## What is DownWord?

DownWord is a new kind of AI deep-dive dictionary that lets you fully understand even the most difficult text, in fields you know nothing about, by breaking it down infinitely to your own level.

Use it whenever you run into jargon-filled writing: news articles, business books, or conversations with coworkers in unfamiliar fields.

[How to use DownWord]
First, paste in a word or sentence you don't understand.
Tap any word or phrase in that text that you don't fully grasp.
The AI will read the context and explain that word one level simpler.

If the explanation itself contains a word you don't know, just tap that word too and ask the AI again.

Repeat this until there are no unknown words left.

By the end, you'll find that the original sentence you started with suddenly makes complete sense.

Every word you drill into is laid out on a full mind-map view, so you can see the whole tree of understanding you built. Save it, or share it with others.

[Who it's for]

Anyone who wants to keep asking "What is that?" and "Why?" until they truly get to the heart of things.

Anyone who wants to learn the real nuance of words, not just their surface meaning.
