You make the call. We tell you what to say next.
ColdCaller sits beside you on live calls, listens to the conversation and puts the next line on screen in plain English, exactly when you need it. No dialer. No robot voice. Just you, sounding like you know exactly what to say.
A call, start to finish
ColdCaller does not ring anyone for you and it never speaks. You stay in control of the call. The copilot reads the room and hands you the words.
Tell it the job
Your name, your company, what you sell and the one thing you want from the call. Thirty seconds of setup, once.

This demo talks to the same engine the copilot uses. Pick a prospect reply below, or type your own. What you see is generated live, not a canned script.

ThemWhat's this regarding?
Compliant cold calling is a feature, not a warning label
ICO rules allow most B2B live marketing calls, provided you screen against TPS and CTPS, honour objections, identify yourself, and keep your own do-not-call list. ColdCaller puts that discipline into the call itself.
ON AIR Identity, handled
When someone asks who is calling, the copilot returns a plain, honest introduction with your name, company and reason for calling. No dodging, no pretending.
INSTANT “Don't call again” means now
The moment those words land, the prompter switches to a stop selling line and the contact is flagged do not call. Not next week. In the moment.
QUIET Privacy by default
No call recordings. Audio stays on your device and is turned into text there. The server sees words, not voices, and keeps no transcript after the call ends.
Before you dial, have this straight
- 01Screen numbers against TPS and CTPS before calling (corporate numbers included).
- 02Keep your own internal do-not-call list and honour it across the whole team.
- 03Say who you are and which company you represent. Never hide it.
- 04If asked to stop, stop. Immediately, and for good.
- 05Handle any personal data you hear in line with UK GDPR.
ColdCaller is a calling aid. It does not replace your legal duties under PECR, UK GDPR or ICO guidance. Screening duties stay with you.

Questions people ask before their first call
Does ColdCaller make calls for me?
No. That is deliberate. Automated marketing calls in the UK need specific consent and most buyers hang up on them anyway. You make the call from your own phone. The copilot only listens and prompts, which keeps the call human and the compliance story simple.
Does it record my calls?
No recordings, by default and in the pilot. Your device turns speech into text locally in the browser, and the server works from that text. Nothing is stored after the call ends. If recorded calls ever arrive as an optional feature, it will be opt-in and off until you turn it on.
What do I need to run it?
A laptop running Chrome or Edge, a microphone, and your phone on speaker, like a normal call. That is the whole setup. It fits a home office, a car on hands-free, or any desk where you dial.
How fast is the suggestion?
Typically about a second after the other person stops speaking. The transcript streams while they talk, so the engine already has the context when they pause. During the pilot it is fast enough for real calls, and it is the part we tune most.
Will it sound like a robot wrote my lines?
Lines are short, spoken British English, written to be said out loud. You will still hear the odd clanger, because it is a model in a pilot, not a scriptwriter. That is why every suggestion is a suggestion: you read it, edit it in your head, or ignore it and say your own thing.
Is this legal under PECR and ICO rules?
The calling rules are about who you call and how you treat them. Live marketing calls are generally allowed for business numbers that are not on TPS or CTPS, where you identify yourself and honour any objection. ColdCaller helps you do all of that consistently. It does not do your screening for you, and it is not legal advice.
Where does my data go?
Speech to text happens in your browser. The text of the conversation is sent to our server and to our AI provider only to generate suggestions and your end-of-call summary. We keep no transcript afterwards. Full detail is in the privacy note.
Who builds this?
ColdCaller is built by Ultimate Vision Ltd, a UK software company. It started from a simple annoyance: cold calling is hard enough without also having to think of the next sentence while someone is talking at you.
Your next call can go better than your last one.
