Is a CRM That Provides Insight Based on Prospect Behavior Worth It?

I'm considering creating a micro CRM to track (complete journey & touch point) which content a prospect has interacted with on a website, via email, or through paid ads before they actually book an appointment or call (for SaaS or high-ticket items) on the website, or before adding a product to their cart (in the case of e-commerce).

Based on these interactions, this CRM would provide written insights (such as intentions, state, motivation, trigger etc.) for sales representatives to use during their calls, or it could automatically personalize or rewrite product pages if it's an e-commerce site.

Would you use this, and why or why not?
