About Gradeless

The short version

• Gradeless is a set of short lessons — mostly math, with some reading, science, logic, coding and history — and a small arcade. Right answers earn seconds of game time; the arcade spends them.
• It's free, with no ads and no tracking. A child doesn't need an account to play. If they want one, it's a first name and a secret code, nothing more.
• Nobody picks a grade. A short warm-up finds where a child actually is, and the lessons start there.
• It's made by one person at Cornsnow LLC, with AI coding tools, and shaped by the families and teachers who press the Feedback button.

How a lesson works

Every lesson is a ladder of a few levels, and each level adds exactly one new thing: a bigger number, a helper taken away, a clock face instead of a table. The questions aren't written out ahead of time. Each one is made up on the spot from the level's rules and a random seed, so the same lesson is never the same twice, and a level that was hard can be played again with fresh questions. That seed is also the save point — it's in the address bar — so closing the tab and coming back lands on the very same question.

When an answer is wrong, the right one appears beside the question and stays there until the child moves on. Nothing pops up and vanishes. New ideas are taught before they're tested: a lesson about coins shows what a dime is worth before it asks.

Lessons that adapt

Lessons adapt while they run. When a level is easy, the child moves ahead sooner; when they're stuck, it steps back; every fifteen questions there's a short break. Every question has a speaker button that reads it aloud, in the device's own voice. Children who can't read yet hear each question automatically, and are never offered a lesson that needs more reading than they have.

Where you are, not what grade you're in

Gradeless never asks what grade a child is in. A warm-up of about ten questions finds a starting spot, and from then on the lessons themselves do the placing: every answer nudges an estimate of what the child can do, subject by subject, in tenths of a grade rather than whole ones. A single slip is never a strong signal. "Next up" on the home page aims just past that spot — about half a grade ahead — and reaches back when something didn't stick.

There are no letter grades and no leaderboards. Progress is shown as levels passed and facts learned.

Game time

Learning pays. A correct answer earns a few seconds of arcade time — more when the lesson is a stretch, less when it's review — and the child sees exactly that "+6s" the moment it happens. The arcade (Brick Breaker, Cake Climb, Star Lanes and more) spends the bank. The games are short and simple on purpose: the point is the trade. A child who has earned ten minutes of play has answered about a hundred questions.

Privacy

Because it's for children, Gradeless collects as little as it can: no last names, emails, photos or locations; no ads; no analytics companies. First names are stored encrypted, sign-in codes are hashed, and the usage record that helps us find confusing lessons is deleted after 180 days. All of it, with our notice to parents under COPPA, is on the privacy page — written in the same plain words as this one, and every sentence there is something the code actually does.

Who makes it

Gradeless is made by Cornsnow LLC, a small company in Wilson, Wyoming. There's no team page to show you. One person builds it, using AI coding tools to write much of the code, and the parents, teachers and children who press the Feedback button decide a lot of what gets built next — many of the changes on the What's new page started as one of those notes.
