Folio — AI precision teaching
Taught to every gap.
Students write on ordinary paper. Folio reads every answer the instant it lands, finds exactly where each one slips, and turns that into the next lesson.
Book a demoThe magic moment
Graded the instant it's written.
Swiftly identify subtle knowledge flaws within seconds, providing detailed analysis instead of only marking answers incorrect.
Error notebooks
Every wrong answer, collected for you.
Each slip becomes an entry — by topic, by student, by how many classmates missed it. The reteaching list builds itself.
Smart classroom
See the whole class. Live.
Every answer the moment it's written: accuracy, pace, and the mistakes worth pausing on.
