## What is DeTeXt?

Finding the symbol you want to use in LaTeX can be hard since you can't memorize all the commands and packages for every symbol. DeTeXt tries to solve this problem by giving you two ways to find the command you want:

- Draw the symbol you want and DeTeXt's neural image classification engine will identify what it thinks are the 20 most likely LaTeX commands that will generate a symbol closest to the one you drew. DeTeXt supports Apple Pencil drawings on the iPad.

- Search the entire symbol set of 1098 symbols from packages like tipa, amsmath, amssymb, textcomp and more, in addition to the default mathematical symbols.
- Copy the symbol, or the character itself, or its Unicode codepoint to the system clipboard, to paste anywhere else.

DeTeXt's neural engine processes your drawn symbol and finds the best matches in its symbol database, all on your device without requiring you to be online. All the symbols are stored within the app as well.

## Key features

- Draw symbols to find LaTeX commands
- Neural image classification for symbol recognition
- Searchable database of 1098 symbols
- Supports Apple Pencil on iPad
- Copy commands, symbols, or Unicode codepoints
- Offline symbol database

### 5/5 — A great implementation of Detexify for iOS

*2022-06-04, version 1.4.3*

With DeTeXt, Venkata has leveraged the power of Detexity and brought it to a pretty and functional native iOS. app. This app works well, and very helpfully finds the LaTeX command for the symbols that you draw, saving a lot of looking up. I am very grateful for this.

## Frequently asked questions about DeTeXt

### What does DeTeXt do?

DeTeXt helps you find the correct LaTeX commands for symbols. You can either draw the symbol you need, and the app's AI will identify it, or you can search through a large database of symbols from various LaTeX packages.

### How does the drawing feature work?

You can draw a symbol on your screen, and DeTeXt's neural image classification engine will analyze your drawing. It then suggests the 20 most likely LaTeX commands that will generate a symbol similar to the one you drew. This feature supports Apple Pencil on iPads.

### What is the cost of DeTeXt?

DeTeXt is a paid application. There are no in-app purchases or advertisements within the app, meaning you pay once to access all its features.

### What symbols are included in DeTeXt?

The app includes a comprehensive set of 1098 symbols from popular LaTeX packages such as tipa, amsmath, amssymb, and textcomp, in addition to default mathematical symbols. All symbols are stored within the app for offline access.

### Can I use DeTeXt offline?

Yes, DeTeXt is designed to work offline. The neural engine processes your drawn symbols and the entire symbol database is stored within the app, so you do not need an internet connection to find commands.
