Free AI study help for every American Grade 12.
General-purpose AI tutors (ChatGPT Plus, Claude Pro, Gemini Advanced) charge around $20 to $30 a month. Private American tutors charge approximately $100 an hour. Paid American study sites paywall most of their content. ExamExplained is free across the subjects and dot points we cover for AP, NY-REGENTS, TX-STAAR, FL-EOC, GA-MILESTONES, VA-SOL, TN-EOC, LA-LEAP, NC-EOC, MA-MCAS, OH-EOC, SAT and ACT.
Built by AI from the official College Board, NYSED, TEA, FLDOE, GaDOE, VDOE, TDOE, LDOE, NCDPI, MA DESE, ODEW, College Board and ACT syllabuses, past papers and marking guides. Free, forever. No signup. No email required to read the site. Anonymous error monitoring and aggregate analytics fire only to help us fix bugs faster.
Openly AI-built from official syllabus documents. Always check College Board, NYSED or TEA for current rules. How it's built →
Every page AI-built from public syllabus documents, past papers and marking guides. Not individually human-reviewed; always check College Board, NYSED or TEA for current rules.
How we built it
Openly AI-built and free, which is rare in the American study-resource market.
A frontier AI model reads public College Board, NYSED, TEA, FLDOE, GaDOE, VDOE, TDOE, LDOE, NCDPI, MA DESE, ODEW, College Board and ACT syllabus documents, past papers and marking guides, then drafts the library: dot points, guides and quizzes. Built on the same class of AI that paid general-purpose tutoring tools charge around $20 to $30 a month to access.
Hosting, model usage and the editorial work are all covered so the entire site can stay free, with no paywall and no signup.
No paywall, no signup, no chat. Static pre-built pages, ready at 11pm before a SAC. Anonymous analytics and crash monitoring only. Read the full methodology →
