I watched a YouTube video that referenced Hemingway App as an authors’ tool. Here, I pasted some sample content from Hemo Sapiens: Origins to see what it might suggest.

It’s a short passage, but the only things it found were trivial nits.

Highlighted, the complaint is that the top sentence (in yellow) is too complex, so I should break it up as shown in green. The only difference is that it swapped the semicolon with a full stop and capitalised the next letter to begin the next sentence. It also declared the Grade 11 writing sample to be reduced to Grade 6.

Is this really worth more than the free trial or the time and effort?

It highlighted two other related challenges: both adverbs, and neither with remediation advice. In the sceen shot, you can read ‘slightly crispy’. Honestly, I don’t have a more direct way to show this information. I suppose if it was ‘crispy’, I could specify a ‘crunch’ sound. But how is the crispy crunch diminished when it’s just ‘slightly’? Enquiring minds want to know.
