Pros	$0.99 per resolution aligns the vendor with the outcome, not headcount Voice and messaging in the same product as chat and email Decision visibility rather than a black box	Genuinely native to a common B2B support workflow other tools don't address directly Fits naturally into how many SaaS companies already communicate with clients AI automation works within the existing Slack flow rather than requiring a new portal
Cons	Automation rate and accuracy are vendor figures with no stated method Per-resolution pricing gets expensive at high volume Resolution is defined by the vendor, not the customer	No free tier or transparent self-serve pricing Narrow fit for companies not already using Slack Connect with customers Less useful for consumer-facing or non-Slack B2B support needs
