Sometimes I feel my content is not where it could be and i was looking for some applications which can give some hints to how to improve.
as an example there’t that
http://www.hemingwayapp.com/
but this seems to be only useful for english users. Is there anything else similar to that, to get suggestions for making contents more readable, seo friendly, keyword density, etc.pp.?
Working for other languages other than english would be nice too…
I am not sure if i have been searching with the right keywords to find such applications, but if there is anything else that could help out, i am happy to hear…
So the question is, what tools do you use to get the most out of your content…
Too bad the Kirby Keyword Map did not work out for you. 
I’ve tested alot of SEO tools. Most of the tools that monitor the website costs money and are really expensive, like 100 USD each month.
If you just want to copy/paste your content manually, you can use tools like this:

The downside is that you need to switch between the tool and the site/panel all the time. It’s not a very nice way to work. That was the reason I built a field out of it. I think it needs to be in the panel to be simple enough.
I’ve used some similar tools for french maybe one could fit your needs :
thanks for the feedback,
ahrefs is quite a price for a monthly payment…
keyword planner is an obvious choice as someone might also want to set adwords
grammarly needs an registered account - even though it’s a free one - it might only work with english. haven’t really found an information about that though…
