Writing is a skill that can be learned and improved with practice. Everybody writes badly before they write well.
The Hemingway editor is a writing tool that helps make your writing bold and clear:
Some writers I know do all their writing in the app and then paste it into their editor of choice.
I pasted in a tutorial I wrote a while back and it found 3 hard to read sentences, along with a passive-to-active voice suggestion. If you tend to use complicated words, it will suggest simpler ones.
If you want to sound bold and to the point – like in a conference talk – then Hemingway's ghost might have some useful advice for you.
Have a lovely day,
