What happens on a browser test call?
You paste your web address. About a minute later she is built and waiting. The page asks for your microphone, you allow it, and then you speak to her out loud in the same tab, the way a customer would. No account, no card, no phone number anywhere.
She answers as your business, not as a demo. The services she names, the hours she gives and the area she says you cover came off your own website a minute earlier, so you find out at once whether she has your shop right.
A transcript scrolls beside the call, so you can see what she heard. Hang up when you have heard enough, fix anything that came out wrong, and call her again. Nothing is billable and nothing is live — no number is attached to her yet.
Nine other services are named further down. Every claim about them was read off that company's own site on September 2, 2026 — the same day the prices on our comparison pages were checked.
How do you get from a web address to a call?
Four steps. Only one of them asks anything of you, and it is a single click.
Paste your web address
Heyline reads the site and builds her from what it says. The promise is about sixty seconds; across 26 real business websites in our July 2026 test it averaged about 25 seconds. Nothing to fill in while you wait.
Allow the microphone
Your browser asks before anything starts. The page shows where the question appears, what to do if you miss it, and how to clear a microphone you blocked long ago. Refuse it and nothing is spent.
Talk to her
Press the call button and speak. Ask what your callers ask: whether you cover their street, what a call-out costs, whether anyone can come Saturday. Cut her off mid-sentence — being interrupted is handled.
Change something, then call again
Correct a service, an hour, a fact or her voice, then take another test call. Edits are in force on her next call, and re-testing costs nothing.
Decide with your ears — not a sales deck.
Paste your website and talk to your own receptionist, free, in your browser.
Can she book an appointment during the test?
No, and she says so herself. Your Google Calendar is not connected yet, so she pencils the slot in instead of writing it down: "I've penciled you in for Tuesday at 2 — connect your calendar to make this real." Everything up to that moment is the real thing.
The rest of the call runs on the same receptionist that answers a forwarded phone call, not a rehearsal version of her. She opens by naming herself as an AI and saying the call may be recorded — a disclosure enforced in code, which nobody can edit out. Asked something her notes do not cover, she takes a name and number instead of guessing, and she keeps an answer to a sentence or three.
Connect Google Calendar and the same request ends differently: she checks when you are busy, offers two or three real openings, books the one you pick, and reads the day, time, name and callback number back before she hangs up.
What a first test call sounds like
Sat · 9:40 AM — your kitchen table, two minutes after you pasted your website
Hi, you've reached Cedar Line Grooming. I'm their AI assistant — this call may be recorded. How can I help?
Do you take big dogs? And what does a nail trim run to?
Large breeds are welcome, yes. I don't have a price for nail trims in my notes and I won't guess — Elena can call you back with one.
Fair enough. Could I get a full groom Thursday morning?
Thursday at 9 AM is open. I've penciled you in for Thursday at 9 AM — connect your calendar to make this real.
That's the part I wanted to hear.
Nothing booked, nothing billed. Her opening line is the example greeting that rides on every call; the services and hours came off the site; the price the site never listed stayed unsaid.
Conversation is illustrative.
Can you talk to your own receptionist anywhere else first?
No — not on any of the nine competitor sites we opened that day. We went through all of them on September 2, 2026: the AI-first products Rosie, Goodcall, Dialzara, Slang AI, Sameday AI and Frontdesk AI, and the human-backed desks Abby Connect, Ruby and Smith.ai. Not one will let you hear a receptionist made out of your own website until you hold an account with them. It is a narrow claim, checked by hand, and the nuance under it matters.
Browser voice is not rare. Sameday AI's homepage opens a voice demo with nothing to fill in, and the developer platforms Vapi and Bland each put a click-to-talk agent on their homepage — in all three the agent is the vendor's own. Two more reach your own agent once an account exists: Smith.ai, whose free plan asks for no card, and Frontdesk AI, through an in-browser playground.
Every service listed is a real product, and the last column below credits each with something it does better than Heyline: Rosie hands a caller to a person, Abby Connect keeps humans behind the AI, Ruby and Dialzara move your existing number over for free, Sameday AI writes onto a dispatch board, Slang AI writes into a reservation book. The claim here is order, not quality: talk first, sign up after.

Frequently asked questions
Why does it ask for my microphone?
Because you are going to talk, not listen. A browser hands over a microphone only when you say so, so the page asks first, and it shows where your browser puts the question and how to clear a block you set long ago. Nothing starts until you allow it. There is no listen-only version — speaking to her is the point.
Is the test the same as a real call?
Almost exactly. It is the same receptionist your callers reach: she opens by naming herself as an AI, answers from what your website said, and takes a message when she does not know. Two things differ. She reaches you through your browser rather than a phone line, and a booking is penciled in, because no calendar is connected yet.
Can I test again after I change something?
Yes, and that loop is the point of the thing. Correct a service, an hour, a stray fact, her voice or the way she says a street name, then call her again and hear the difference. Changes apply to her next call. Anonymous visitors get a limited number of test calls; once you have claimed her and signed in, that limit no longer applies.
Does the test call cost anything?
No. Building her and talking to her are free, and no card is asked for at any point. Test calls are limited in number and in length so the line stays open for everybody, and at the limit the page offers to keep her rather than leaving you stuck. Paying starts when you go live on a plan, which needs a card.
Why not just call a demo number?
Because a demo number plays you somebody else's receptionist. You hear a script written for a business that is not yours, and learn nothing about whether she can handle your callers. In your browser she uses your business name, your services and your hours, minutes after reading them off your site. That is the question you actually have.
Hear her before you decide.
Paste your web address, allow the microphone, and ask her the question your callers ask. No account, no card.
