Microsoft Builds AI Debate Feature for Copilot

Microsoft is developing Copilot Advisors, a feature that pairs two AI personas to argue opposing sides of a user-chosen topic. Users pick from domain-specific archetypes – legal experts, finance specialists, traditional artists – and assign them affirmative or negative positions before the debate plays out, likely in audio with distinct voices. The format closely mirrors what Google did with NotebookLM’s Audio Overviews, where two AI hosts riff on source material in spoken dialogue. No launch date yet, and Microsoft hasn’t acknowledged the feature publicly. The underlying bet is that structured disagreement between agents is more useful for decision-making than a single model trying to present both sides, a design pattern that keeps showing up across products aimed at researchers and analysts.
