What is Side Copilot?
Side Copilot is a browser AI extension that lives in your browser’s side panel and lets you research, organize, and automate the web without leaving your current tab. It works across Chrome, Edge, Brave, Vivaldi, Sigma, Dia, Comet, Firefox, and Zen. The extension operates in two primary modes: a chat mode for interacting with open tab content, and an agent mode that takes direct actions in the browser on your behalf. Tabs, windows, browsing history, bookmarks, and files can all be handled through the same side panel interface.

Real-World Applications
Keeping dozens of research tabs open across multiple projects can make it hard to stay oriented. Side Copilot’s browser AI can group those tabs automatically by topic, suspend the ones not in active use, and let you chat directly with page content to pull out the information you need, without opening a separate tool or losing your place.
Someone following a tutorial or working through documentation may need to cross-reference several pages at once. The multi-tab chat feature in this browser AI lets you ask questions that pull context from all relevant open tabs, cutting down the time spent manually switching back and forth to find answers.
Video-heavy research workflows can slow down considerably when content is locked inside long recordings. Side Copilot can summarize YouTube video transcripts and turn them into notes or mind maps, so key points from hours of footage become usable reference material without rewatching.
Writers and content teams working with AI-drafted copy can use the humanizer tool to rewrite generated text into a more natural style. Combined with the browser AI’s chat and tab organization features, it may fit naturally into a content production workflow that moves between source material, drafts, and reference tabs.
