Questions before you try it

What readers ask before they photograph their first page.

Who is Legendo for?

People reading a hard book who get stuck on sentences: novels, plays and poetry, textbooks, philosophy and history, business books. And people reading in a language they're still learning. Legendo isn't an e-reader and doesn't summarise books for you: you read your own book, and it explains the lines you get stuck on.

Will it spoil the book?

It's built not to. Legendo knows how far you've read, and it's told never to use or hint at anything past your furthest page, even for a book the AI knows well. If a line can't be explained without a spoiler, it says the book hasn't covered that yet. The who's who works the same way: everyone in the book, as far as you've read and never further. It's AI, so if it ever slips, tap Report it under the explanation.

Can the camera read small, dense type?

Legendo reads the printed page from your photo; in a textbook, formulas come out typeset. Small type reads best when the page lies flat, in good light, and fills the photo: the app's camera finds the page's edges and takes the photo itself when it's steady. If a line comes out wrong, photograph the page again.

What happens to the photos of my pages?

Photos of your pages are read to text, then deleted: never kept, never sold. The text stays on your device, with your book; with an account, a backup is kept in it too. To write an explanation, the page's text (not the photo) goes to Anthropic's Claude; Legendo's server doesn't save it. Privacy says exactly what is sent where.

Is it free?

Yes, for 10 explanations, answers or catch-ups a day, with no account and no card. Legendo Plus gives you 40 a day, from $6.25 a month, and every plan starts with 7 days free if you haven't had it before. Prices has the details.

Which languages?

Explanations in six languages: English, Chinese (simplified or traditional), French, Spanish, Japanese and Korean, whatever language the book is in. Choose Learner for a book above your level, and explanations use simpler words and explain its idioms too.

How is this different from pasting a passage into a chatbot?

You don't type or paste anything: you photograph the page and tap the sentence. Legendo knows which book you're in and how far you've read, so it doesn't spoil what's ahead. It explains each kind of book in its own way: who's speaking and the allusions in a novel, the steps of a proof in a textbook, the argument in philosophy. And what you photograph stays with your book, for catch-ups after a break and for review.

How do I put it on my phone?

On an iPhone, open the site in Safari, tap Share, then Add to Home Screen. On Android, open it in Chrome, open the menu, then Install app. It opens full screen, like an app.
