An AI knowledge engine that answers questions about the world around you
Ask in plain language and receive a synthesized response instead of an unfiltered list of links.
Homepage prompts such as quantum computing, AI and job markets, or geopolitics give you an easy starting point.
A minimal layout keeps attention on your question and the answer, without dashboard noise.
Useful across science, technology, economics and current events rather than a single narrow niche.
A private AI search engine that answers in real time and shows its sources.
Search Mode pulls live web results and shows the sources behind every answer so you can check the reasoning yourself.
The engine states that it does not keep query logs, IP logs or search history, so your questions are not turned into a profile.
Switch between live web retrieval for facts and a conversational assistant for open-ended thinking without changing tools.
The interface mirrors a conventional search box, making it easy to adopt as your everyday starting point.
Real-time AI answer engine and research workspace combining live web citations with frontier reasoning models.
