Keller: AI Assistant to Make Calls

Your AI phone assistant. One click calls the business on this page — books tables & appointments, negotiates, brings a transcript.

Keller is an AI phone assistant that calls businesses for you and gets things booked. You are already on the restaurant's page, the clinic's page, the garage's page. One click and the AI caller dials that business, waits on hold, books the table or the appointment, asks the questions you would have asked, and comes back with an answer. You never pick up the phone. Here is what happens when you click. The extension reads the page you are looking at, finds the business and its phone number, and shows you both before anything is dialed. You see the number in full international format, where on the page it was found, and how confident Keller is about the country code. If the page publishes opening hours you also see whether the place is open right now, and if it is closed you can schedule the call for the moment they open. Then you say what you want. Choose reservation and fill in party size, date and time. Choose appointment and give a reason, an urgency and a preferred window. There are templates for asking for a quote or a booking, and for chasing a support issue with an order reference. Or ignore all of them and write the instruction in your own words. Pick the language the call should be made in, from more than thirty, and press Call now. From there you can watch the call move from queued to dialing to talking, answer a question if Keller needs one thing clarified while it is still on the line, and read a plain summary and the full transcript when it finishes. You can play the recording, and jump straight back to the page the call started from. It works on the pages people actually look businesses up on: map listings, review and booking sites, directories, and the business's own website. Anywhere the page publishes standard business data or a clickable phone number, Keller can read the name and the number off it. In practice that covers most restaurant, hotel, clinic, dentist, salon, garage and shop pages. Privacy is the part that was designed first. Keller reads a page only when you ask it to, by clicking the toolbar icon, pressing Command Shift K, or right clicking a phone number you have selected. There are no site permissions in the install prompt and nothing of Keller's runs in the background on the sites you visit. If you would rather have the icon light up on pages where a business is detected, you can switch on auto detect in settings. Chrome asks for page access at that moment, the scan runs entirely inside your browser, all it ever reports back is how many businesses it saw, and switching the setting off unregisters it and hands the permission back. Every call opens with Keller saying that it is an AI assistant calling on your behalf and that the call may be recorded and transcribed. The extension gives you no way to turn that off. Keller needs an account and call credits from kellerapp.pro, and the call itself is placed by Keller, not by your browser. The extension is simply the shortcut: it turns the business page you were already reading into a phone call somebody else makes for you.
