Check spelling as you type for macOS

Question

I spend many days trying to find an app for macOS that would check my spelling as I type and warn me with a sound that a word was misspelled. tinySpell+ is what I use on my PC and it is great. I with they will make the app for macOS as well.

Must have features that I am looking for:

• Checks spelling in any Windows application
• Checks spelling on-the-fly (alerts if the last typed word was misspelled)
• Checks spelling of text that is copied to the clipboard
• Allows you to add words to the dictionary
• Optionally beeps on error (beep sound can be easily set to any wav file)
• Optionally displays a spelling tip
• Opens replacements list with a simple mouse click or a hot-key
• Optionally copies the selected replacement word to the clipboard
• Optionally inserts the selected replacement word into the document
• Provides easy access to on-line web services (Search, Dictionary, Thesaurus, Encyclopedia)
• Easy Enable/Disable
• Uses little system resources

Nice to have:

• Allows you to specify applications for which tinySpell is disabled or enabled
• Supports Hunspell dictionaries in many languages
• Remembers the last error (even if it is not the last typed word)
• Optionally displays a spelling tip with instant correction
• Includes a clipboard spell checker that shows all spelling errors in the clipboard's text in a single glance, and allows you to correct them
• Learns your spelling errors replacements and offers you better suggestions
• Allows you to add auto-replacements to the dictionary
• Allows you to add a list of words to the dictionary
• A scheduled Import/Export of the words added to the dictionary allows easy backup and synchronization of the dictionary with other users on a network
• Automatically switches dictionary according to current language (see Dictionaries below)
• Adds "Translation" to the on-line web services mentioned above (Search, Dictionary, Thesaurus, Encyclopedia)
• Allows you to easily choose the default on-line service in each category from a list of services, or add new services to the category
• Allows you to open a small bar on your desktop that lets you enter text and search for on-line information
• Provides the following additional options:
  • Check Capitalization (proper nouns, etc.)
  • Mixed CaSe is an error
  • Ignore UPPERCASE words
  • Ignore words with numbers
  • Ignore Internet & email addresses and file names
  • Ignore escape sequences (words that start with user specified escape characters)

I copied most of those features from tinySpell+ website. You could see examples there.
