About

Kess

Features
Read full description

Kess is a real assistant, not another chatbot. Ask out loud or type. She answers, then actually does the thing: calls it, books it, sends it, files it. WHAT KESS DOES - Makes real phone calls. The restaurant, the office, the shop, the plumber. She asks your question and brings back the answer. - Does things no app covers. Kess has her own computer: a web browser, files and small programs. Ask for something new and she works it out, then reports back. - Signs in to your own sites. Give her a login once and she keeps it encrypted, for you alone, and uses it only in her own browser. - Runs your calendar and reminders. "What's my day look like?" "Move my 2pm." "Remind me to send the offer by 5." - Sends your email and texts, written complete and ready. You see exactly what goes out and tap send. - Reads your mail. Gmail, Outlook and Microsoft 365. "Find the invoice from the plumber." - Starts your morning with a brief in her voice: your day, your reminders, the weather, what she is watching for you. - Orders your coffee and sets up rides, food, shopping and flights with your details filled in, one tap from done. - Makes real files: a budget, a deck, a document, a PDF, built and handed to you as a link. - Reads what you send her: photos, PDFs, spreadsheets and documents, right in the chat. - Talks hands free. Tap the mic once and have a conversation. In the car, she tells you what needs you. - Remembers you. Your people, your places, your usual order, and everything you told her today. FOR REALTORS - Showing feedback, done. After each showing she calls the other agent, asks the four questions, and writes it up for your seller. - Weekly seller updates every Monday, with showings, feedback and views, in a report with your name on it. - Online leads called within minutes, as your assistant, qualified and logged in your CRM. - "File this in Transaction Desk." She signs in through WEBForms, puts the document on the right checklist line and saves it the way the office needs. - Contracts filed: upload the deal and the price, deposit, conditions and closing date land in your CRM and calendar. - Rowan, your coach: a daily check-in, a Sunday call and your real numbers against your goal. Sold on top of any plan. PLANS Kess is free to try. Kess Pro, for one person, is CA$19.99 a month or CA$129.99 a year.

PRIVATE BY DESIGN You sign in with Apple or Google, and that is all Kess keeps: your name and email. Your calendar, contacts and reminders stay on your phone; Kess asks permission the first time she touches each one. Nothing is sent, posted, booked or paid without your tap. MADE BY ONE PERSON IN CANADA Kess is built and run by one person, a working realtor, in Canada. She grows new abilities every week, partly from what users ask for. Ask her for something she can't do yet and she takes it to the build room; you hear from her when it ships. Go live your life. Kess will take care of the rest.
