## Recognize text in math formulas

Hi,

I wonder if it's possible to recognize short, custom text-phrases in math formulas like "is prime" or "is even". I've seen that it's possible to define custom grammars, but so far I've not seen an example where this was used for text that includes spaces. Ideally, I'd like to get something like \text{is prime} as result.

In my usecase, I know all the possible text-phrases beforehand, so it probably wouldn't be difficult to bake them into a custom grammar file. I can also imagine I could just recognize "isprime" and insert the space myself later.

Thank you for any advice you can give me on this.

Dear Fabian,

thank you for contacting us and the interest you show to our technology.

As you have seen, our Math technology is indeed able to recognize latin characters. Nevertheless, it has not been tuned at all to recognize words, or sentences, and based on the tests we did for such purpose, it is not good at all for this purpose.

At present, recognizing words with the Math technology is not something we have in our plans.

Best regards,

Olivier

Many use Vim or other text editors because taking notes in higher level math classes is not supported by Nebo. I have experimented with Nebo attempting to do inline notes with symbolic math.  Even if I write latex inline such as  $\forall$ it fails to recognize the "\" and spaces "forall" to "for all" and it is more cumbersome to correct all the errors generated by the OCR.  Even "Real numbers" $R$ gets spaced out and as I am a slow typist it is quicker to retype the notes.  And, I am not saying Nebo isn't great for complex equations, it has saved me considerable amount of time.  It would be a nice feature, if Nebo would recognize LaTex start and LaTex end for all the short notes that you need to add inline such as $\tau$ defines a topological space . . .
