shift + F). This tool is particularly beneficial for frequent online users, salespeople, event attendees, and job seekers, enabling them to save time and effort by reducing repetitive data entry.

The extension offers secure local storage of user data, ensuring that no external access is involved. Users can utilize their own OpenAI API key for enhanced flexibility and control. While the free version limits input to 300 characters, a Pro version is available for $20 per year, increasing the limit to 20,000 characters and providing additional features. This tool is a valuable resource for anyone looking to streamline their online interactions.
