Last updated: 2026-09-30. Source of truth: https://calltrin.com (pricing at https://calltrin.com/pricing).

Call Trin is an AI phone assistant for founders and independent professionals. The assistant is named Trin. The product is built by Matti Vilola and distributed by ILO APPLICATIONS SL, a company based in Spain (https://iloapps.com). Support and privacy contact: support@calltrin.com.

## What Call Trin does

- Answers calls: forward calls to Trin, or give callers a dedicated number. Trin answers with the greeting, business knowledge, and boundaries the owner has configured, asks what the caller needs, and records the details.
- Optional Sensitive mode is included on every plan, including Starter, for incoming external calls, including anonymous test calls. When enabled, it directs Trin not to confirm or deny the identity of the business's owner or whether a named person is associated with it. It replaces the custom public greeting with a neutral greeting, asks the call purpose, and takes a message. Owner-authorized outgoing call tasks retain their supplied context.
- Escalates: when a caller needs a real decision from the owner, Trin follows the owner's escalation rules instead of committing on the owner's behalf.
- Talks privately with the owner: owner-mode voice calls from the web app, the iPhone app, and the Android app, used to set up, test, brainstorm, and tune the assistant.
- Makes owner-authorized outbound calls: Trin can call the owner with an update or place task-specific calls the owner has authorized, such as booking an appointment or handling a simple phone task. Outbound calls are on the Operator plan.
- Remembers context: saved services, pricing, FAQs, boundaries, owner preferences, and private owner memories.
- Turns conversations into follow-ups: each conversation can be stored with a transcript, summary, caller name and phone number, caller intent, key facts, questions asked, promises made, tags, and follow-up tasks with due dates in a follow-up queue.
- Supports sub-owners: an assistant can be shared with trusted team or family members, each with their own private memory and topics.
- Notifies the owner: email notifications on every plan and SMS notification segments (25, 100, or 300 per month depending on plan).

## Platforms

- Web app (browser), iOS app (iPhone), and Android app.
- Mobile apps link to the account with a short-lived QR or deep link from the signed-in web app; they do not ask for the account password.
- The mobile apps focus on one action: a direct owner-mode voice call with Trin. They show call readiness and play wait music during longer AI actions.

## Plans and prices

All prices are per month, in euros. Voice minutes are shared between owner calls (web and mobile) and incoming calls.

| Plan | Price | Voice minutes | Call Trin-provided number | Bring your own Twilio or Telnyx number | SMS notification segments | Sensitive mode for incoming callers |
| --- | --- | --- | --- | --- | --- | --- |
| Starter | EUR 29 | 100 | No (upgrade) | Yes, with incoming answering | 25 | Included, opt-in |
| Founder Phone | EUR 79 | 300 | Yes, one US or UK number | Yes | 100 | Included, opt-in |

| Custom | Talk to us | Custom | Reviewed per case | Reviewed per case | Custom | Included, opt-in |

- Founder Phone is the recommended plan for most users who want callers to reach Trin on a dedicated number.
- Operator adds a larger knowledge and instruction set, advanced Actions (webhook handoffs), owner-authorized outbound calls, export-ready notes, and an advanced follow-up queue.
- Custom plans are sales-assisted: custom included minutes, phone number and country support review, workflow and integration scoping, priority setup guidance, and optional invoice or contract terms.
- All plans include call summaries and transcripts, an assistant profile and voice setup, and email notifications.
- Sensitive mode applies to incoming external calls; it uses a neutral greeting instead of the custom public greeting, directs Trin not to confirm or deny the owner's identity or a named person's connection to the business, and asks the call purpose before taking a message.

## Phone number options

- Bring your own number: import an existing Twilio or Telnyx voice number on any plan. The customer keeps the number and pays that carrier's number and call charges directly. The Call Trin plan and its voice minutes still apply.
- Call Trin-provided number: on Founder Phone and Operator, after payment is confirmed, choose an available US or UK number that Call Trin provisions and manages.
- Forwarding: an existing business or mobile line can forward calls to the Trin number.
- A shared generic phone number is not the production model; each phone-capable account gets its own number.

## AI disclosure and safety principles

- Trin is designed to disclose that she is an AI assistant and never to pretend to be human. The terms of service require this.
- Calls from the public open with a notice that the call is recorded and processed automatically. Outbound calls identify Trin as an AI assistant calling on the owner's behalf.
- Trin answers from configured context, avoids regulated commitments and binding decisions the owner has not authorized, and escalates decisions that need the owner.
- Owner and sub-owner memories are designed to stay separate from public caller conversations and from each other.
- Call Trin is not for emergencies and does not replace legal, medical, financial, tax, or other regulated professional advice.
- Account owners are responsible for informing callers and obtaining any consent required for call forwarding, recording, transcription, or AI-assisted handling.

## Data and security

- Sessions use HTTP-only cookie authentication with CSRF checks for unsafe requests; administrative functions are role-checked.
- ILO APPLICATIONS SL (Spain) is the data controller for account, billing, product, and service data. Legal bases under GDPR include contract performance, legitimate interests, legal obligations, and consent where required.
- Optional call location: an owner can share a one-time approximate location during a web or mobile owner call for local weather or nearby places. It is used only for that call and is not saved as device coordinates in the conversation record or account memory.
- Data can be deleted or exported where the product supports it, or by contacting support@calltrin.com. Users may complain to the Spanish Data Protection Agency or their local supervisory authority.

## Languages

- Trin speaks in the caller's language. The owner chooses the greeting language (English by default); after the greeting she continues in the language the speaker uses or asks for. There is no published fixed list of supported languages, so test your language in a private call first.
- The Call Trin website is available in English (unprefixed URLs), Finnish (/fi), German (/de), French (/fr), Italian (/it), and Spanish (/es).

## Who it is for

Solo founders, indie developers, consultants, agencies, local operators, solopreneurs, and other independent professionals who lose time to calls they cannot answer, notes they forget to write, and follow-ups that sit half-finished.
