We need a service with an API that quickly recognizes texts from a picture (pictures like scanned documents, that is, photographs of sheets with text). But the texts are specific, not just a set of words, but containing various special mathematical and not only symbols.
I'm currently using tesseract.js, but it's very slow (probably because OCR happens on the front).

Recommend a good OCR service that is not very expensive (up to $100 per month) and preferably has free trial tests.

There is a fairly good Yandex: https://cloud.yandex.com/docs/vision/concepts/ocr/
But there are nuances:
1. pay as you go billing, so it can be more or less than $100
2. it is not clear what with mathematical symbols - it may not be possible to process this completely automatically.
If you need to process complex documents a lot, then it makes sense to develop your own solution that will work well with your documents.
