An ongoing memory would be very useful. From the product mentioned, and a blog post about their memory and advice feature (didn't know if posting a URL would be allowed):

Proactor is designed from the ground up to be a “second brain” that actively participates in your meetings. Here’s how it works:

It Builds a Memory: First off, every conversation you have is not just transcribed, but indexed and added to a “Global Memory.” This becomes your team’s collective intelligence.

It Detects Triggers: During a live meeting, its Insight Stream is constantly detecting triggers. These could be keywords, questions, specific topics, or even contradictions to things said in past meetings.

It Delivers Proactive Advice: When a trigger is detected, Proactor delivers its proactive suggestions. This can take many forms:

A fact-check: Correcting a misremembered statistic.

A contextual reminder: “Here’s the link to the document you discussed last week.”

A strategic suggestion: “You’ve mentioned ‘user churn’ three times.

Would you like me to pull up the latest churn report?”
