What is Recall?

Recall is a personal AI knowledge base that saves, summarizes, organizes, connects, and lets you chat with your articles, YouTube videos, podcasts, PDFs, and notes. It provides answers from your own knowledge, the open web, or both, using the AI model of your choice, including ChatGPT, Claude, and Gemini. Beyond analysis, Recall enhances long-term memory using active recall and spaced repetition quizzes on a schedule optimized for retention.

How to use Recall?

Start by signing up for free on the web app or installing the browser extension. Save content from anywhere with one click, including articles, YouTube videos, podcasts, PDFs, and notes. Recall automatically summarizes, organizes, and connects your saved content into Recall Cards. You can then chat with your knowledge base, use augmented browsing to see connections, and generate quizzes for spaced repetition.
