Gemini Web Utility is a free Chrome extension designed to enhance the functionality of the Gemini web app by providing various quality-of-life improvements. Key features include Clean Copy, which removes unnecessary prefixes from text selections, and Copy as Markdown, allowing users to copy responses in a Markdown format. Additionally, the tool offers Code Block Copy Fix to eliminate line-number clutter from copied code blocks, ensuring a cleaner output for developers and writers alike.

The extension also introduces a settings panel for easy feature toggling and shortcut customization, along with an Auto-Expand Responses option that addresses truncated replies. Users can export conversations to local Markdown files and remove watermarks from Gemini-generated images, making it a versatile tool for improving productivity within the Gemini environment without disrupting the existing workflow.
