You feed it your knowledge sources — help docs, websites, FAQs, internal content — and it answers customer questions in your brand voice. On top of simple Q&A, it supports agentic behavior: chatbots that take actions, follow multi-step workflows, and operate with minimal human oversight.

The bot connects to the channels customers already use, including website widgets, WhatsApp, Instagram, and Facebook Messenger, plus Zapier for automation and knowledge sources for training. The platform ships with industry-specific templates for healthcare, SaaS, banking, retail, and hospitality, plus a white-label option so agencies and businesses can rebrand chatbots as their own. Enterprise plans are available for organizations that need stronger control and support. **Pricing & Plans:** Freemium with a free starting plan and paid tiers for higher usage and features; enterprise pricing is available on request.
