Description

Capacities is a note-taking and personal knowledge management app that structures everything you capture—people, books, projects, ideas—as connected objects with properties rather than flat pages in folders. Objects link to each other to form a knowledge graph, with backlinks and automatically surfaced related content revealing connections between notes. It also includes an AI assistant that writes, summarizes, and surfaces links between objects, and centers daily notes as a low-friction inbox for capturing thoughts.

Thea is an AI-powered study platform for students that converts uploaded materials — PDFs, slides, docs, images, audio, video, and YouTube links across 90+ file types — into flashcards, summaries, study guides, and simulated tests. Built on cognitive-science methods like active recall, spaced repetition, and a Socratic 'Smart Study' mode, it asks you questions rather than handing over answers, positioning itself as a learning aid rather than a cheating tool. It's free for the vast majority of students (90%+ never pay), supports 80+ languages, and is aimed at exam prep for school, AP/IB, and standardized tests.
