Ultimo Bots

Voiceflow

by Voiceflow

Pros

• ✓Each agent combines playbooks, deterministic workflows, tools and a knowledge base, with separate development, staging and production environments, version history, persona-based tests and evaluations before changes reach customers.
• ✓Model choice per agent or playbook across OpenAI, Anthropic and Google plus Voiceflow's own Voiceflow Core model, with automatic fallback during a provider outage and a stated policy of no training on customer data.
• ✓Published customer results include Trilogy automating around 70% of support across 90+ products, eSnipe automating 70% of help center tickets and StubHub International launching 90 days from idea.

Limitations

• –Voiceflow publishes no list prices. Plan, seat and credit prices appear only inside the product after sign-up or through a sales demo.
• –The Free plan carries a one-time credit grant that does not renew, which Voiceflow describes as not suitable for production. Single sign-on and private cloud hosting are on Enterprise.
• –Live agent handoff connects to five named providers (Zendesk, Genesys, UJET, Kustomer and Dixa), with others added on request. Voiceflow-provisioned phone numbers cover the US and Canada, and Twilio, Vonage or Telnyx numbers can be connected.
