Cons

Audio Overview generation can take several minutes for large document sets, and the conversational format occasionally oversimplifies nuanced technical content.
No real-time collaboration features, so teams cannot simultaneously work within the same notebook or share AI-generated insights in a live session.

Complex or highly nuanced queries can occasionally be misinterpreted, leading to answers that miss the specific angle or context the user intended.
The free tier imposes daily limits on Copilot and Pro model queries, which can be restrictive for heavy researchers who rely on advanced features throughout the day.
While citations improve transparency, the AI may sometimes over-rely on a single source or miss authoritative references that a manual search would uncover.
