LazyPrep
Stop collecting study material. Start retaining it.
Most exam prep fails at retention, not access. LazyPrep turns certification prep into a system — structured courses with an obvious next action, flashcards and practice questions scheduled by the SM-2 algorithm, and timed mock exams whose mistakes feed straight back into your review queue.

Retention, engineered
Three ideas the whole product is built around.
It schedules your reviews.
Flashcards and practice questions run on the SM-2 algorithm — the same family Anki uses. Easy cards drift weeks out; fumbled ones come back tomorrow.
It practises like the exam.
Full timed mock exams, scored and reviewable. Every miss lands in a mistake notebook and is folded back into your review queue automatically.
It builds courses on demand.
Generate a structured course for any subject with your own AI provider key — encrypted before it touches the database, never returned to a client.
Everything it does
Runs in any modern browser and installs as a PWA on desktop and iOS. A native Android app (Trusted Web Activity) is in closed testing ahead of its Google Play listing.
Structured courses
Modules, lessons and checkpoint quizzes in a deliberate order — always an obvious next action instead of a syllabus to triage
SM-2 spaced repetition
Reviews schedule themselves; you never decide what to study next
Mock exams
Full timed attempts, scored and reviewable question by question
Mistake notebook
Every missed question is collected and folded back into the review queue

Any subject, your own provider key — encrypted with AES-256-GCM, never exposed to a client
