How QuintaCapsa works

You write down a word and what it means. The app shows it back to you later - then again, spaced further and further apart - until it sticks. That is the whole idea

A word moves through five boxes

Every card lives in one of five boxes. The lower the box, the more often you see the card

↑ got it right → next box  ·  ✗ got it wrong → back to Box 1

• You add a word. It starts in Box 1
• Box 1 cards come up every day. Practise one as many times as you like in a session - get it wrong and it simply stays for today, so you can keep trying until it clicks
• Get it right and the card moves up one box. Now it waits longer before you see it again - 2 days, then a week, then 2 weeks, then a month
• Get a card wrong in any box and it drops straight back to Box 1. That is the point: the words you keep forgetting come around often; the ones you know leave you alone
• Answer a Box 5 card correctly twice and it graduates to Learned. It stops coming up for review. You can move it back any time if you want to practise it again

Answering a card

• Tap the card, or press space, to see the meaning. You do not have to - if you already know it, just answer
• Knew it: swipe right, press →, or tap Knew it
• Didn't know it: swipe left, press ←, or tap Didn't know
• Answered by mistake? Press z or tap Undo

Today's review is done when every card due has been answered correctly - a card you got wrong stays in the queue for the day

Topics and search

Give a card a topic - Spanish, Biology, Capital cities - and review one at a time. On the Boxes screen, the topic chips filter every box and today's queue together. Tap Manage topics to rename one, move cards between topics, select several at once, or delete a batch you imported by mistake

Search finds any card by the text on its front or back, also from the Boxes screen

Both work on every plan, signed in or not

Using it without an account

You can start straight away, no sign-up. Your cards are saved in this browser, on this one device - up to 26 of them. If you clear your browser data or move to another phone, they do not come with you. An export (below) is the only way to carry them across

With a free account

Sign in with your email - you get a one-time code, there is no password. After that:

• Your cards are saved to your account and appear on every device you sign in on
• They are backed up automatically as you go
• The limit rises to 52 cards

With Pro

Pro is $1.99/month or $18.99/year. Start it, or cancel it, on the Account screen

Import, export, and making cards with AI

Export writes all your cards and your full review history to a JSON file - a personal backup you can keep or move to another device. Import reads it back. Importing merges: it never wipes what is already there, cards you have since edited keep your newer version, and importing the same file twice changes nothing

Import also accepts a list of cards from somewhere else - a spreadsheet you exported to JSON, or a list an AI wrote for you. A bare array works, or an object that also names a topic:

{ "topic": "Spanish verbs", "cards": [{ "front": "…", "back": "…" }] }

The Import screen has a Copy a prompt button that writes the full request for you - say what you want after Notes for the AI:, paste the reply back into Import, and check the preview. The Topic there is pre-filled from the reply and editable, and every card in the batch is filed under it. Anything too long or a duplicate of a card you already have is flagged before it is added
