SnipNotes scans your notes automatically for several content types:

When SnipNotes detects such a content inside your note, it highlights the matching portion of the text and displays an appropriate icon next to your note.

Depending on the content type of a note, you can perform various Note Actions. For example, call a phone number or open an address in Maps.

If SnipNotes detects a wrong content type and e.g. erroneously marks your parcel tracking ID as a phone number, you can Turn Off Content Detection
