Read anything.
Remember every word.
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 memorise it with spaced repetition (SRS).
Free · Works offline · No credit card
Read it. Tap it. Remember it.
The gap
You are already reading enough.
Reading happens in one place — papers, PDFs, subtitles. Memorising happens in another: a deck full of words you have never met. Between the two, words vanish.
I write the card while you read.

How it works
Three steps, then it runs itself.
Tap a word you don’t know
Recall reads the sentence around it and writes the card: definition, part of speech, an example, and the page it came from. One tap takes you back there.
Show up for a few minutes
The card joins your queue and the scheduler decides when it returns. No streak pressure, no badges — when the queue is clear, you are done for the day.
Page assistant
Ask questions about the page.
Stuck on a dense paragraph? The assistant already has the page you are on — no copying, no pasting, no second tab.
- Summarise the page, or unpack one hard sentence.
- Translate a phrase without leaving the reader.
- Have the page read aloud while you follow along.
Stuck on a page? Ask me.
Practice
Turn memory into instinct.
The review queue asks “do you know this word?”. The drills ask the same thing four other ways, so recognising a word turns into being able to use it.
- Multiple choice — recognise it among near misses.
- Matching — pair words with meanings against the clock.
- Fill in the blank — put it back in its own sentence.
- Speed round — answer before you can think.
Two minutes. Let's go.
Built-in library
668 books, if you haven’t brought one.
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.
- 668 titles, 578 of them narrated.
- Filter by level, theme, length or audiobook.
- Picks up where you left off, on any device.
Pick one at your level.
And the rest of the loop
Four more ways in — one queue.
Every surface feeds the same deck and the same review queue. Nothing you collect ends up in a separate app.
A real PDF reader
Continuous scroll, pinch zoom, highlighter and pen, sticky notes, bookmarks — and a jump straight back to the page any card came from.
Listening Lab
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.
Add any word
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.
Progress you can read
An activity heat map, retention, card strength and a forecast of what falls due next — computed on your device, offline, from your own review history.
The scheduler
It decides when. You just show up.
Recall runs an SM-2 spaced-repetition scheduler — the same family Anki users already trust. Each answer moves the card’s ease factor between 1.3 and 2.5, stretching or shortening the next gap. Weak words come back often; strong ones drift out of the way.
Four buttons. I handle the timing.

Privacy, plainly
Your documents stay yours.
The file never leaves
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.
Nothing is watching
No ads, no advertising identifiers, no third-party analytics. The privacy policy names which AI provider processes which piece of text, and why.
Leave with everything
Export every card you have made, or delete your account and every row of its data, from inside the app — no email, no waiting.
Questions
Before you start.
Is it free?
Yes — Recall is free to use, with no credit card and no ads. Sign in with Google or an email address and start reading.
Do I need my own PDFs?
No. The built-in library carries 668 books, 578 of them narrated — and Add Word turns any word you ran into somewhere else into a full card.
Does it work offline?
Yes. Your decks, review queue and statistics live on the device and sync as soon as you are back online. Generating a new card needs a connection; reviewing does not.
I already use Anki. Why switch?
Same scheduling family, none of the card writing. Recall generates the card from the sentence you met the word in — and one tap on that card returns you to the page it came from.
