Veridian

Veridian is a 4-million-word knowledge base wired to an AI marking harness — 200+ documents, 40 to 65 per paper — more detailed than any resource I could find. It marks a full paper end to end: grade, UMS and AO breakdown, and confidence flags on every judgement.

I built it to study with, and it worked — it got me an A* and 98% in my own exams. Then I sold it: two schools and seventy independent students, all through cold outreach, zero ads.

Next it expands to the SAT, then more subjects, boards, and lower grades.
