Recall

Recall is a self-organizing personal AI knowledge base that saves, summarizes, organizes, and lets you chat with your content: articles, YouTube videos, podcasts, PDFs, and personal notes, all in one place. Get answers from your own knowledge, the web, or both, using the AI model of your choice, including ChatGPT, Claude, and Gemini. Related ideas are automatically connected in a knowledge graph and resurface as you browse, helping you discover relationships you'd otherwise miss. Beyond understanding, Recall strengthens long-term memory through active recall and spaced repetition quizzes, scheduled for retention. Used by 500,000+ people worldwide, including professionals at Bloomberg and Harvard, Recall is available on web, iOS, Android, Chrome, and Firefox. It combines Notion's editor, Obsidian's knowledge graph, NotebookLM's source-chat, and Perplexity's research depth, without the manual setup, source limits, or missing personal context. Recall turns your knowledge into your edge.
