Teaching the way it has always worked — now with AI.
Good teaching has always begun with trusted texts and a teacher who knows the class. Classly keeps that intact — it just takes on the heavy lifting, drawn from the books you already teach.
Grounded, not generic
Not Generic AI.
Your AI.
Every quiz, slide and answer starts from your teachers' books — cited to the page — plus trusted open libraries like Wikimedia. Never the unfiltered web.
- Answers carry citations back to your text.
- No hallucinated facts from random websites.
- Stays inside the syllabus you teach.
- A closed environment — controlled inputs in, controlled outputs out.
In double circulation, blood flows through the heart twice in one complete cycle. Deoxygenated blood is pumped to the lungs, where it is oxygenated and returned to the heart before being sent to the rest of the body.
Generated answer
Blood passes through the heart twice — once to collect oxygen from the lungs, once to deliver it to the body.
Why it matters
The teacher time problem
A teacher's working week
Only 46% of the week is teaching.
Today's split is from teacher-workload research; the Classly split illustrates the prep time it is designed to reclaim.
Average work week — beyond contracted hours.
Of school time actually spent teaching.
Weekly prep & grading — the work Classly drafts.
Of teachers would adopt AI that halves grading time.
