Antinuous
Research service that takes a question, breaks it down, researches the answer and keeps the results in editable research sheets, drawing on the web and on the user's connected accounts, with recurring updates; its home page is a waitlist and its terms say it uses AI.

Antinuous AI agent
Research agent that takes a question, breaks it down, researches the answer on the web and in the accounts the user connects, keeps the work in editable research sheets with sources and history, and can run recurring updates until the user pauses them; the home page is a waitlist and no prices are published.
