AI can clone any voice in seconds. Here's what that means the next time your phone rings.

01 · Voice cloning

Cloned voices.

A two-second audio sample is enough. Your child's voice, your boss's voice — the scammer has both.

02 · Generated scripts

Generated scripts, voiced by AI.

Written in your dialect, aimed at your job, based on your LinkedIn.

03 · Mass dialling

Mass dialling.

One scammer now calls thousands per hour. The old defences can't scale with the attack.

01

Know who to trust

The community reports. Calmido warns you instantly.

When a number has been flagged — for scam, phishing, a callback trick, a silent call — you see it before you pick up. The faster a number gets reported, the faster everyone is protected.

02

See who's actually calling

Public data. Your contacts. Names only with consent.

Calmido Phone shows what's safe to show: company names from public business data, people already in your contacts, and registered users who've chosen to be visible. A private individual's name is never shown without their explicit consent.

03

Built on your side

Free. Your data stays with you. Independent verification.

Calmido Phone is free. Your contacts never leave your phone. The verification protocol behind Calmido is governed by TARIDE — an independent foundation Calmido doesn't control. Built in the Netherlands.

Names only with consent

Calmido Phone shows what's safe to show: company names from public business data, people already in your contacts, and registered users who've chosen to be visible.

A private individual's name is never shown without their explicit consent.

As the TARIDE protocol (an independent verification standard) comes online, organisations will be verified by trusted parties — telcos, chambers of commerce — confirming their numbers, their company registration, even their logo. That becomes the strongest signal yet.
