Why it sticks
Four decisions we made
so you don’t have to
Two answers, one undo
Knew it, or didn’t. No four-point self-rating to agonise over mid-session — and undo reverses the scheduling, not just the animation.
FSRS, not a fixed ladder
Intervals come from how your memory decays — measured per word, not per deck, and updated on every answer.
Offline, then synced
Study on a plane. Everything reconciles the moment you’re back, and a review counts once no matter which device recorded it.
Numbers with definitions
Retention, workload, what’s coming due — each stat says exactly what it counts, computed from your own history.
The scheduling
Eight right answers, and a word is 11 months away
Every answer updates a model of how firmly you hold that particular word. Get it right and the gap grows; get it wrong and it comes back inside the same session. You never choose an interval, and there is nothing to configure.
Phone and desktop
Twenty minutes, one thumb
Reveal, answer, move on. Put it down mid-session and pick it up on the desktop — same decks, same schedule, same place in the queue.
Everywhere
One account, one deck, one progress state
Answer a card on your phone on the train and the web already knows when you open it. Sync is not a paid feature and never will be.

Quick add - 02
Paste a list or a CSV
Preview every row before it becomes a card. All of it, or none.

Install a catalog unit
A ready-made deck you own outright and can edit like your own.
The catalog
Where Rayaad sits
Anki-level scheduling without Anki-level setup
Powerful spaced repetition without turning studying into system administration. One scheduler, already tuned. Two answers instead of four. Pronunciation and offline review built in rather than bolted on.
Anki
Same FSRS scheduling, already tuned. None of the deck options, note types or add-ons standing between you and a first review.
CompareQuizlet
Built for a session you start before a deadline. Rayaad is built for a queue that arrives and keeps the words for years.
CompareDuolingo
A course decides what you learn. Rayaad keeps the words you meet everywhere else — the ones no curriculum will ever reach.

Pricing
Start with 7 days of Pro
Every account opens on Pro for 7 days — no card, nothing to cancel — then settles onto Free, which keeps the entire learning loop permanently. Upgrade when you want more room and larger AI and speech allowances. Pro is not on sale yet, and nothing in the product collects a payment.
Free
The entire learning loop, permanently: FSRS review with no daily cap, every surface, full sync, offline, listen mode, the extension, stats, export. It stops growing at 500 cards — it does not stop working.
Pro
The same product with the ceilings removed: unlimited cards, unlimited language pairs, the whole catalog, and much larger AI and speech allowances.
