Side Copilot

Side Copilot is an AI-powered browser extension designed to help users research, organize, and automate web tasks directly from a side panel. It caters to creators, productivity enthusiasts, and professionals seeking to streamline their browsing experience without disrupting their workflow. The extension provides a suite of AI-driven tools and tab management features to enhance productivity and web organization.

Key capabilities include an agent mode that automates browser actions such as grouping tabs, managing windows, searching browser history, and researching topics. The chat mode enables contextual interaction with open tabs, allowing users to ask questions, summarize content, select context, and extract information from current pages. Side Copilot also offers a vertical tabs manager, making it easier to scan, identify, and switch between open tabs, and introduces "Spaces"—dedicated areas for organizing tabs by topic, such as work, social media, shopping, or study, all within a single browser window. Spaces can be synced across multiple browsers and devices, including Chrome, Edge, Brave, Vivaldi, Sigma, Comet, Firefox, and Zen, by logging into an account.

Additional features include automatic tab syncing, customizable themes, multi-language support (English, Chinese, French, Spanish, Japanese), dark mode, tab pinning, fuzzy search, tab suspension to free memory, duplicate tab removal, and tools for saving or restoring tab groups. Users can copy all URLs in a space in various formats, move tab groups to new windows, and use Group Guard to auto-detect and group tabs by custom categories or domains. AI-driven grouping, bulk tab selection, and space management functions are also provided. The extension supports chat interactions with an AI copilot for tab management and offers autonomous AI agents for browser automation.

Side Copilot is available with a free tier that allows up to five spaces with cloud sync and basic AI chat capabilities. Paid plans provide unlimited spaces, advanced automation features, unlimited AI chat history, and additional tools for managing tabs, groups, windows, and browser sessions. Pricing is available on a monthly or yearly basis, with a pay-once lifetime option and free updates for life.
