Spaced repetition, minus the homework

You forget 70% of what you read. Recallie remembers.

Highlight anything — articles, books, PDFs, papers — and Recallie resurfaces it at the exact moment you're about to forget it. Five minutes a day. Lifetime retention.

Everything, remembered

A second brain that actually keeps its promises

Capture in one click. Review in minutes. Retain forever. Recallie handles the scheduling so you can get back to learning.

One-click capture, anywhere

Browser extension, Kindle sync, PDF upload, or a quick share from your phone. If you can read it, Recallie can remember it. Highlights are parsed, deduplicated, and filed automatically.

Reviews that take 5 minutes

A daily queue of 10–20 cards, tuned to your personal forgetting curve. Most people finish before their coffee cools.

FSRS-6 scheduling

The state-of-the-art spaced-repetition algorithm models your memory per card — not a one-size-fits-all timer.

AI-made flashcards

Recallie turns passive highlights into active-recall questions. Cloze deletions, Q&A, and "explain it back" prompts — generated, editable, yours.

Resurfaced in context

Reviews arrive with the original passage and source attached, so a half-remembered idea snaps back into focus. Weekly digests weave related highlights from different books into a single thread — that's where the connections happen.

Offline-first

Review on a plane, in the subway, on a mountain. Everything syncs when you're back.

The science

Your memory has a half-life. Beat it.

In 1885, Hermann Ebbinghaus measured how fast we forget: most of what we learn is gone within days. Spaced reviews — timed just before you'd forget — flatten the curve. Try it:

People keep what they read now

"I've read 40 books a year for a decade and could barely tell you what was in them. Six months with Recallie and I'm citing passages in meetings from memory. It's mildly unfair."
Maya Krishnan
Product Lead, Fieldnote
"Medical school is a firehose. Recallie's queue told me exactly what to review each morning and my practice scores went up a full letter grade. The algorithm just… knows."
David Okafor
MD candidate, Hexley University
"I was skeptical — another flashcard app. But the AI cards from my Kindle highlights are genuinely good, and five minutes a day is a promise it actually keeps."
Sofía Larenas
Independent researcher

FAQ

Questions, answered

How is this different from Anki?

Anki is a powerful flashcard tool — if you enjoy building and maintaining decks. Recallie starts one step earlier: it captures what you read automatically, turns it into cards with AI, and schedules reviews with the newer FSRS-6 algorithm. You get the retention without the deck-gardening.

Do I really only need five minutes a day?

For a typical reading habit, yes. The algorithm shows each card right before you'd forget it, so the daily queue stays small — usually 10–20 cards. Read more, and the queue grows, but reviews are designed to fit in a coffee break.

What can I import from?

Kindle highlights, PDFs, EPUBs, web articles via the browser extension, Readwise exports, and plain copy-paste. If it's text, we'll take it.

Is my reading data private?

Your library is encrypted at rest, never sold, and never used to train models. AI card generation runs on anonymized snippets, and you can export or delete everything at any time.

Can I cancel or get a refund?

Cancel in two clicks — your data stays exportable forever. Yearly plans come with a 30-day, no-questions refund.

Your next book deserves better than 20% retention.
