Pricing without the tricks.
One sentence covers it: the review loop is free forever, and premium sells depth and speed. This page spells out exactly where that line sits, and which side of it you are likely on.

The model, in one sentence
Free shows the grammar, teaches vocabulary at a steady pace and gives you 15 drill questions a day; premium lifts the limits and adds speed. The core review loop is never the paywall: nothing you have learned is ever locked behind a timer, an energy bar or an ad.
That makes the free tier a real product, not a demo. A learner who keeps up their reviews can learn about 2,000 words a year on it, each with its stress, senses, cases and aspect, which is further than most paid apps take anyone.
What is in each tier
The full split. Nothing on the free list ever moves behind the paywall.
Free
The whole method, at a steady pace
- The full review loop: FSRS scheduling and unlimited review of every word you have learned, never capped, never behind a timer
- Up to 300 words in progress at once, with no daily limit on new words; a word frees its slot once it passes its six-week graduation check, so new words keep coming*
- The drills for cases, aspect, conjugation and verbs of motion: your first 40 drill questions free, whenever you start, then 15 a day
- Everything on the card: stress on every word, one card per sense, case brackets under every sentence, aspect pairs, declension and conjugation tables, tap-to-gloss
- Audio on words and sentences
- Ask AI: 10 credits a month, and reading answers that already exist is always free
- Progress and streaks, no ads, no energy bars, no lockouts
*How fast slots free up depends on how often you forget: a word you get wrong stays in progress a little longer.
Premium
Depth and speed for the serious run
- No cap on words in progress: start new words whenever you like
- Unlimited drills: as many cases, aspect, conjugation and motion questions as you want, every day
- Ask AI: 200 credits a month instead of 10, enough to take the deeper model to the hard questions
- Private questions: mark an Ask AI question private and other learners never see it
- And everything in the free tier, which never shrinks to make premium look better
Which side of the line are you on?
Stay free if you
- are building a steady habit and are in no hurry
- want real grammar on every card, stress, cases and aspect included, without paying for the privilege
- are still testing whether spaced repetition sticks for you
- are on a budget: the free tier is the same product, slower, not worse
Go premium if you
- have a reason to move fast: a move, a partner's family, an exam with a date on it
- learn new words fast enough that 300 in progress at once would hold you back
- want to drill for as long as you like, not 15 drill questions a day
- ask more than ten AI questions a month, or want to keep some of them private
So what does premium cost?
The split on this page is fixed: the review loop, the grammar display and the audio stay free, and premium sells depth and speed, not the basics.

Pricing questions, answered straight
Is the free tier really free forever?
Yes. The review loop is the product's core and it is never the paywall: every word you have learned keeps its schedule and stays reviewable, uncapped, with no ads and no lockout timers. The 300-slot capacity paces how fast new words come in; it never touches reviewing.
What exactly is the 300-word capacity?
It counts words in progress, the ones still being scheduled tightly because you could forget them. A word graduates when it passes a check review about six weeks after you first met it; it then stops counting and frees its slot. There is no daily limit on new words: you can start one whenever fewer than 300 are in progress. How fast slots free up depends on how often you forget.
What are Ask AI credits?
Every card and sentence has an Ask AI button for questions about the word or the grammar in front of you. A question costs 1 credit with the fast model and 5 with the deeper one; free accounts get 10 credits a month, premium gets 200. Failed answers are refunded automatically, and reading answers that already exist costs nothing for anyone.
How much does premium cost?
9.99 € a month, or 79.99 € a year, which comes to 6.67 € a month. The App Store and Google Play show it in your own currency. These are launch prices: they will rise later, and a subscriber keeps the price they signed up at for as long as they stay subscribed. The boundary does not move: everything listed as free on this page stays free, and premium sells depth and speed, not the basics. A founders lifetime plan at 149.99 € covers the Russian course for good.
Will free features ever move behind the paywall?
The commitments are public and simple: the review loop is never the paywall, the grammar display is never paywalled, audio is included free, and there are no ads on any tier. Premium exists to sell what free never promised: speed, unlimited drills, private Ask AI questions and a bigger AI allowance.
