Folioki

Learn a language through the things you read. Understand words in context, save what you want to learn, and remember it with spaced repetition.

Folioki turns reading into learning.
Learn a language through the things you actually read. Understand unfamiliar words in context, save the ones worth keeping, and remember them with spaced repetition.


Bring your own reading material to Folioki.

• Articles from the web
• PDFs and EPUBs
• Documents
• Text you add yourself Keep your library in one place and pick up where you left off on any device — your progress syncs automatically.


Hit a word or phrase you don't know? Select it for a translation without leaving the page. Need more than a translation? Ask Folioki to explain the meaning, grammar, or usage in the context of the sentence — a quick answer when that's all you need, a fuller explanation when you want to understand how the language works.

When you find a word or phrase worth learning, save it straight from the text. Turn it into a flashcard with everything that helps you remember it:

• Translations
• Example sentences
• Context from the original text
• Grammar and useful forms AI can create and enrich your cards, or you can write every one yourself. You're always in control.


Understanding a word once doesn't mean you'll remember it. Folioki uses spaced repetition — revisiting information at increasing intervals — to bring words back when it's time to review them. Words you find difficult get more attention. Less time on what you've already learned, more on the vocabulary that needs practice.

Instead of studying disconnected word lists, build your vocabulary from what you actually read. Every word you save carries context — it comes from a story, an article, a subject you were already interested in. Whether you're learning a new language, keeping one from slipping away, or simply want to understand more of what you read, Folioki connects reading, learning, and remembering in one natural flow.
