Scrivener : Everyone know Microsoft Word. Scrivener is an alternative way to write, for authors (it works pretty well for me). The difference is that you can structure your work more easily.
Grammarly : It can be plugged in your internet browser, your Word, or even your desktop. With Grammarly, if you’re making a mistake, that means you’re doing it on purpose (maybe I exaggerate).
Hemingway App : I’m sure you know the writer Ernest Hemingway, don’t you? He had a particular way of writing sentences and had inspired a very useful little app to write simply. It will show you your “hard to read” and “very hard to read” sentences, your passive voices and adverbs.
On Writing by Stephen King : King is talking about his debuts as a writer, how he struggled with his writing and how he got his first short story published, aged 11. He talks about his family, his process, his demons as well. And he gives incredible tips on how you can become a writer yourself.
Show Your Work! by Austin Kleon : A great inspirational book to help you realise that you need to show your work around you. If you keep things for yourself, you’ll never show people how great you are. Don’t be shy!
Daily Rituals by Mason Currey : This book helped me a lot in the realisation of the fact that I don’t need to write 2,000 words to be a writer. Currey describes the rituals of hundreds of creatives, whether they are musicians, sculptors, writers, etc.
