Yes, the notes app in iOS 13 includes a built-in handwriting recognition feature. Although it does not correspond to any language/character type, it is possible to use it conveniently in a Japanese environment depending on the device.
The handwriting recognition feature of the Notes app refers to the use of the first line of text written in the drawing function as a heading. Sentences typed on the software keyboard automatically find the first line, but they are the same as the function.
However, automatic recognition is limited to some types of letters, such as alphabets (English/lowercase), Arabic numerals, and Kanji. Kanji are recognized with considerable accuracy, but hiragana/katakana is not covered, so kanamixed sentences are not recognized correctly. In the alphabet or Arabic numerals, parts considered to be second and subsequent are ignored.
Notes that are recognized as handwritten text appear as “Handwritten Notes” when they are listed, and handwriting appears as thumbnail images on the right edge. At first glance, you can see handwritten notes, so it can also be used to make your existence stand out.
Handwriting is treated as a shape, so the rest can be used as a regular note. You don’t need to write the entire note because you can include text, tables, photos, and other content you type on the software keyboard in the same note.
Recognized handwriting is searched. The search field of the “Memo” app, of course, spotlight search because it also becomes the target of the search field that appears when you flick the appropriate position down of the home screen, you can use it as a practical headline not only decoration.
Kanji and alphanumeric characters written in notes are automatically recognized and used as headings
