Calibre
Platform: Runs on Windows and MacOS
Vendor: Kovid Goyal
Website: www.calibre-ebook.com
NGLS Expert: Kim Megahee
NGLS Notes: “This tool is great for creating a repository for your "best" copy or the production version of your doc or epub file. I use it also to create an epub book from my doc book.”

Grammarly
Platform: Web App
Vendor: Grammarly
Website: www.grammarly.com/plans
NGLS Notes: Similar in Function to ProWritingAid. Recommend you subscribe to Premium Level ($12/mo) for it to be useful enough for a pro-writer.

ProWriting Aid
Platform: Runs on MacOS and Web App
Vendor: ProWriting Aid
Website: www.prowritingaid.com
NGLS Expert: Kim Megahee
NGLS Notes: “There are several ways to use the tool, including a free version. My advice is, if you use MacOS, to use the first level (cheapest) subscription.”

Atticus
Platform: Web App
Vendor: Atticus.io
Website: www.atticus.io
NGLS Expert: Kirk Jockell and Mike Freeman
NGLS Notes: Note that the web address ends in "(dot)io", not in "(dot)com".

EmberWrite
Platform: Web App
Vendor: EmberWrite.com
Website: www.emberwrite.com
NGLS Expert: None so far. Kim Megahee has been talking to Micah McGuire (one of the founders). He says the tool appears to be powerful, but simpler than Scrivener and he will be participating in their KickStarter program.
NGLS Notes: Emberwrite is in beta testing now. If you have a new writing project starting up soon, it would be worth your time to join their beta test (if you still can).
EmberWrite is launching a KickStarter campaign soon (as of 6/16/25) and the price is expected to be a one-time, very reasonable fee. Participation in the KickStarter is likely to get a small discount.
Go to their website to see a short demo and find out more.

Living Writer
Platform: Web App
Vendor: Living Writer
Website: www.livingwriter.com
NGLS Expert: Kim Megahee
NGLS Notes: “Under further construction (adding new features all the time), but highly functional and useful in it's present state. I have a copy and have been experimenting with it.”

Scrivener
Platform: Windows and MacOS
Vendor: Literature and Latte
Website: www.literatureandlatte.com/store
NGLS Expert: Kim Megahee
NGLS Notes: “Scrivener is fairly complex, because it's very powerful. I suspect I'm only using about half of the features it has.”

Storyist
Platform: Web App
Vendor: Storyist
Website: www.storyist.com
NGLS Notes: No one within the NGLS has currently used this platform. However, research of this platform indicates that it's a competitor of Living Writer and Atticus.
