Mnemo

Mnemo is a free, open-source desktop study application that bundles notes, flashcards, mind maps, and progress tracking into one local-first app. It is built with React and TypeScript on top of a local .NET backend, hosted in the operating system's native web view via Photino X. There are no accounts, no ads, and no tracking — your notes and study data live on your machine.

The notes module is a block editor designed for long documents, with rich text, math, code, images, callouts, columns, page links, tabs, and a draggable note tree. Notes export to Markdown, portable .mnemo packages, or PDF through a bundled Typst compiler. The flashcard module supports classic, cloze, and image occlusion cards with decks and folders, review scheduling through FSRS, and a separate self-graded test mode that does not disturb your review schedule. The mind map module runs on an infinite canvas with multiple layout algorithms, custom edges, frames, and export to PNG, SVG, or a Markdown outline. An Overview dashboard ties it together with widgets for activity, goals, memory, and testing.

Where paid study platforms like Quizlet lock your card sets behind a subscription and an account, Mnemo keeps everything local and portable: flashcards import and export through Anki packages, CSV, and .mnemo packages, and nothing requires a server. It covers much of the same ground as Notion (notes), XMind (mind maps), and Anki (spaced repetition) in a single offline-capable app. Mnemo is currently in beta (0.8.x), with Windows the most battle-tested build, macOS available for Apple silicon, and Linux shipping as a first preview. The interface is available in English, German, Spanish, Japanese, and Norwegian Bokmål, with light and dark themes and remappable shortcuts.
