Perplexity Spaces is Perplexity's collaborative research feature that turns AI-assisted research into a shared, persistent workspace. Teams can create spaces organized around projects, upload internal documents as reference material, and conduct AI research that draws from both the web and the team's uploaded files. The AI answers questions with citations, and every thread in a Space is preserved and searchable. Spaces members can build on each other's research rather than starting fresh each session. The combination of web research and internal documents in one AI-powered workspace addresses the fragmented nature of most research workflows. For teams doing significant research - competitive intelligence, due diligence, academic study groups, journalism - Spaces brings the depth of Perplexity's search into a shared collaborative environment.
