iOS app that detects LaTeX symbols from drawings. Built using PencilKit, SwiftUI, Combine and CoreML for iOS 14 and macOS 11.

Overview

DeTeXt

Finding the symbol you want to use in LaTeX can be hard since you can't memorize all the possible commands and packages for every symbol you might need to use in your document. 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 symbols that look like the one you drew, arranged in order of decreasing confidence.

  • Search the entire symbol set within the app, even if you only remember part of the name of the symbol and/or command. The app has 1098 symbols including all default mathematical symbols, and symbols from packages like tipa, amsmath, amssymb, textcomp and more.

DeTeXt was built using SwiftUI, PencilKit, CoreML and Combine.

Code used to generate drawings, figures and the image classification model can be found in the supplementary repository

    [Feature request] Copy command when clicking

    Love the app I am using it on MacOS and it works great, but it would be great to copy the command right away if you just click on it. Right now you have to right click -> Copy command and then you have it copied, a bit complicated :) The same would be great for the search view.

  • Drawings that are too small/too large are misclassified

    Drawings that are too small/too large are misclassified

    This happens because the point size becomes too small/large at certain scales, causing the classifier to be confused. Not sure what's the best way to solve this at the moment.
