GPT Master
GPT Master is a free Chrome extension that turns ChatGPT's web interface into a structured workspace. It adds essential productivity features such as a prompt library with quick // access, folders and bookmarks for organizing conversations, a minimap for navigating long threads, and bulk actions to move or archive multiple chats at once. The extension is designed to work on top of chatgpt.com regardless of the user's plan, including Free, Plus, Team, Pro, or Enterprise, and is compatible with Custom GPTs, Projects, and shared workspaces. The extension also includes a Side Chat feature that lets users ask side questions without polluting the main conversation, a Prompt Optimizer to refine rough prompts before sending, and conversation notes and timestamps. Its rendering approach only draws elements near the user's viewport, which reportedly keeps long conversations smooth and responsive. GPT Master is featured on the Chrome Web Store with a 4.8-star rating from over 190 reviews and is used by thousands of weekly active users. GPT Master was created to address common ChatGPT pain points such as cluttered sidebar, laggy long threads, and difficulty finding past chats. It positions itself as a 'power toolkit' that enhances the native ChatGPT interface without requiring a separate account or signup. All data remains in the user's ChatGPT account and local browser profile, as the extension only requests access to chatgpt.com and Chrome storage.
