What Memex is
Memex is a private learning library for organizing and studying books, podcasts, videos, PDFs, and other documents. It brings these materials into one library, with notes that can link to an exact page, passage, or moment. Files can remain local or use iCloud Drive, and the library works offline; core use does not require an account. The complete app adds on-device AI transcription, read-along transcripts, study tools, folders, and export tools. Memex says it cannot access users' files, and its AI transcription runs locally on the device. Its privacy policy describes anonymous usage analytics and crash reports, but says analytics do not collect personally identifiable information; PostHog processes the anonymous analytics. Memex is available on iPhone, iPad, and Mac. Mac use requires macOS 14 or later and an Apple M1 chip or later. The Free plan costs nothing, while Study Monthly costs $4.99 a month. Eligible new subscribers can start a 7-day free trial. Support is available by email or Telegram, with a stated typical response within one business day.
