OhMyMNAutoOCR
AutoOCR's primary job is to perform online corrections for foreign languages, which are automatically performed when excerpting. Formula recognition can only be called manually using MagicAction for Text and cannot be executed automatically at the time of excerpting.
Get API key
Like AutoTranslate, AutoOCR also uses a third-party service and requires you to obtain the key yourself.

Foreign Language Online Correction
TIP
Both Auto Execution on Excerpt and Language Recognition are valid for the current document so that they can be set separately for different documents.
MarginNote's OCR Pro does not support many foreign languages, making it impossible to excerpt properly, such as Russian (Supported now). AutoOCR uses Baidu's OCR service to correct excerpts online.
In combination with Autotranslate, auto-translation for foreign languages is also possible.
MagicAction for Text
Formula Recognition
WARNING
Formula recognition can only be called manually using MagicAction for Text and cannot be executed automatically at the time of excerpting. Do not select more than two lines of text, which tends to fail and will not be displayed completely on the card.
You need to use Markdown plugins to display formulas, so you must install Markdown plugins in advance. Currently, there are 3 Markdown plugins and I recommend using Milkdown.
This feature has three options
pure latex: MarkDown Please select this option for the plugins, including when Milkdown's MarkDown compatibility is enabled. Please note that the Milkdown and MarkDown plugins have different syntaxes for formulas. Please think carefully before choosing whether they are compatible.$$latex$$$latex$: myMarkdown and Milkdown are both viable options. You can check the differences between the two yourself if interested.
Please be prepared that although it looks cool, it is complicated to implement:
- Apply for Baidu OCR or MathPix API key.
- Fill it in AutoOCR and select the corresponding formula recognition service provider.
- Install any Markdown plugin and select the corresponding Markdown plugin.
- MagicAction for Text - in the pop-up menu for more options, turn on
Set as Commnet. - first select an excerpt or card (otherwise you can only copy the result to the clipboard), then drag to select, and click
Formula Recognition. The recognized Latex of the formula is automatically written to the previously selected card. Use the Gesture module to invoke the execution for a better experience.

Perform text recognition on the selected text or area and copy the result to the clipboard.
