Pros & Cons

Pros

  • Chat, email and voice agents run on one shared intelligence layer, so behaviour stays consistent across channels.
  • Agent workflows are written as natural-language AOPs, so support operations staff can define multi-step actions such as refunds.
  • Built-in A/B experiments, simulation testing and Watchtower QA support ongoing tuning at scale.
  • Large reference customers report results, for example 70% chat and voice resolution at Chime and an 80% deflection rate at Duolingo.
  • Reviewers on G2 rate it highly, with an average around 4.9 out of 5, and praise how quickly support responds.

Cons

  • There is no public pricing, so every quote needs a sales call.
  • Under per-conversation billing you pay even when the AI fails to resolve an issue.
  • Reviewers report an average implementation time of about two months.
  • Third parties describe helpdesk integrations as API-based rather than marketplace apps, and some reviewers mention missing features.
  • It is not suited to startups or small businesses.

Pros

  • Access to 40+ models from several providers in one interface, so teams can switch models without buying separate ChatGPT and Claude licences.
  • Strong EU compliance posture: ISO 27001 certification, a SOC 2 Type II audit, GDPR compliance and EU hosting on Azure.
  • SSO, SCIM and SAML are included even on the entry Core plan.
  • Non-technical staff can build no-code agents with their own knowledge bases and permissions.
  • Deployment options range from multi-tenant SaaS to single-tenant, bring-your-own-cloud and on-premise Kubernetes.

Cons

  • There is no permanent free tier, only a 7-day trial.
  • Dedicated and on-premise deployments require 2,000 to 5,000+ seats.
  • Reviewers say its workflows still leave many actions to humans, so automation of operational tasks is limited.
  • Building advanced agents has a learning curve.
  • Per-seat pricing with Max seat upgrades and workflow add-ons can get expensive for small teams.
