About

Recall AI transforms the way you capture and retain information by turning scattered online content into a self-organizing, searchable knowledge base. Trusted by over 500,000 professionals and lifelong learners, Recall lets you save and instantly summarize any content — YouTube videos, podcasts, PDFs, Google Docs, articles, TikToks, and personal notes — with a single click via its browser extension, web app, or mobile app. Everything you save is automatically tagged, linked, and stored in a knowledge graph that surfaces hidden connections across your saved content in real time. The recently upgraded Graph View 2.0 lets you visually explore relationships between ideas and notes, turning passive browsing into active discovery. Recall's chat interface allows you to query your entire knowledge base at once using semantic and full-text search, so you can surface insights and see how ideas interrelate. Spaced repetition helps reinforce long-term memory by prompting you to review key content at scientifically optimized intervals. Privacy is a core principle: Recall never trains AI on your data, supports local browsing, stores your data securely, and lets you export everything at any time. With unlimited storage and support across web, mobile, and browser extension platforms, Recall is ideal for researchers, students, professionals, and anyone suffering from information overload who wants to finally stay on top of what they consume.
