I built a visual dictionary that lets you point your camera at a real book and tap any word to define it

External resources

In this era of digitalisation and fast reward, it has become incredibly difficult to focus. When I used to encounter unknown words while reading physical books, I gave up looking for definitions (really) because I knew I had to google it, lose my focus and forget the word the next day.

So I built Piksi. Point your camera at any text, a book, a menu, a sign, and tap a word directly on screen (there is no scan then tap, no, you just tap live on screen with your finger the word you are looking at).

You get a contextual definition instantly without leaving what you're reading.

It recognizes the words next to it so that it knows if for the same word it's a verb, a noun, etc. It also gives you the definition in your native language if you're reading in another language.

You can also save words and build a personal vocabulary library, organized by source, word level, and date.

Available in 11 languages. Free, no ads, and Pro is currently free (you have to redeem it in the settings → Upgrade to Pro).

I will keep this free as long as I can sustain the costs.

Would love to hear what this community thinks, you're literally the people I had in mind when building this.

PS: The Android version is on its way :)
