Harper grammar checker: Private and fast (so far)

I’ve been using LanguageTool to check my spelling (and to a lesser degree, grammar) here on my blog and it’s been fine, other than being kind of obsessed with commas. I recently came across Harper, which is an entirely offline, private grammar checker and started trying it out today.

My impressions so far:

  • No obsession with commas
  • It seems a tad more basic, but covers the essentials
  • UI is functional, but could be a little nicer
  • It really is fast
  • No AI!
  • It is distributed by Automattic, so if you have issues with the creator of WordPress, you may want to stay clear

I’m going to stick with it for a while, but if this sounds interesting to you, it’s available as an extension for Firefox and other browsers. Learn more about it here.
