How it works
A private assistant first, a phone assistant when you need one.
Trin gives independent professionals a practical assistant loop: talk from any device, capture what matters, and turn the conversation into memory and follow-up instead of another loose transcript.
Talk privately
Use owner-mode calls from web, iOS, or Android to test, brainstorm, and tune your assistant.
Forward calls
Let callers reach Trin through a dedicated number when you are ready for customer-facing phone answering.
Delegate calls
Let Trin call you with updates or place owner-authorized calls for tasks like reservations and appointments.
Keep the next step
Review summaries, notes, tags, and follow-ups after the conversation ends.
Your private owner assistant, already useful before a phone number.
Starter gives founders a private assistant they can call from web, iOS, and Android, plus incoming answering on an existing Twilio or Telnyx number. Founder Phone and Operator add a Call Trin-provided US or UK number and more voice minutes.

Frequently asked questions about Call Trin
What is Call Trin?
Call Trin is an AI phone assistant for founders and independent professionals. Trin answers your calls, takes notes, remembers your business context, and turns each conversation into a summary and follow-up tasks. You can also call her privately from the web, iPhone, or Android app. Call Trin is distributed by ILO APPLICATIONS SL.
How does Trin answer my calls?
Forward your calls to Trin, or give callers a dedicated number. She answers with the greeting, business knowledge, and boundaries you set, asks what the caller needs, and records the details. If a caller needs a real decision from you, she follows your escalation rules. Afterwards, you receive a summary of the call and any follow-ups.
Can I keep my existing phone number?
Yes. Keep your current number and forward its calls to Trin's number, or import a voice number you already own on Twilio or Telnyx. It stays yours, and that carrier bills its own number and call charges directly. Founder Phone and Operator can instead give you a Call Trin-provided US or UK number after payment is confirmed.
Does Trin say it is an AI?
Yes. Trin is designed to disclose that she is an AI assistant and never to pretend to be human. Calls from the public open with a notice that the call is recorded and processed automatically, and outbound calls identify Trin as an AI assistant calling on your behalf. Our terms require this disclosure.
Which languages does Trin speak?
Trin speaks in the caller's language. You choose the greeting language, English by default, and after the greeting she continues in the language the caller uses or asks for. We do not publish a fixed language list, so test your language in a private call first. The Call Trin website is available in English, Finnish, German, French, Italian, and Spanish.
How much does Call Trin cost?
Plans are billed monthly in euros. Starter is €29 with 100 voice minutes, Founder Phone is €79 with 300 minutes and a Call Trin-provided number, and Operator is €199 with 1,000 minutes plus advanced actions and outbound calls. A Custom plan is available for teams. If you bring your own Twilio or Telnyx number, that carrier bills you directly for it.
What happens after a call?
Each conversation is saved as a record with a transcript, a summary, the caller's name and intent, key facts, questions asked, promises made, and tags. Trin also creates follow-up tasks, so what needs doing waits in your follow-up queue. Email notifications are included on every plan, and SMS notification segments vary by plan.
How is my data kept private?
Owner and sub-owner memories are designed to stay separate from public caller conversations and from each other. Sign-in uses HTTP-only cookies with CSRF protection, and admin functions are role-checked. ILO APPLICATIONS SL, a Spain-based company, is the data controller under GDPR, and you can request deletion or export at support@calltrin.com.
