What is an equerry?
It's an old word for a trusted role: the attendant who held the details so their principal didn't have to. Here's where the word comes from, what it means, and why it became the name of a personal assistant who holds the details so you don't have to.
The meaning of the word
An equerry (pronounced ih-KWAIR-ee) is a trusted officer of a household responsible for someone's horses and, by extension, the logistics of their daily life. The word comes from the French écurie, meaning stable. In noble and royal households the equerry was the person who made sure the horses were ready, the travel was arranged, and the day ran without friction — a discreet, reliable aide whose whole job was to hold the details.
From the stable to the right hand
Over the centuries the role grew beyond horses. An equerry became a personal attendant and officer — someone who knew the schedule, remembered the obligations, anticipated what was needed, and quietly kept everything in order so their principal could focus on the work only they could do. The defining trait was trust: an equerry was given the run of someone's affairs precisely because they could be relied on to handle them well.
Why we named the product Equerry
That's the role we wanted to bring back. Equerry is a personal assistant in that tradition. You forward or CC the emails that matter, save a note, dictate a voice memo, or drop in a PDF or screenshot — and it remembers. Before your next client call it briefs you from what you've shared, and when you ask it something it answers with the source attached. Like the original equerry, it holds the details and keeps things in order — and you can see exactly what it remembers, and delete any of it, on a tap.
The modern equerry
Most people who'd have had an equerry once now have an inbox, a calendar, and more context than anyone can carry. Equerry is built for exactly that person — see who it's for among client-facing executives and management consultants, or how it handles meeting prep.
