How does the "persistent memory" actually work?

SureThing.io's memory is a core AI architecture feature that allows it to retain and recall information from all your interactions.

Can I trust SureThing.io to communicate in my own voice?

Yes, developing an understanding of your unique communication voice is a primary function of its persistent memory. By analyzing your past emails and messages, SureThing.io learns your tone, formality level, common phrases, and stylistic preferences.
