| Description | Logseq is a free, open-source (AGPL) note-taking and personal knowledge management app built around an outliner and a bidirectional-linked knowledge graph, storing everything as local Markdown/plain-text files. It's aimed at researchers, students, developers, and privacy-conscious individuals who want full control and ownership of their data rather than a cloud-locked notebook. What most sets it apart is its local-first, plain-text foundation combined with a powerful query language and an extensible plugin ecosystem. | 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. |
