Premium

Take a closer look at the answers.

You don’t need four subscriptions. ChatGPT Plus, Claude Pro, Google AI Pro and Grok cost $89.99 a month together. Premium is $8.99 a month and puts all four behind one search bar — with citations.

Cross-examine

In General Research, ask an independent AI model to review the compared answers against the same sources. See where models agree, where they conflict, and which claims the sources don’t back.

Citation checking

Check whether a cited page supports the claim made in an AI answer. Review supported, partly supported, and unsupported claims, with unreadable sources clearly marked.

These checks run when you request them. AI review can miss mistakes, and agreement is not proof — open the original sources to confirm.
