As a side note I wonder if this would even be a good captcha. Obviously most people would not be able to quickly solve it so bad start. But I think a computer could probably do pretty well in doing the actual selection. There are programs that use OCR/image recognition to translate math into latex code (see mathpix) pretty well. And I assume that testing if an integral is cognate improper would be fairly trivial to implement with some kind of symbolic solver program. I know captachas take clicking/speed/mouse movement into account to detect human input as well but this is a universal captcha problem. If you changed the problem definition for each captcha instance (change the desired integral property) then it would be harder for a computer as it would have to interpret the text into some kind of code for testing a function. Probably not impossible but by no means easy if there are even a few different kinds of problems.

I know it's possible for pdf's because I needed it. You can find some simple scripts for it that scrape pdf's as images. But with spreadsheets that wouldn't really work, you would need some type of OCR for spreadsheets. If I recall correctly mathpix can do that.

You can use MathPix (https://mathpix.com/) to generate LaTeX of screen grabs, and/or upload a whole pdf to convert it into LaTeX code (not always 100% correct, but mostly is). You get a certain number of screen grabs for free per month, and can also upload one whole pdf (under 10mb) for free too.

That's nothing like what OP's question is looking for.

Mathpix is a specialized OCR tool that when given an image of a formula returns LaTeX source code that (hopefully) generates a similar output.

Have a look at Mathpix Snipping Tool. It's an OCR tool geared towards equations, but it also features a lighting fast equation editor (used to correct mistakes on the OCR utility, but accesible without it). The free plan has a limitation on the ammount of OCR scans, but not on the editor usage. The only limitation of the editor is that it does not feature autocompletion (yet?).

You can use https://mathpix.com it allows you to take a picture of an equation or a table and it will convert it directly into latex code. It's really useful. Just make the table in a UI based editor like word or Google docs, then take a snapshot of it. And then you have the LaTeX code.

by using anki ... e.g. ankify relevant parts from https://en.wikibooks.org/wiki/LaTeX

maybe there are better places than this subreddit to find the best latex ressources?

(Instead of learning much latex) some use helpers like mathpix, some people use handwriting - mostly on their ipads into ankimobile but maybe there are add-ons?

For reference: what they use is MyScript which has an API and reasonable pricing.

I also had some success with MathPix as I demoed here: https://www.reddit.com/r/RemarkableTablet/comments/hl5znn/demo_of_remy_a_workinprogress_offline_app_to/ (look at 30')

A maior parte dos Professores que apanhei em Portugal usavam LaTeX. De qualquer das formas podes sempre enviar o PDF e ele que comente as alterações que quiser

Utilizar Word para qualquer trabalho científico parece tortura, especialmente para trabalhos académicos onde tens de citar uma data de documentos ou referenciar figuras. Para não falar de ferramentas tipo o Mathpix que te dão o código LaTeX a partir de uma imagem

Looks like https://mathpix.com/ does it. Don't know anything about it, just googled "LaTeX recognizer" based on a misty memory of an app I used to have on my phone that would recognize a handwritten character (I think it was Detexify)

I would use the mathpix snipper which both integrates with word and can be used in the wild taking snapshots from textbooks, problem sets etc. You get 50 free snips a month as a basic user or 100 if you have a student email. It's a great tool imo

My first idea was simply taking notes in your program of choice and then use an OCR to turn it into latex. I found this. I haven't tried it, but it seems to be a workflow that works.

Is using a mouse and/or keyboard is also difficult?

I'm not sure if it would help, but you could use a tool like https://mathpix.com/ to capture notes (of formulae, matrices, etc) from course materials, and store them in LaTeX or Word documents.

Donwload mathpix. It allows you to snip formula's and it converts it to latex format. But in the beginning I highly advice you to just write formula's by hand, such that you get a feel of how it works. Also don't be scared! Latex is not that hard and it makes writing documents really easy once you get the hang of it.

mathsnip uses the api from these guys https://mathpix.com where you also find phone/desktop apps for converting hand written equations to latex. You can probably snip a whole page of text and equations as long as you write neat and in the format of the journal you intend to publish in.

I use the same method, but I use VScode(I write everything in markdown + latex) and the extension VSNote, I'll give obsidian a try, seems a nice platform, thanks

I also use mathpix snip when I have a series of equation that will take too much time to write manually

I started doing that for my maths courses at university, it helped me a lot.

My approach was to skim the slides for the upcoming sessions for mathematical symbols, look them up on a list I found online that provides the name of the symbol, how to read them and how to get the symbol in TeX, furthermore I copied the example from the slides to the Anki card to give me some context how/where it's used.

I'd recommend to make a new Note Type tailored to your needs. If you wanna use LaTeX, taking hand written notes and want to speed up the card creation process you might find this tool helpful: Mathpix

Are you occluding the whole formula (e.g. the whole right side?) behind one big red square?

If so, you might be occluding too much at once.

