What is Twig?
Twig serves teams handling conversations with prospects. It answers phone calls, text messages and website chats, collects information, books appointments and transfers conversations to a person.
According to its documentation, Twig lets you:
- answer phone calls
- reply to text messages and website chats
- collect prospect information
- book appointments
- transfer a conversation to a person
We file it under Voice agents and phone, the category of tools to answer the phone with an AI, and it also overlaps with customer service and website chatbots. The category lists 11 verified tools on this site.
The publisher is Teamsync Software Inc., based in United States.
Who is it for?
It is mostly useful to these profiles: customer support, sales teams, and small business owners. The need it covers is simple to state: answer the phone with an AI.
Twig is a good candidate if:
- you plan to connect it to your tools or automations through its API
Before deciding, run a trial on a real task and measure the time saved: it is the only criterion that really counts.
How much does Twig cost?
Pricing model: paid. No permanent free plan is offered.
The first paid plan costs $49 per month (Sera Starter; 15-day free trial), according to the pricing page, checked on October 24, 2026.
Per month, that is close to the category median ($49 per month, based on tools with a published price).

Data and privacy
According to its privacy policy, data is processed in the United States.
For professional use, check that a data processing agreement (DPA) is offered, and do not send customers' personal data or confidential documents without one.
Exporting your content: JSON, CSV, PDF. Being able to get your data back makes switching tools easier later.
Three habits apply to every AI tool:
- turn off the use of your content for training if the option exists
- use a work account separate from your personal account
- review everything the tool produces before publishing or sending it
Platforms, languages and API
Twig runs on: web browser and API.
Interface languages: English.
A public API lets you call it from your own programs or an automation tool, and plug it into an AI agent.
