For families who want their kids to use AI, not lean on it
Every answer carries a link to the page it came from. Kids get used to clicking it, reading the sentence, and deciding for themselves whether the answer was right. That habit transfers to every AI they'll ever use.
Delyr answers from the books you've added before it looks anywhere else, so the help matches what they're actually studying. Over time those books become a library of your own.
A short course inside Delyr explains what the AI is, why it sometimes gets things wrong, how to ask a question that gets a good answer, and what to do when the answer is bad. Eight lessons, written for a middle-schooler.
Write my paragraph about why the Roman Republic became an empire.
I won't write it for you. I can explain the two main reasons historians give, from the pages here, and you can write the paragraph from that.
The Republic's generals gained armies loyal to them rather than to the Senate, and a century of civil wars ended with one man, Augustus, holding power [1].

Delyr answers questions only from the books on your computer, shows the page every answer came from, and refuses when it doesn't know. Your kids learn to ask well, check what they're told, and think for themselves. Nothing they type leaves the house.
Runs on the family laptop, Windows or Mac. No internet after setup. No account. Buy it once and it's yours; there is nothing to renew.
Every book you drop into Delyr becomes part of a library that's yours: searchable, quizzable, and on your computer only.
Most families already own the material that matters: the curriculum they picked, the readers, the workbooks, the science text, last year's projects. Drop them into Delyr and it answers from those before anything else, so the help your kids get comes from the books you chose, in the words their teacher, or you, would use. Ask about chapter four and it answers from chapter four. Quiz them on it and the questions come from that chapter, with the sentence each answer came from.
It grows with them. Add the next year's books and the old ones stay. Add their own essays and reports and Delyr treats those as a record of what they wrote, useful for review, never mistaken for fact. The result, after a few years, is something no online service can give you: a private library of everything your family has studied, that one of your kids can search at the kitchen table with the Wi-Fi off.
Takes PDFs and EPUBs, including scanned ones. Nothing is uploaded anywhere; the books never leave the folder you put them in.
A tool you can hand to a nine-year-old without a conversation about accounts, data, or what happens to the things they type.
"It told him it couldn't find that in the library and wouldn't guess. He went and found the chapter himself. That's the whole thing I wanted."What we're building toward. Real parent quotes will replace this line once families have used it.
No account. No internet after the first download. A log of every question on a parent page behind a PIN. You pay once; there is no subscription, no renewal, and no version that stops working next year.
No subscription, no renewal, no account that can be closed. The program and your library live on your computer and keep working for as long as the computer does. Windows 10/11 or a Mac with an M1 chip or newer, 8 GB of memory, 12 GB of free disk. The first download is about 6 GB; after that it works with the Wi-Fi off. If it doesn't run on your computer, you get your money back.
Yes, the way a good tutor does. It explains the idea behind a problem, shows a worked example with different numbers, summarizes a chapter, or quizzes them on it. It won't produce the essay, the paragraph, or the answer to the worksheet question. A parent can switch that rule off in Settings.
ChatGPT answers from what it remembers and can't show you where a fact came from. Delyr only answers from pages on your computer and links every answer to its page. It's a smaller AI, so answers are shorter and plainer, and it's honest when it doesn't know. Nothing your child types is sent anywhere.
A starting reference shelf: Simple English Wikipedia, Vikidia (an encyclopedia written for kids), and PhET science simulations, with Wikipedia and others available from inside the app. The library that matters is the one you build from your own books; Delyr also points you to publishers who give textbooks away free if you want more.
Yes. You pay $59 once and the program is yours on that computer. There's no subscription, nothing expires, and it doesn't need us to keep working. If we release an improved version, you'll be able to download it from where you bought it; nothing is ever pushed to your computer.
After the first download, yes, entirely. It connects to nothing on its own. The only time it uses the internet again is if you click Download on an extra library pack inside the app. You can turn off Wi-Fi and check.
There's a status page inside Delyr that checks itself and gives you a button for each fix. If it's still broken, email us and we'll fix the product.
