Memoar — Demo video

Memoar is an AI-powered personal knowledge library that turns scattered saved posts into organized, searchable, and useful information. People save tutorials, design inspiration, recipes, and ideas across social platforms, but rarely revisit them because traditional bookmarks lack context and meaningful discovery. Memoar solves this with a browser extension that captures content from supported social platforms in one click. Meta's Muse Spark analyzes visual and textual content to extract topics, keywords, objects, and contextual insights. Saved posts become part of a personal library where users can search naturally, explore automatically organized collections, discover related content, and revisit forgotten ideas. Built with a local-first approach, Memoar prioritizes user control without requiring a cloud database or account. Instead of saving more content and forgetting it, Memoar helps people rediscover what they already found valuable.
