Recall
AI knowledge base that saves, summarizes and connects articles, videos, podcasts and PDFs into a graph you can chat with.
What it does
Recall is an AI knowledge base that captures articles, YouTube videos, podcasts, PDFs and notes in one click, then summarizes, auto-tags and links them into a knowledge graph. You can chat with your saved knowledge (or the web) using models like GPT, Claude and Gemini, with spaced-repetition quizzes for retention.
How to use: Sign up free at app.recall.it (no credit card required), add the Chrome or Firefox extension or the mobile app, and save content with one click. Recall summarizes and auto-tags it into a knowledge graph you can chat with, and generates spaced-repetition quizzes to help you remember it.