When I anki a formula, I find it more useful to cloze out only one symbol, or a "semantically meaningful" chunk of symbols.

E.g. if you're learning the formula for the apparent brightness of a star, I would cloze out the numerator and denominator separately, since the numerator is the Luminosity of a star, and the combination in the denominator is the area of a sphere with radius d.

E.g. try this in a cloze card in anki:

[ {{c2::e_{Ti} }} = \frac{ {{c3::e_i}} }{ {{c4::\hat{\sigma}_{(-i)} }} \sqrt{ {{c1::1 - h_i}} } }]

Also make sure you know what each symbol means on it's own. What does the h sub i mean in the denominator? What does the sigma hat minus 1 mean *on its own*? (Its an estimate of the standard deviation when we exclude oberservation i), etc. It can be useful to make cards to explain each symbol.

E.g. "Q: what is e i in this formula? (include a picture of the formula, but not the text) A: it's the i-th residual, i.e. the difference between the real value yi and the predicted value y-hat-i."

Use MathPix to convert image of equation to mathjax. If the mathjax formula contains two braces next to each other, insert a space between them, otherwise anki thinks its a cloze.

Get https://mathpix.com for your computer.

I just open the hand-written documents through the remarkable app and select the part to turn into a latex equation with mathpix. Super easy!

I use a MacBook as well and reading and annotating pdf's is my primary use of the remarkable. I am very happy with how well this works. The software for removing and adding files is supreme. I was so happy with the cloud functionality, that I wrote software which converts any webpage into a pdf and adds it to my remarkable.

Regarding nib-longevity, I can't say I'm impressed. They last decently long, but the charging price for new ones is way too high.

I bought a refurbished one. The only difference I could tell was that the nib that was in the pen had been used.

f.lux and magnet, if you don't already use them.

Some kind of keyboard shortcut expander is great for typos, unusual symbols, and anything you have to retype often (links, email addresses, etc). At least on Mac, the default options for this are very application-restricted and stop working in many contexts.

Mathpix turns screenshots into LaTeX. Great for anyone writing and reading mathy things.

Tyke is a simple text box accessible from anywhere on your Mac. Excellent for making fast notes with minimal effort. (Doesn't preserve between shutdowns and restarts, though, so copy anything critical into a more permanent location.)

You can use Mathpix to get the Latex code from a screenshot.

​

`\begin{equation}`

`\text { b) } \rho_{n}=\left\{\begin{array}{ll}{n-1} & {\text { if } n \geq 1} \\ {0} & {\text { otherwise }}\end{array}\right.`

`\end{equation}`

Nel mio percorso da studente, ho speso innumerevoli ore a copiare a mano su LaTeX molteplici formule ed equazioni da libri, paper e manuali per una gran quantità di progetti e relazioni di laboratorio.

Per non parlare degli esaurimenti nervosi molteplici in periodo di tesi per riuscire a riportare tutta la teoria fondamentale in formato decente.

Ieri scopro l'esistenza di Mathpix, che letteralmente automatizza in due click quello che fino ad adesso sono state probabilmente settimane di lavoro da monaco amanuense.

E niente, sono in pieno meltdown isterico e sto cercando di capire a quale ente devo far richiesta per avere le mie ore di gioventù persa indietro.

OneNote ink to math does not work for me at all, too many recognition mistakes to be of any use IMO. I leave all my calculations in handwriting, but recently I started using https://mathpix.com/ snip tool to transfer some handwritten formulas to jupyter notebooks. The recognition is much better, but it does not continuously convert your notes.

this has been discussed multiple(many) times. There is not the one solution for everybody.

If you don't get answers that are enough for you I would search this subreddit and the official forum at anki.tenderapp.com

some ideas:

- check if you can get the file as html/epub/docx
- for converting also try outlook.com/office online or google docs.
- pdfs to latex formulas won't work, maybe https://mathpix.com/ ? or just paste screenshots.

Software for LaTeX / paper writing

I recently found this free desktop app that lets you screenshot an equation and gives you the LaTeX for it. It’s called Mathpix.

Overleaf is an online LaTeX editor kind of like Google docs, where you can have other people edit at the same time. It auto saves revisions (you can manually save too), and tracks changes (helpful for reverting changes). They have a half-price for students and some institutions provide it for free to their students/faculty.

I also use Mendeley to manage my library of papers/references. It’s handy because I can export a .bib file to use on my LaTeX file for citations.

If anyone has any other LaTeX related software recommendations, that would be great. I’m always looking to optimize my workflow.

I think this is what you might be looking for. I too am keen on building some sort of hand-writing to Latex model. Unfortunately, I'm, still working on my maths before getting to CNN's. But the rough idea is that combine with some sort of spaced repetition to make studying easier, as this is a problem that I'm currently facing. Shoot me a message if you're keen on bouncing ideas.

Mathpix is working on a Linux version of the desktop app now. There's also an iOS app where you can export the LaTex as a hack for now. The Windows and Linux versions should be released soon, stay tuned.
