LineHQ Pulse — your business line in your browser
LineHQ Pulse is a free Chrome extension for LineHQ customers. It puts your virtual number in the browser toolbar — a badge for unread activity, a desktop alert the moment someone calls, and today’s calls with their AI summary and caller sentiment — so you stay on top of the phone without keeping the portal open. It even warns you when a caller sounded unhappy or a matter was urgent.

Desktop call alerts
Get a desktop notification the moment a call, voicemail, receptionist message or text lands — no need to keep the LineHQ tab open.
Caller sentiment on your desktop
Each AI call summary shows the caller’s mood and how urgent it was. Priority alerts flag the callers who sounded unhappy, so you ring them back first.
Today at a glance
A “Today” pulse in the toolbar popup: call counts, a happy/neutral/unhappy split, the call-backs you still owe, and a low-balance warning.
Private by design, free to use
The extension talks only to your own LineHQ account with a token you create — nothing stored off your device, no third-party code. Free on every plan.

Frequently asked questions
What is LineHQ Pulse?
LineHQ Pulse is a free Chrome extension for LineHQ customers. It shows your business-line call activity — notifications, AI call summaries, caller sentiment and your account balance — in the browser toolbar, so you can stay on top of calls without opening the LineHQ portal. You need a LineHQ account to use it.
How much does the extension cost?
Nothing. LineHQ Pulse is free to install and use with any LineHQ package. You just need a LineHQ account and an API token, which you create in your dashboard under API tokens in a couple of clicks.
What are priority alerts?
When LineHQ transcribes a call or voicemail, it writes a free AI summary that includes the caller’s mood and how urgent the matter is. Pulse raises a priority desktop alert for callers who sounded unhappy or whose matter is urgent, so the calls that need a quick call-back don’t get lost in a busy day. No other UK virtual-number platform surfaces caller sentiment on your desktop like this.
Is my call data safe with the extension?
Yes. The extension only ever talks to your own LineHQ account over an encrypted connection, using a token you generate and can revoke at any time. It stores nothing off your device, contains no analytics or third-party code, and never sends your data to us or anyone else. Your call audio and transcripts stay on LineHQ’s UK servers.
How do I connect the extension to my account?
Install LineHQ Pulse from the Chrome Web Store, open its options page, and paste in an API token from your LineHQ dashboard (under API tokens). That’s it — your toolbar starts showing live call activity straight away, with nothing else to configure.
Which browsers does it work in?
Pulse is published on the Chrome Web Store and works in Google Chrome. It also runs in other Chromium-based browsers such as Microsoft Edge and Brave, which can install extensions from the Chrome Web Store. Dedicated Edge and Firefox listings may follow.
Do I get instant, real-time alerts?
Yes, optionally. Pulse checks for new activity in the background on a schedule out of the box, and you can switch on an instant real-time mode with a single toggle — nothing to configure — so alerts arrive the moment a call ends.
