About CaptureNote

CaptureNote is an AI tool designed to convert screenshots, lecture slides, textbook pages, charts, and diagrams into structured notes. Users upload an image, which is processed to extract summaries, key points, and terms, then saved in a private, searchable note library. The web version supports organizing notes with folders, editing, and exporting to Markdown. New web accounts receive 500 free credits, with additional credits available through paid plans or one-time purchases. A separate iPhone app offers offline, on-device processing and Shortcuts integration, sold as a one-time purchase. Web and iPhone purchases are managed independently.
