About River
Summary
River builds an AI desktop for knowledge workers: a project-based workspace where users research, write, and produce finished work alongside AI across documents, slides, sheets, and a browser in one place. It replaces the fragmented workflow of juggling files across separate apps and chat tools that lack project context. The target user is anyone doing multi-step creative or analytical work who currently stitches together output from disconnected tools.
Business model
