       | Mathpix is a great product that perfectly fills its niche and I'm
       | very happy it exists.
       | 
       | I wish some open source alternative existed. Even much less
       | accurate would be quite useful. I know latexify but it does only
       | single symbols.
       | 
       | Maybe it will be implemented as an extra language in tesseract
       | someday.

           | Wow, thanks! I had no idea it existed. I've searched for
           | something like it not that long ago.

         | A real one here, the tech is beyond expectations, the decoding
         | of equations is super, even of scanned sources. It only faults
         | at complex environments such as matrices or diagrams
         | (interpreted as cloud-URL to bitmap). It also OCRs surrounding
         | text. Couples nice with Typora Mathjax for an integrated
         | wysiwyg-markdown+latex experience.

         | conquered the Holy Roman Empire and the remaining part of
         | Europe if they had this software. I guess they understandably
         | didn't want to be tied to those characters.

       | Kind of unfortunate that a few of the demo pictures have a
       | binomial coefficient and the resulting latex code uses a
       | long/complicated array to express it rather than \binom. I'm not
       | sure I'd want to use this for anything I'll want to edit by hand
       | in the future.

         | When you use this it's usually because you don't want to
         | handcraft the latex to recreate an equation from another
         | source. It's unfortunate that it doesn't create the most
         | plausible form, because it would help when you want to edit the
         | equation but it's definitely not a dealbreaker.

       | I am very satisfied by their service, for an avid scientific
       | reader it is invaluable. Not only the output is good (it's mostly
       | right, only slightly more verbose than necessary, for example a^2
       | will be returned as a^{2}), but also the UX is excellent.
       | 
       | The only perk is that they significantly downsized their free
       | tier some time ago.
       | 
       | I think there are some papers with open source deep learning
       | models for this task but I never got to try one of them,
       | unfortunately.

       | Mathpix is great, but they have become much more restrictive.
       | 
       | I had an old version of this software which I think allowed for
       | unlimited snips but now I am limited to 100 for the free version.
       | Plus this is also a closed-source proprietary product. I will
       | look into the open-source alternative linked in this thread.

       | Mathpix did better than I expected, but still no-where near well
       | enough for me to give the results to anyone without some fairly
       | significant editing. It would certainly speed up creating a latex
       | copy of the paper, but for example whenever something has a
       | subscript and superscript, the superscript seems to be ignored.

         | yep, same hapened. You have to extract the pages of interest
         | before submitting, they have no page UI.

       | I used to use them two years ago when they offered 200 snip for
       | educational accounts. I then subscribed for personal plan for 5$
       | when I was writing my MS thesis. It was useful and make me write
       | quicker ( Still needed manual edits for most of the time). I then
       | cancel my subscription when they put a limit on personal paid
       | plan. Then they raised the prices of the (now limited) plan two
       | times in the last couple of months. They also moved the free plan
       | to be more of a demo. starting this month this ia their plans
       | 
       | Free Subscriptions: 10 Snips / month 20 PDF pages / month
       | 
       | Educational Subscriptions: 20 Snips / month 50 PDF pages / month
       | 
       | Pro Subscription: 5,000 Snips 1,000 PDF pages per month $7.99 /
       | month and $69.99 / year
       | 
       | I hope to see more competition in this field.

       | FWIW, pricing information was almost impossible to find on a
       | phone: you had to scroll all the way down on the particular
       | service page (eg. https://mathpix.com/ocr), so much so that I've
       | missed it originally.
       | 
       | There are no links whatsoever to the pricing, so only going back
       | and forcing myself to scroll through the entire page, did I
       | manage to find it.
