Pros	Mid-conversation knowledge surfacing genuinely changes agent workflow speed Measured, third-party-verified ROI (Forrester 401% study) rather than only vendor claims AI spans the full support workflow (chat, voice, ticketing) rather than one channel	Flat monthly pricing avoids the per-resolution fee structures competitors use Founders' prior product experience (scaling to 100,000 users) lends practical credibility Playbook approach gives founders direct control over how AI responds to customers
Cons	Pricing isn't disclosed on the homepage Full "Gen-AI across every channel" capability likely requires higher-tier plans Voice AI Contact Center adds setup complexity beyond basic ticketing	No permanent free tier, only a 7-day trial $50-$200 monthly range may still be a stretch for pre-revenue startups Auto-resolution quality depends entirely on how well a team writes its playbooks
