New · Zynlo Books
Read it. Remember it.
Stories for adult learners in French, Spanish, German and Turkish, six books each from A1 to C2. Every new word is explained on the page, and comes with you into Zynlo as cards. Chapter 1 is free in every language.
Every day
Open Zynlo. Know what to study.
You should not have to decide which deck, and which cards, before you can start. Zynlo brings what needs your attention into one daily review.
One session, across every subject
Not one queue per deck. Zynlo gathers what is due wherever it lives, most overdue first, and you choose which subjects it draws from.
It tells you the size before you start
How many cards, how many are new, and roughly how long it will take.
And it has a limit
A daily allowance you set, so a week away does not turn into a thousand-card wall. What is left over says so.
Bring what you have
Bring your flashcards with you.
Switch without starting again. Your cards come across, and so does the work you already put into them.
Anki .apkg · .colpkg
Mochi .mochi
Quizlet copied text
CSV or TSV
Your review history comes too
An Anki package brings its images and its review log. Each past answer is mapped to Zynlo’s own scale by a stated rule, so a card arrives with its history behind it.
You see it before it happens
Every import is previewed: what would be created, what already exists, and anything Zynlo could not read.
And it says what it cannot take
Mochi’s image and sound files do not come across yet. Zynlo tells you on the way in, rather than dropping them quietly.
How it works
The test changes as you learn.
A card does not stay the same question forever. As it settles, Zynlo asks for more, and when you miss, it does something about it.
- 01
Flashcard
Read it, reveal it, say whether you knew it. A new card is never typed the first time.
- 02
Type it
Three right in a row, and the answer stops being shown. Now you write it.
- 03
Not quite
Miss it, and Zynlo says what happened. Here, the answer belongs to another card.
- 04
Repair
Where the card knows the mistake you made, you get that correction, not just a cross.
- 05
Retest
Then the same idea, asked another way, straight away, so you show you understood it.
- 06
Return
Back into the schedule, at the point where seeing it again is worth most.
Mistakes
More than right or wrong.
A wrong answer should not vanish the moment you tap next. Zynlo keeps what you actually wrote, and notices when it is a mistake you keep making.
It keeps what you wrote
The exact answer you typed, beside the one expected. Not a tally of right and wrong.
It names a mix-up
When what you typed is the answer to another of your cards, it says which one.
And it remembers the pattern
The answers you keep giving instead rise to the top of Today, counted from what you actually wrote.
You have the last word
When Zynlo marks a right answer wrong, “I was right” counts it, and can accept your wording from then on.
On Today
What trips you up
Pictures on cards
Put a picture on the card.
Some things are easier to remember when you can see them. A card can carry a picture on its question or its answer, and it comes back with the card every time.
On the question or the answer
Add a picture when you write the card, or later when you edit it.
Mathematics and formatting too
LaTeX set properly, Markdown, and answers that are a list or a sequence.
Your Anki pictures come across
An Anki package brings its images with it, and every backup keeps them.
Notes and photos
Snap it, note it, keep it on the card.
Notice something while you study? Add a note or a photo to the card in front of you, then carry on exactly where you were.
Take a photo, or choose one
On your phone, use the camera or pick from your photos. In a browser, upload a picture.
Your own words, beside the answer
A few lines of your own, kept with that card: where you heard it, what it reminds you of.
All in one place
Each subject gathers its notes and pictures on one page, so they are easy to find again.
They never move your schedule
A note or a photo does not change when a card comes back, and both travel in your backup.
Nine languages
Zynlo speaks your language.
The app is in nine languages. Choose yours in You, and change it whenever you like.

Right to left, done properly
In Arabic and Urdu the whole app reads right to left, and a French or Turkish card inside it still reads the way it should.
Your cards stay as you wrote them
Only the app’s own words change. Your study material is never translated.
For anything
One system. Whatever you’re learning.
Zynlo does not care what the cards are about. It cares whether you can still retrieve them in a month, under pressure, without the answer in front of you.

Progress
See what is actually sticking.
Every card is in one of four states, worked out from what you actually answered. Each word means one thing, everywhere in the app.
Holding
Right 3 times running, now typed
Settling
Seen, not yet 3 right in a row
Slipping
Wrong last time, and not a one-off
Not started
Not reviewed yet
Production accuracy
Your first typed answer on a card. A retry straight after seeing the answer is not counted, because it is not recall.
Needs attention
The cards and mix-ups that keep going wrong, each one a tap from the cards it counts.
