What is Krog?
Krog is a place where your study material lives and is read well. Write or bring rich notes, quizzes, and diagrams on any topic — then study them until they stick.
What you can do
Study material that reads beautifully
Long-form notes with headings, a scroll-synced table of contents, callouts, tables, code, LaTeX math, diagrams, plots, timelines, and even molecules — all rendered cleanly and printable.
Study modes built for memory
Flashcards, timed tests, and reinforcement that prioritizes the questions you keep getting wrong — so your time goes where it matters.
Organized and shareable
Group quizzes into collections, share a link with your class, or embed a quiz in any website or LMS. Attach PDFs, images, drawings, and links to your material.
AI when you want it — not in the way
Generate a quiz or study material from a topic, or paste questions written by any chatbot you already use. AI is an on-ramp here, never a requirement.
Works offline
Install Krog as an app and download your quizzes and material to study anywhere — no connection needed.
Who it’s for
Krog is built and used daily by students. Whether you’re reviewing for an exam, sharing material with classmates, or just trying to remember what you read, it’s made to be the one place your studying happens.
Free for the core experience
Creating, studying, and sharing quizzes and material is free. Some AI and file features may become premium over time to keep the project sustainable — but the core will always be free.
