The honest version

Real classics are hard. Most apps hand you the text and hope. Folio hands you the book's vocabulary first — so you don't stall on page 3.

How it works

Book-as-syllabus, in three steps

1

Pre-study the book.

Spaced-repetition flashcards for the ~600 words that cover 95% of the text — plus key grammar, idioms, and character names — chapter by chapter. Rate your confidence; Folio catches the words you only think you know.

2

Watch your reading power rise.

A per-chapter gauge fills as you study. It rewards real recall, not just exposure — so when it reads high, you genuinely are ready to read.

3

Read the original.

The unabridged text, with tap-to-translate and LibriVox narration. No abridgement, no simplification. Finish it and earn a completion card.

What you pre-study

Four pillars, all spaced-repetition

Folio catches the words you only think you know — and the structures that trip readers up.

A

Vocabulary

The ~600 words that unlock 95% of this specific book, glossed in context.

Grammar

The key structures and period constructions that trip readers up, taught before you meet them.

“

Idioms

Figures of speech that don’t translate literally — pre-loaded so they don’t stop you cold.

F

Characters & proper nouns

Names, places, and titles introduced up front, so the cast never blurs together.

FAQ

Questions, answered plainly

Is this a graded reader?
No. You read the full, unabridged original — the real text, exactly as written. Folio doesn’t simplify or shorten anything; it just prepares you for it first, so the original is within reach.
Are the books legal?
Yes. Every text is in the public domain, sourced from Project Gutenberg and Standard Ebooks. The narration is public-domain audio from LibriVox. Nothing in Folio is used without the right to do so.
Do I need an account?
No. There is no account and no sign-in. Everything — your progress, ratings, and settings — is stored on your device.
What languages are supported?
The texts are in English, with explanations, notes, and example translations available in six languages: Japanese, Simplified Chinese, Spanish, Korean, Brazilian Portuguese, and French. The English glosses are always the anchor.
How are definitions made?
Each book’s vocabulary is glossed with its in-context meaning — the sense the word actually carries in that passage — alongside a real example sentence drawn from the book itself.
