What is Open Research (oo.ai)?

Open Research is a South Korea-based AI search company founded in July 2024 by Il-Doo Kim, the former CEO of Kakao Brain, and it operates oo.ai, an AI search copilot. When you enter a query, oo.ai analyzes a large set of web documents, automates query refinement and cross-checks different web sources, then writes an answer, often as a structured report that reflects current issues and trends.

The service is offered on the web and as an app. It moved from a closed beta in October 2024 and an open beta in December 2024 to a full launch in March 2025, and the company reports passing one million monthly active users in April 2025 and two million in May.
