A patient tutor for your kid. Right on your device.
Cleophis lives on your computer — not in the cloud. It explains, step by step, as many times as your kid needs. Once it’s set up, tutoring needs no internet — and nothing your kid says ever leaves home. Ten dollars a month.
For Windows PCs with 4 GB of memory or more · Android on the way
Gentle help, whenever homework happens.
Endlessly patient
It explains again — a new way each time — without sighing, judging, or charging by the hour.
Works anywhere
Kitchen table, long car rides, spotty Wi-Fi. The tutor is on the device, so it just works.
One quiet price
$10 a month. No hourly rates, no surprise fees, and you can cancel whenever you like.
What happens at home, stays home.
Your child’s questions, homework, and conversations never leave your device — the tutoring has nothing to send. Your account is just a key: it signs you in, keeps each family member’s tutor separate, and manages your subscription. It can’t see what’s said. What happens between your kid and their tutor stays on the machine.
Conversations stay on-device · No tracking · A profile for everyone in the house
Downloaded, not streamed.
Most AI tutors live in a data center — your child reaches them through the internet, and their questions travel with them. Cleophis works the way software used to: you download it, and it’s yours. The tutor itself — the AI — is installed on your computer, sized to fit the memory it has. That’s why tutoring works with no Wi-Fi, and why the conversations never leave the house.
Questions travel to someone else’s computer.
The tutor lives on yours.
Their books, their notes, their tutor.
Cleophis isn’t just a chat window — it’s a private study space your family fills with its own materials. And like everything else, it all stays on the device.
Turn your materials into knowledge packs. The tutor answers from them and cites its sources — or says honestly when the answer isn’t in there.
PDFs, Word docs, EPUBs, text and notes — if it’s readable, it can join the library.
Keep chats organized by kid, class, or project — with search, and archive for when things pile up.
Export any conversation whenever you like. Nothing is locked in — because nothing ever left your device.
Built subject by subject — on purpose.
Each subject is its own specialist — a tutor trained for that topic, not a jack-of-all-trades stretched thin. The library keeps growing, and every tutor in it is part of the same subscription.
Tutoring, without the tutoring bill.
- Unlimited questions, 24/7

Questions parents ask.
What does it run on?
Any Windows PC with at least 4 GB of memory. Android is on the way, with more platforms after that.
Is it really private?
Yes — in the way that matters. The tutoring happens entirely on your device, and what your child says to the tutor is never sent anywhere. Your account only handles sign-in, family profiles, and billing — it can’t see the conversations.
Why is there an account?
Two reasons: it unlocks your subscription, and it gives everyone in the house their own space. Mom, dad, and each kid can have their own tutor, their own subjects, and their own conversations — separate and private.
Does it just hand over answers?
It’s built to teach — walking through problems step by step and checking understanding along the way, the way a good tutor would.
When does it need the internet?
To download the app, to sign in, and to add new subject tutors. The tutoring itself runs fully offline. And if you’ve signed in on a device before, it remembers you — you can get back in even without a connection.
What does it cost?
$10 a month, inside the app, after you install. Installing is free, and you can cancel anytime.
