Knowt imports Quizlet flashcards before class. ExamGhost solves live Canvas exams in 0.3s.
Knowt (knowt.com) is an awesome free Quizlet replacement for studying flashcard decks and recording lectures days before a test. But many students install the Knowt Chrome Extension expecting it to solve live Canvas or Blackboard quizzes—only to find it only exports flashcards, forces you to switch tabs (triggering window.blur logs), and charges $24.99/month for Knowt Ultra AI.

Knowt vs ExamGhost: Frequently Asked Questions
Direct answers verified against Knowt.com and the Knowt Chrome Extension in 2026.
What does the Knowt Chrome extension actually do?
Knowt's Chrome extension is designed to import existing flashcard sets from Quizlet into Knowt with one click, and to summarize web articles, PDFs, or lecture videos into flashcard decks. It is not an in-tab LMS exam solver and cannot answer live questions inside Canvas, Blackboard, or Moodle.
Can Canvas detect if I switch tabs to search Knowt flashcards or Kai AI during a quiz?
Yes. Knowt has no Canvas Focus Shield or window.blur protection. Clicking out of your Canvas quiz tab to search a Knowt deck or ask Kai AI immediately dispatches window.blur and visibilitychange telemetry events, logging a red “Stopped viewing the Canvas quiz-taking page” entry in your instructor's log.
Is Knowt really 100% free in 2026?
Knowt's Basic plan ($0) offers free manual flashcards and Learn Mode (with ads), but heavily caps AI tools to roughly 1 AI summary and 1 mock exam per month. Unlocking unlimited AI summaries, Kai AI chat, and ad-free studying requires Knowt Ultra at $24.99/month or ~$149.99/year. ExamGhost offers 50 free AI solves ($0) and costs $19/month, $99/year ($8.25/mo), or $199 Lifetime.
Should I use Knowt or ExamGhost?
They serve two completely different stages of your semester. Knowt is an excellent free Quizlet replacement for importing flashcard decks, prepping for AP exams, and recording classroom lectures days before a test. ExamGhost is built for live, timed online exams and homework on Canvas, Blackboard, Moodle, and McGraw Hill Connect—where you need 0.3s Vision OCR and zero-blur stealth.
