What Notein is
Notein is an Android handwriting app for written notes and research PDF annotation. Its workspace supports an Infinite Canvas and A4 paper, with templates, colors, drawing tools, automatic shapes, and 3D shapes. PDF work includes split-screen viewing for multiple documents, recording while reading, and keyboard or stylus input. Note features include handwriting-to-text, outlines, annotations, bidirectional links, dictionary and translation tools, and file merging or splitting. Folders, cloud synchronization, and automatic or local backups support organization. Optional AI can create summaries, outlines, quizzes, flashcards, grading, OCR, Circle to Ask responses, and follow-up questions. AI runs when used, and selected content may be processed by Google Gemini; the policy says Google does not use it to train models. Files remain local unless AI, OCR, backup, or sync is initiated. Notein lists Google Drive, OneDrive, and Baidu Cloud Drive integrations. The free plan costs 0.00 USD and allows five notebooks; paid plans remove or change limits, with prices varying by location.
