Stop overpaying on bills you're already paying
Big companies train their reps to squeeze every dollar out of you. BillSlayer listens to your calls and tells you exactly what to say to get the rates you deserve.
Your phone company says:
“That's the best rate we can offer.”
BillSlayer tells you to say:
“I have a quote from T-Mobile for $40 less. Can you match it?”
They have scripts.
Now you do too.
Customer service reps are trained to protect company profits, not save you money. They know exactly what to say to make you accept their “best offer.”
BillSlayer levels the playing field. Our AI listens to both sides of the call and feeds you the exact responses that work - built on the same retention tactics, escalation paths, and discount programs the companies use internally.

Why negotiating actually works
Retention discounts, loyalty credits, and price-match programs already exist. Most people just never ask for them.
Retention departments exist to keep you
Losing a customer costs companies far more than a discount. Reps have offers in their system reserved for people who ask - or threaten to leave.
Competitor quotes are leverage
A real quote from a rival carrier or insurer is the strongest card you can play. We show you what competitors charge so you can ask for a match.
Knowing the playbook changes everything
Company-specific playbooks cover which discounts exist, which phrases get results, and when to escalate to a supervisor or retention team.

How does pricing work?
BillSlayer is $4.99/month after a 7-day free trial, plus a one-time success fee of 25% of your first-year savings when a negotiation works ($4.99 minimum, $199.99 maximum). Any month you save, that month's $4.99 is credited against the fee - so a winning month costs you nothing extra. If a negotiation doesn't work, there is no success fee.
How does the AI know what to say?
BillSlayer combines company-specific playbooks - known discounts, retention offers, and escalation paths - with real-time AI that listens to the conversation and serves you the response that fits the moment.
What if I hate confrontation?
Most of our users do! That's why we built this. You just read what's on the screen. The AI handles the strategy - you just speak the words. Many users say it feels like having a coach in their ear.
Is my data private?
Yes. Voice is processed on your device and never stored or recorded. Your bill info is encrypted. We don't sell data - we make money when you save money.
What about call recording laws?
BillSlayer doesn't record calls - we process audio in real-time on your device. However, about a dozen states (like California and Florida) require you to inform the other party when using call monitoring tools. We'll guide you through the disclosure process based on your state.
What bills can I negotiate?
Phone, internet, cable, auto insurance, home insurance, medical bills, credit card fees, car loans, mortgages, and more. If a human answers the phone, we can help you negotiate it.
When exactly am I charged?
The subscription bills monthly after your 7-day free trial. The success fee is charged only after you confirm the savings yourself - you'll see the exact amount, including your subscription credit, agree to it, and then your card is charged once.
What if the negotiation fails?
There's no success fee. Not every call ends in savings, and when it doesn't work out, the only cost is your $4.99 subscription - which is free any month you do win.
