About you

Your reading today

How often do you read books in the language you're learning?

Which apps or tools do you use today, for reading, dictionary, listening or review?

The honest part

When reading in your target language, what hurts the most? The top one.

And the second one?

What happens to the words you've looked up?

Have you used text-to-speech to listen while reading?

The pitch, then the number

We're building Sloth Reader: an e-book reader where you tap any word for its meaning, listen with a natural on-device voice that highlights each sentence, and every word you look up is saved with its sentence for spaced review. Everything works offline; your books never leave your phone.

What your answers shape: the page, the listening panel, the word card.

If this existed today, how likely are you to switch from your current tools?

What would you pay per year for this, if it delivers?

The one thing this app must get right for you to use it every day:

Only your email and answers are stored. Never your books, never your reading. No spam, one email when the beta opens.

Thank you.

Your answers go straight into what we build first. The lifetime launch deal is yours; we'll write when the beta opens.
