How much does Sera cost?

Starter is $49/mo, Growth $499/mo, Scale $1,499/mo. Every plan starts with a 15-day free trial, voice included, no credit card and no contract.

How long does setup take?

Most businesses go live in under 30 minutes: paste your website so she builds the knowledge base, then forward your phone line.

What happens when Sera can't answer?

She doesn't guess. She captures the details and hands the conversation to your team with the full transcript attached.

What counts as a voice minute?

Any inbound or outbound phone conversation Sera handles end-to-end — answering, qualifying, booking or transferring — billed per minute. Hang-ups under 10 seconds are not counted.

What happens if I exceed my monthly limits?

Overages bill at $100 per 1,000 extra chats and $1 per voice minute. If you're consistently over your tier, upgrading is usually cheaper — Twig reaches out so you can decide.

When should I move to the Scale plan?

When you're multi-location, regularly blowing past 2,000 chats or 300 voice minutes a month, or you need a dedicated CSM, SLA and custom integrations.

Twig (Sera)

Twig builds Sera, an AI front desk that answers phone calls, web chats and texts around the clock. It qualifies callers, answers questions grounded in your own site content via RAG, books appointments straight to your calendar, and hands your team a clean intake summary with the full transcript. Missed-call text-back, live human transfer and multi-language conversations sit on higher tiers. Vertical playbooks ship for insurance agencies, dental practices, mortgage lenders, home services and B2B SaaS inbound sales. Setup is paste-your-website plus call forwarding — most accounts claim to be live in under 30 minutes. Pricing runs $49–$1,499/mo with a 15-day free trial; there is no permanent free tier. Best for local businesses bleeding revenue to voicemail. Skip it if you need self-hosted telephony or an open-source stack — this is closed SaaS, SOC 2 Type II, no public API beyond developer docs.

Core features

What it actually does

24/7 AI Receptionist (Sera)

Sera answers inbound phone calls, SMS texts, and website chat around the clock, handling the caller's questions and keeping them from ever hitting voicemail.

Appointment Booking

Sera qualifies the caller and drops the appointment straight onto your team's calendar, then texts confirmation and intake forms to the customer.

Missed-Call Text-Back & Human Handoff

Unanswered calls get an automatic text follow-up, and when Sera is out of her depth she hands off to a human with the full transcript instead of guessing.

Multi-Language Conversations

Handles callers and chatters in multiple languages on Growth and above, no separate setup or extra vendor required.

Industry-Tuned Qualification

Prebuilt flows for insurance, dental, mortgage, home services, and B2B SaaS — collects policy details, insurance networks, loan specs, or seat counts, and never quotes a price or binds coverage.

Technical capabilities

Website-to-Knowledge-Base Setup

Onboarding works by pasting your website URL to build the answer base, then forwarding your phone line. Twig claims most businesses are live in under 30 minutes.

SOC 2 Type II Compliance

Twig is SOC 2 Type II compliant, which matters if you're routing customer PII, insurance details, or financial intake data through the agent.
