Meet Mendi, the AI reply assistant for X from Comment Verdict
Most replies add nothing. Mendi drafts ones that do: it reads the crowd beyond X, pulls in sources you can check, and hands you a reply with a point. A few good replies a day, not a hundred “GM”s.

How Mendi reads a crowd
Mendi brings together public discussion, current references and AI-assisted analysis to uncover useful ways into a conversation.
Comments from relevant videos reveal recurring reactions, questions and lived experience.
Related discussions add detailed arguments, community knowledge and competing viewpoints.
Public conversations broaden the mix with timely perspectives and specialist discussion.
Current external references ground factual claims. AI models compare, organise and connect the available evidence.
Open the source view to inspect cited comments, references and the wider pool behind a suggested angle.
Three approaches

Shared View

Different View

The interesting benchmark result this week is not the score, it is that three different labs converged on nearly the same number with completely different training budgets. That tells you more about the benchmark than the models.
