Best for

Pick Sera by Twig if you're an SMB front desk losing leads to missed calls and want one AI to answer, qualify, and book across phone, chat, and email.

Skip if

Skip it if you need a deeply customizable enterprise voice agent with bespoke telephony routing, or full transparency about the underlying model stack.

Sera by Twig is an always-on AI receptionist that fields inbound phone calls, web chats, and emails for service businesses, qualifies the lead, and drops a booked appointment into your calendar. The agent ingests your FAQs, services, and policies, then handles common inquiries end-to-end before they ever reach a human, with PII detection and redaction baked in for regulated verticals.

Twig is pitched squarely at SMB operators in dental, automotive, real estate, med-spa, and sales teams who are losing leads to missed calls and slow email replies. Pricing is friendlier than enterprise contact-center AI: a free tier with no card, paid plans from $99/mo, and no annual lock-in. Self-serve deployment is advertised at roughly 30 minutes, which makes it a realistic swap for an answering service rather than a six-month integration project.

Integrations cover 30+ business tools including Salesforce, HubSpot, Zendesk, and Gmail, so bookings and transcripts can flow back into the CRM of record. The underlying model stack isn't disclosed, and depth of voice/telephony tuning versus dedicated voice-AI platforms is the main thing to validate in a pilot.

Editor's take

A sensible packaging of the AI-receptionist category for SMBs: voice plus chat plus email in one agent, CRM hooks, PII redaction, and pricing that undercuts most enterprise voice-AI suites. The 30-minute self-serve story is the real pitch; just verify call quality and escalation behavior on your own traffic before cancelling the answering service.
