What is Side Space?
Research often leaves a browser full of useful pages and very little structure. The Side Space domain in the workbook now redirects to Side Copilot, whose current product brings browser organization together with AI assistance. It is designed around the pages already open: arranging tabs, working with their contents and keeping related work in spaces that are easier to return to.
Work with the pages in front of you
Side Copilot describes chat that can use the current page or open tabs for context, including summarization and extraction. Its agent mode can help manage browser tabs and windows, search history and support research tasks. Vertical tabs and topic-based spaces provide a visual structure around those conversations, so the browsing session has a place to live beyond a single answer.
Create a workspace worth reopening
For a product comparison, collect the official documentation and pricing pages into one space before asking focused questions. Keep the underlying pages available so you can verify an answer and revisit a source that changes. Features such as pinning, duplicate removal and tab suspension are useful housekeeping; the quality of the research still depends on choosing reliable sources.

Who is Side Space for?
People who research across many browser tabs and want an assistant alongside a more organized workspace, including analysts, founders and independent researchers.
Before you get started
Review extension permissions and supported browsers before installing. Confirm important summaries in the original pages, and keep confidential tabs outside the assistant unless your policies permit access.
