PaperFlow: Digital Notebook

FUVEST, ENEM and UNICAMP in ink: Brazil's entrance exams, with the past papers solved inside the app. You write the answer as you would on test day, at your own pace or as a timed practice test. What you miss goes into your error notebook on its own and comes back for review — no spreadsheet, no copying questions over. Solving real papers and seeing your performance per topic is free. Plus adds each question's explanation, the AI schedule and sync across devices. START WITH THE EXAM Pick the exam and its date. Sign in with Apple, Google or e-mail in one tap, then answer three real questions in ink with the clock running. At the end, the summary: what you got right, what entered the error notebook and when it comes back. TODAY: THE COUNTDOWN AND YOUR STREAK One "Start" opens the day's session. The countdown to the exam, your question target and your Streak sit on the same screen. Two rest days every 30, milestones along the way and cards to share when you feel like it. GOT IT WRONG? IT COMES BACK TOMORROW The error notebook is a quiz: a question you missed comes back at growing intervals, and "Why did I miss it?" keeps the reason. Get it right three times and it leaves. Only your weak spots. PAST PAPERS, LIKE ON THE DAY The library keeps your place in every paper. Stop halfway, pick up where you left off. Build your own practice test from exams, subjects and topics — a whole topic or a single lesson. Performance per topic shows where you slip most. THE SCHEDULE UP TO THE EXAM Save the exam and the study plan is already there. With Plus, the AI orders the steps into a schedule that spreads reviews over your days, with an outline, cards and a quiz per step. Missed a day? It reshuffles itself. AND THEN, THE NOTEBOOK The same handwriting you used on the paper serves the rest of the subject. Select a handwritten passage and PaperFlow proposes cards and questions, with the answer and an explanation; you approve or discard each one. Circle a word, tap, and it becomes a link to another note. Wrote "prescription" in an October lecture? Type it and find it — search spans what you wrote by hand, typed and brought in as PDF, and your handwriting never turns into text unless you ask. YOUR PDF JOINS THE NOTEBOOK Import the handout, the syllabus, the paper. Write over it. Make cards and questions from a passage or the whole PDF; scanned pages are read too. Ask your notebook and the answer cites the page. PEN AND PAPER YOUR WAY The one that presses and thickens, the flex nib, the pencil that shades when you tilt, the fountain pen, the calligraphy pen, the highlighter. Ruled, grid, dotted and isometric paper. Covers you build. The stroke lands instantly and never pixelates when you zoom. YOUR FILES, ON YOUR DEVICE Everything stays as files on your device and works offline. The notebook is free forever. PaperFlow Plus has a 7-day free trial; cancel anytime in your store settings.
