Recall is an AI-powered reading and language-learning app. Open a PDF — yours, or one of the 668 books in the built-in library — tap any word you don't know to get an instant flashcard written from that exact sentence, and never forget it again.

The problem isn't finding new words—it's keeping them. You look up a word today and forget it by tomorrow. Recall captures the words you discover and locks them into your memory forever.

Read. Mark. Remember.
Open a PDF, pick a book from the built-in library, or paste a YouTube link into Listening Lab. Your files stay on your device—nothing is ever uploaded.
Recall reads the sentence around it and instantly builds a flashcard with the definition, grammar, and original context. One tap takes you back to the exact page it came from.
The card joins your queue, and Recall figures out exactly when you need to see it again. No streak pressure, no badges—when your queue is clear, you're done for the day.
Stuck on a difficult phrase or idiom? Instead of handing you a generic dictionary definition, the AI explains exactly what it means based on the context of the sentence you're reading.
A standard flashcard just asks if you recognise a word. Our drills challenge you in four different ways, transforming passive recall into active fluency.
Classic novels, short fiction and graded non-fiction — most of them narrated, with the transcript beside the audio. Every word you tap works exactly as it does in your own documents.
Recall uses a smart algorithm designed to lock new words into your long-term memory. Instead of reviewing everything every day, the app learns your pace. Words you struggle with come back often, while the ones you know get out of your way.
Every surface feeds the same deck and the same review queue. Nothing you collect ends up in a separate app.
Bring your own books, articles, or lecture notes. Tap any word you don't know, and it instantly becomes a flashcard linked to the exact sentence you were reading.
Paste a YouTube link and the transcript loads beside the video. Click a word and the card remembers which video, and which line, it came from.
A word you ran into with no page attached? Type it, pick a deck, and the definition, the examples and a visual cue are written for you.
A daily activity heat map, your memory strength, and a clear forecast of your next reviews—calculated entirely on your device, even when you're offline.
The web app is the whole product — it installs nothing and works offline once loaded. The Android build and the browser extension follow.
PDFs are opened and parsed on your own device. Only the single word you tapped and the sentence around it are sent — and only to write the card.
No ads, no advertising identifiers, no third-party analytics. The privacy policy names which AI provider processes which piece of text, and why.
Export every card you have made, or delete your account and every row of its data, from inside the app — no email, no waiting.
Free to use, offline-friendly, and everything you make stays exportable.