Your library
Your learning belongs to you.
Years of work should not be trapped in an app, or lost because you chose the wrong one.
It lives on your device
Your subjects, cards and review history are stored where you study. Studying needs no connection: a flight, a tunnel and a basement are all the same.
No account needed
Sign in only if you want to. Signing in does not copy your library anywhere, and Zynlo sends your study material nowhere, except what an AI feature you choose needs, and only after you agree.
Take it out whenever you like
Back up everything as one file, export a single subject, and restore either.
Across your devices Coming soon. This page will say so when it works, not before.
One backup file
Everything you have learned
- Every subject and its settings
- Every card and its images
- Every review the part that took the time
- Your mistakes what you actually wrote
Questions
Asked, and answered plainly.
What is Zynlo?
A flashcard app built around retention. You create or import cards, and Zynlo decides what to show you and when, using spaced repetition.
Is Zynlo a flashcard app?
Yes. That is the whole product. The difference is what happens after a card exists: how it is asked, what happens when you miss, and when it comes back.
How does spaced repetition work?
Each review tells Zynlo something about how well you know a card. It schedules the next one for around the point where you would otherwise start to forget, so well-known material appears rarely and fragile material returns sooner.
Can I create my own cards?
Yes. A card needs only a question and an answer; explanation, hints, acceptable answers, common mistakes and a check question are all optional.
Can I import cards?
Yes. Zynlo reads an Anki package (.apkg or .colpkg) with its media and its review history, a Mochi export (.mochi), Quizlet material through its Copy text option, and markdown tables, CSV, tab separated text or JSON. Commas and quotes inside fields are handled, and so are accented characters.
Does Zynlo generate cards?
If you want it to: Generate with Zynlo writes cards from what you describe, using OpenAI, after you agree. Or Zynlo writes a brief for an AI assistant you already use, and imports what you bring back. Nothing goes to an AI service unless you use one of Zynlo’s AI features.
Can I use ChatGPT or Claude with Zynlo?
Yes, and that is the intended path. The brief is designed to be pasted into whichever assistant you trust.
What if Zynlo marks a right answer wrong?
Press “I was right”. The answer counts as right, marked as your call, and you can choose to accept that wording for the card from then on. Spacing, capital letters and missing accents never count against you in the first place.
Can I use it for languages?
Yes. Accented characters and non-Latin scripts are handled, so French, Turkish, Greek, Japanese and the rest behave properly, and an answer that is right but missing its accents is treated as a near miss rather than a failure.
Can I use it for medicine, law or exams?
Yes. Long questions and long answers are supported, and nothing assumes a card is a vocabulary pair. Please check anything that matters against an authoritative source: Zynlo does not verify imported material.
Can I use Zynlo on more than one device?
Not yet. You can sign in, with Apple, Google or an email link, but signing in does not copy or sync your library, so a library lives on the device it was made on. Moving it means exporting a backup and restoring it on the other device. Multi-device is being built, and this page will say so plainly when it actually works rather than before.
Can cards hold images or mathematics?
Yes. Images on the question or the answer, mathematics written as LaTeX and set properly, Markdown formatting, and answers that are a list or an ordered sequence. Images travel in your backups and come across from an Anki package. There is no audio: Zynlo neither plays nor records any.
Can I get my library back out?
Yes, at any time and without asking anyone. Back up everything as one file, which carries your subjects, cards, review log, settings and images, or export a single subject on its own. Both restore again. The review log is the part that took the time, so it is the part a backup exists to protect.
Does it work offline?
Yes. Your subjects, cards and review history are stored on your device, and studying needs no connection at all: a flight, a tunnel or a basement makes no difference. Nothing is waiting to sync, because there is nothing to sync to.
Is there a desktop or web version?
Yes. Zynlo runs in your browser at app.zynlo.app. Your library is kept in that browser only, with no sync, so export a backup from You now and then. Browsers can clear a site’s storage, and Safari may do so after seven days without a visit.
Which languages is Zynlo in?
English, French, Turkish, Italian, Spanish, German, Hindi, Arabic and Urdu. Choose yours in You, and change it whenever you like. Arabic and Urdu read right to left, and your own cards are never translated.
Do I need an account?
No. Everything works without one. Signing in with Apple, Google or an email link is optional, and it does not copy or sync your library: your material stays on your device.
Is it available for iPhone and Android?
Yes, both: Zynlo is free on the App Store and on Google Play.
What does it cost?
Nothing at the moment. There is no payment of any kind in the app and no pricing has been decided.
