Instructorly
Step into a teacher’s day with up to 200 simulated students signing up, waiting, and joining 1:1 sessions back to back. Or practice a conversation with an AI voice partner.
Open the practice classroomOur not-so-secret ingredient
Some call it a sandbox. We call it the Test Kitchen.
A live, working demo of your idea, filled with simulated customers who talk back. It’s the kind of thing that used to cost too much to justify. Now it comes standard.
Pressure-test your idea before you ship. Practice real conversations with AI by voice or text. See it run on day one.
Try one nowWhy we don’t keep it a secret
A luxury most software teams never get.
Simulators used to cost as much as the product itself, so teams skipped them. They tested with whoever they could round up and hoped. The way we build has made a simulator an afternoon’s work, so now every real-time product gets one. It’s the ingredient behind how fast we move, and we’re happy to show you exactly how it works.
None of the ingredients are new. The recipe is. We combined them into something you can order at the window and be using minutes later, and most teams have never considered that a realistic thing to ask for.
How it works
From an empty room to a busy day.
01
Open the life raft.
Every product we build has a life raft menu: one place for help, training, and practice. The Test Kitchen lives there.
02
Set the crowd.
Choose how many simulated users you want, from a handful to hundreds. A red bar across the top shows you’re in practice mode, so nobody ever confuses it with the real thing.
03
Run the day.
AI drives the simulated users through the real product, the same code your customers will use, not a mockup. Talk with them by voice to rehearse real conversations.
One Test Kitchen, three jobs.
For the person deciding
“Show me it works before I bet on it.”
Watch a full classroom, a full race, or a busy day of customers play out on your own phone. No slides, no imagination required.
For the people using it
“Let me practice where I can’t break anything.”
Staff train themselves against realistic activity before going live. Nervous first-timers can rehearse in private.
For the people building it
“Let me test a full room, right now.”
Every change is checked against hundreds of simulated users before a real one ever sees it.

Race.radio
A simulated race is running right now. Watch runners move along the course and hear the announcer call them out as they pass each point. The app can’t tell them apart from real participants.

What it proves, and what it doesn’t
Simulated first. Field-tested second.
A Test Kitchen proves the product’s logic and experience under a full load. It can’t prove how a real phone behaves in a real pocket on a crowded network. So every product gets both: a simulation on day one, then a small real-world trial before launch. We’ll always tell you which one you’re looking at.
Simulated users are always labeled as simulated. We never present demo activity as real customers.
