Grammarly is good at the grammar and spelling stuff but the deeper analysis is lacking.
Autocrit and Grammarly make a solid pairing as you can incorporate grammarlies tools with Autocrit for a full package. The same can be done with pro writing aid.
Autocrit is great for editing longer form text. It's less designed for short email and Slack threads. If you are writing a short story or novel it's fantastic. It can also be well used for longer form pieces such as articles and interviews. I would not personally use it to write my content in its first draft. It has a word editor but it's not as fully featured as your typical writing programs.
