Sera, built by Teamsync Software Inc. and marketed at twig.so, is an AI agent meant to replace a missed call or an unanswered chat with a resolved one. It answers across web chat, phone, email and SMS, books appointments, recovers missed calls, hands off to a human when needed, routes enquiries across multiple business locations, and works in several languages. The site cites 30+ integrations, cites resolving 70% of conversations with no human involved, and says it can go live within 30 minutes of setup, aimed at businesses such as clinics and service providers that lose business to unanswered phones.
An AI agent that answers real customer calls and books appointments needs a clear escalation path for anything urgent, unusual or high-stakes, and a business should test how it handles an edge case, such as a medical or safety question, before trusting it unsupervised. The company states SOC 2 Type II compliance, which is a specific, checkable claim rather than a vague security promise, though the 70% resolution figure and the 30-minute setup claim are the vendor’s own and will vary by how well a knowledge base is built out for a given business.
Free costs $0. Starter is $99 a month, Growth is $499 a month and is marked most popular, and Scale is $1,499 a month, with chat and voice allowances rising by tier from about 100 to 10,000 chats and up to 2,000 voice minutes a month. Overage is billed at $100 per 1,000 extra chats and $1 a minute for extra voice. Every paid plan starts with a 15-day free trial, during which the company sets up the phone number, knowledge base and booking integration, and a trial cancelled before it ends is not charged.
