Must have software

Hello,

I'm trying to create a list of not so well known software that are a must have for bloggers, IM Geeks and Content Creators. It also would be something I would invest for myself.

I'm not talking software like semrush or ahrefs that are widely known but mainly software like speechelo or doodle for example that could be add a nice touch to your software database and are not so well known.
It could also be assets (like video assets like lower thirds, etc).

What do you suggest to have and why?

GoCopy to make sure they are giving out unique content. Also is a good way to format the content.
A lot of people stress at the use of Grammarly but I think that Hemmingway is a bit more comprehensive.
Any good voice-to-text converter; helps with making the content conversational, instead of boring or too 'flat'.
