Twig

Sera from Twig is a practical, instantly deployable AI receptionist that handles routine inbound queries, bookings, and lead qualification across voice, chat, and email. Its strength is in its simplicity: sign up, point it at your website and docs, and it's live in 30 minutes. The free tier lets you test the waters with 100 chats and 300 voice minutes per month. We'd reach for this when you're a dental office, auto dealership, medspa, or real estate agency losing after-hours calls to voicemail. Sera recovers those calls, books appointments, and integrates with your existing stack (Salesforce, HubSpot, Zendesk, etc.). The ROI calculator on the pricing page lets you estimate savings, which can be substantial if you're paying multiple receptionists. Where it bites: the volume limits. The Scale plan caps at 10,000 chats and 2,000 voice minutes per month—fine for most small businesses but restrictive for high-volume call centers. Overages ($100 per 1K chats, $1 per voice min) add up. Also, Sera is pre-configured, not a customizable chatbot builder—you can't tweak conversation flows from scratch. Compared to Intercom Fin, Sera is voice-first and doesn't lock you into the Intercom ecosystem. Against Decagon or Sierra, Sera's front-desk focus (booking, scheduling, multi-location routing) is narrower but deeper for its target use case. For enterprises needing on-premise deployment or very custom integrations, Twig isn't the right fit. In practice, Sera works well if your inbound is appointment-heavy and you need a quick, affordable 24/7 solution. But if you need deep technical support or handle 10K+ chats monthly, look elsewhere.
