| Description | Obsidian is the powerful, private knowledge base that works on local Markdown files. With bi-directional links, plugins, and a beautiful graph view, Obsidian is the favorite of researchers, writers, and personal knowledge enthusiasts. | 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. |
